Top 10 Amazing Earth Facts

Top 10 Amazing Earth Facts


As well known and well travelled as our planet is, there are still new things being discovered every day. In fact, most of our oceans haven’t even been explored yet which is why when new depths are located; they often come with hundreds of new species. Rain forests offer up new animals and plants as often as we can explore them. The Earth is constantly changing, shifting, and exposing new secrets for humans to marvel at. It took many years and many great minds to solve the problem of getting through Earth’s atmosphere into the wide expanse of space beyond. Here are ten amazing facts about our home that you may not be aware of.

10. The Atmosphere

Earths-Atmosphere

Many layers of atmosphere coat our planet including the mesosphere, ionosphere, exosphere, and the thermosphere, but it’s the troposphere, closest to the planet itself, that supports our lives and is, in fact, the thinnest at only about 10 miles high.

9. Deserts

Desert

Believe it or not, most of the Earth’s deserts are not composed entirely of sand. Much, about 85% of them, are rocks and gravel. The largest, the Sahara, fills about 1/3 of Africa (and it is growing constantly) which would nearly fill the continental United States.

8. The Big Blue Marble

Oblate Spheroid

The Earth is, in fact, not really round. It is called an oblate spheroid meaning it’s slightly flattened on the top and bottom poles.

7. Salty Oceans

Ocean

If you could evaporate all the water out of all the oceans and spread the resulting salt over all the land on Earth, you would have a five hundred-foot layer coating everything.

6. Lakes and Seas

Caspiansea-1

The largest inland sea (or, sometimes called a lake) is the Caspian Sea which is on the border of Iran and Russia.

5. Mountains

Andes

The Andes Mountain range in South America is 4,525 miles long and ranks, as the world’s longest. Second Longest: The Rockies; Third: Himalayas; Fourth: The Great Dividing Range in Australia; Fifth: Trans-Antarctic Mountains. For every 980 feet you climb up a mountain, the temperature drops 3-1/2 degrees.

4. Deep Water

Baikal

The deepest lake in the world is in the former USSR and it is Lake Baikal. It has a length of 400 miles, a width of roughly 30, but its depth is just over a mile: 5,371 feet down. It is deep enough, so is speculated, that all five of the next largest lakes: The Great Lakes could be emptied into it.

3. Shaky Ground

Earthquake

Earthquakes can be catastrophically destructive and many a year are deadly. However, the Earth releases about 1 million a year, almost all are never even registered.

2. Hot, Hot, Hot

Libya

Most people believe that Death Valley, California, U.S.A. is the hottest place on Earth. Well, occasionally it is, but the hottest recorded temperature was from Azizia in Libya recording a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922. In Death Valley, it got up to 134 Fahrenheit on July 10, 1913.

1. Dust in the Wind

Space Dust

Experts from the USGS claim that roughly 1,000 tons of space debris rains down on Earth every year.

Simple Steps for Clean Air

Simple Steps for Clean Air

Air pollution is caused by each one of us. If trends continue we will soon be forced to buy clean air as we are doing for water these days. Here are some steps you can take and motivate others join in for a that breath of clean air!! 

  1. Use mass transport system as much as possible. Save money and save air!!
  2. For shorter distances, walk or cycle. Take a cycle rickshaw instead of autorickshaw.
  3. If you use your own vehicle, adopt car-pooling. Share your vehicle with colleagues and neighbours while traveling to school/ office/ same destinations.
  4. Park vehicle in such a way that they can be moved out in first gear and not in reverse gear. The fuel consumption and engine load is maximum in reverse gear, especially when you are starting a cold engine.
  5. Switch off the engine when the stoppage period is more than two minutes (especially at red lights). Anticipate stops and decelerate in advance.
  6. Driving is most efficient at 50- 60 Km/h in top gear. Speed of 80- 100 Km/h increases fuel consumption.

  7. Always use unleaded petrol in vehicle fitted with catalytic converter. A catalytic converter is a device designed to control exhaust emission.

  8. Regular and systematic maintenance of vehicle along with good driving habits (mentioned above) help in reducing fuel consumption and hence curb air pollution.

  9. Note down the number of the polluting vehicle and report to traffic police. 

  10. Plant and nurture as many trees as possible and take care of the existing ones. Every tree you plant clears the atmosphere by absorbing carbon dioxide. Have plants inside the house too.

  11. Do not burn waste or leaf litter. Give paper and plastic to ragpickers and composting garden waste.

  12. Do not burst crackers on Diwali and other occasions. There are other ways of celebrating festivals which do not harm our environment. 

  13. Electricity is primarily produced by burning coal.  So saving electricity means reducing air pollution. Switch of lights and fans when not in use. 

  14. Do not use chemical based insecticides or pesticides, instead use herbal ones. 

  15. Avoid products made of CFC's like aerosols and styrofoam cups.

Facts about Global Environmental Changes

The science of climate change is complex, but everyone should know the basics: the Earth is heating up because gases produced from vehicles, power plants, deforestation, and other sources are building up in the atmosphere, acting like a thick blanket over our planet.

We can all reduce climate change by doing our part

The Facts About Climate Change

  • FACT: Average global temperatures increased by about 1 degree Fahrenheit over the 20th century.
  • FACT: The United States, India & China are the three single largest polluters in the world.
  • FACT: 15 percent of carbon emissions come from deforestation and land use change.
  • FACT: The Golden Toad (Bufo periglenes) is thought to be the first species to go extinct because of climate change.
  • FACT: Personal cars and 2 wheelers trucks in India emit 50% percent of its carbon emissions.
  • FACT: Air conditioning and heating account for almost half of electricity use in the average American home.
  • FACT: Climate change is linked to stronger hurricanes, increased droughts and increased coral deaths from bleaching.
  • FACT: Climate change is linked to an increase in disease carrying pests that lead to the increased spread of diseases such as dengue fever, malaria, lyme disease and West Nile virus.

50 small ways to help the environment

Pick one, and start today.

1. Take a shorter shower.
If you take long showers, consider cutting it short by a few minutes. You’ll conserve water, and the electricity needed to heat up the water, lowering your utility bills and reducing your energy consumption at the same time.

2. Use a rag or hand towel instead of napkins or paper towels.
Reusing items instead of using disposable items is almost always a better thing for the environment. Reduce the need to cut down trees, the power needed to turn them into napkins, and the space in the landfill once you throw them away.

3. Don’t print at least once today.
Instead of automatically hitting the “print” button, think of whether you really need a hardcopy of that document. Can you email it instead? File it on your computer instead of your file cabinet? Read it on the computer instead of on paper? You don’t have to eliminate printing entirely, but holding off on that “print” button once in awhile could greatly reduce your paper consumption.

4. Carpool once this week.
Have a friend or family member or co-worker who makes roughly the same commute as you? Try riding together at least once. It save on fuel consumption, cuts your fuel spending, reduces greenhouse emissions, and you can get a good conversation at the same time.

5. Turn off the TV for an hour.
Reduce your energy consumption and get outside and play a sport. Or garden. Or just take a walk. You get healthy and enjoy the natural beauty of your surroundings.

6. Turn off the lights.
If you leave a room, even for a little while, turn off the lights. You don’t need it, and it’s wasting energy.

7. Use a coffee mug instead of disposable.
If you routinely use disposable cups at work or on the road, use a ceramic coffee cup or a travel mug, reducing the amount of trash you throw away.

8. Use CFC light bulbs.
If your light bulb burns out, replace it with a Compact Flourescent bulb (those spiral-looking ones). They’re more expensive, but if you just replace them one at a time, it doesn’t cost much, and the energy savings is great. And as they last longer, over the long run, you’ll save money.

9. Skip the foil and plastic wrap.
Use reusable plastic food containers to store leftovers or other food in the fridge and cabinets, instead of disposable material.

10. Inflate your tires.
Many people don’t realize that their tires are under-inflated. Check the recommended pressure for your tires, and fill them up to that pressure. It only takes a few minutes, but it will save you on fuel consumption (a little) and more importantly, make your tires last longer and reduce the rubber that’s worn off your tires.

11. Clean up.
If you go to the beach or a park, leave it cleaner than when you got there. Pick up some cans and other trash that were there when you arrived. Takes a couple minutes, and makes the world a nicer place to live in.

12. Talk to your kids about the environment.
Just a 5-minute conversation every now and then about fuel consumption, greenhouse emissions, wasting food and trash, energy consumption, preserving habitats ? this can help educate your children about the issues that will be affecting them tomorrow. And an educated population will do more to help the environment than anything else.

13. Reuse printed paper.
If you have non-sensitive documents that have been printed out, but are no longer needed, try marking the printed side, and using the clean side for non-official printing. In fact, if you can get your office to do this, you’ll save tons of paper a year.

14. Turn down your water heater.
Most people have their water heater’s thermostat turned up too high, wasting energy. Turn it down to 130 degrees, saving energy but still hot enough to kill bacteria.

15. Plant a tree.
It really doesn’t take much time, and over time more trees in your community can make a difference. Do a few every year, and encourage others to do the same.

16. Hang out your clothes.
If it’s a nice sunny day, hanging clothes only takes a few minutes, and you’re using solar power instead of electricity to do the job. It also makes your clothes last longer.

17. Buy a manual reel mower or electric mower.
If you’re looking for a new lawn mower, and you have a small yard, consider getting a manual one. They’re much advanced from the reel mowers of our grandparents’ generation, much quieter, cheaper, and they save on fuel and pollution. Electric mowers are also quieter and use much less energy.

18. Get a low-flow shower head.
Stop at the hardware store on your way home, and get a low-flow shower head. Takes a few minutes to install, and it’ll save gallons of water a day.

19. Lower your thermostats.
If you use heating, get by with less heat and wear warmer clothes. If you use air-conditioning, get by with less cooling and wear cooler clothes.

20. Participate or organize a clean-up.
Sure, this’ll take a little more of your time, but if you don’t have much to do on the weekends, this can be tremendously fun and fulfilling. Clean up a beach, a street, a park, a lake or a river.

21. Avoid fast food.
Instead, eat at home or at a sit-down restaurant. Fast food restaurants are one of the worst polluters of the environment, both in the massive amounts of beef they must raise, in the wasted packaging, and in the energy they use in so many ways. And they’re tremendously unhealthy.

22. Use acryllic paint.
Oil-based paints are toxic and create a lot of pollution during manufacturing. Instead, if you’re going to buy paint, buy acryllic.

23. Coat your roof.
This’ll take up an afternoon, but you only have to do it once every few years. And it’ll save you a lot of money and energy in heating and cooling over the long-term, more than making up for the cost of paint.

24. Clean your filters.
Clean the filters of your air-conditioners once a month to improve energy efficiency. While you’re at it, change your car’s filters as recommended in your manual.

25. Telecommute.
I know, sounds great, where do I sign up? But if you talk to your employer about even a limited telecommuting schedule, you can save a lot of fuel and time, and be more productive at the same time. Just be sure to get a lot more done at home than you do at work to make your case for an expanded telecommuting schedule down the road.

26. Wash clothes in cold water.
Hot water is unnecessary for most clothes. When needed, use warm water.

27. Fill your toilet tank.
Put a plastic bottle or two, filled with water and rocks, in your tank to reduce the amount of water used in each flush.

28. Buy recycled products.
As much as possible, get the recycled version of products you buy.

29. Recycle.
Sure, it’s a regular practice in some places, with curb-side pickup of recycled waste. But in other places, there’s no such thing. Instead, create a few containers for paper, plastic and aluminum waste in your home or office. When it’s full, drop it off at a local recycling center (look in your phone book) on your errands day.

30. Buy a smaller car.
You won’t be able to do this today, probably, but the next time you’re in the market for an automobile, get a smaller and energy-efficient car rather than a big, lumbering one. It’s one of the best things you can do to reduce your fuel consumption.

31. Buy a smaller home.
The next time you’re home-shopping, instead of buying the McMansion, look for a smaller home that’s big enough to meet your needs comfortably. Reducing the amount of stuff you own is a good way to need less house. It’s cheaper, and requires less energy to heat and cool. And easier to clean at the same time.

32. Look for energy efficiency.
When you’re looking to buy appliances, be sure to research the most energy-efficient ones. They may cost a little more, but they’ll more than make up for that in the long run with lower energy bills.

33. Water grass early in the morning.
Reduces the amount of water you need to keep your grass looking fabulous.

34. Plant shade trees near your house.
It’ll take awhile before they can make a difference, but shade trees greatly reduce the need to cool a home.

35. Use rechargeable batteries.
Instead of throwing your batteries away all the time, reuse rechargeable batteries. Costs a little more, but cheaper in the long run.

36. Buy used.
Instead of buying new clothing, furniture, cars, whatever, look to buy used instead. You can get them for cheaper, and still get quality – all the while reducing the need to produce more stuff.

37. Walk instead of drive.
You don’t have to do this all the time, but walking the short trip to a store, or to lunch from work, or some other short trip like that, can reduce the amount of fuel you use over the long term, and you shed some fat at the same time. Or at least burn off that morning donut.

38. Unplug appliances.
If you don’t use an appliance several times a day, it’s better to unplug it, as they often use energy even when turned off

39. Unload your car.
Remove excess weight from your car (such as stuff that might be in the trunk) to reduce the amount of fuel you use.

40. Try cycling.
Biking to work or around town can be a great way to get in some exercise and save fuel.

41. Install a water filter.
If you buy a lot of bottled water, use your tap instead. Some places need a filter to make tap water taste drinkable, but they don’t cost much and they can save money, water, and plastic bottles over time.

42. Use cloth shopping bags.
Don’t cost much, and can save a lot of paper or plastic.

43. Mend your stuff.
Try not to throw stuff away and buy new stuff if the old stuff can be fixed. Torn clothing? Takes a few minutes to sew up.

44. Compost.
It’s not hard to set one up (look it up online), and you can save a lot of waste from the landfill and help your garden at the same time.

45. Try mass transit.
Millions of people use it, and it saves tons of fuel. If you don’t already, give it a try.

46. Buy in bulk.
Reduces the need for packaging, and costs less.

47. Buy durable.
Look for long-lasting, well-made products instead of cheap, disposable ones. Use less disposable plates, cups, utensils. Use cloth diapers instead of disposable.

48. Use your oven less.
The oven not only uses a lot of energy, it heats up your kitchen, requiring more cooling. Instead, use toaster ovens, crockpots, microwaves, and electric grills when you can. And when you do use your oven, open it less – you lose 25% of the heat every time you open the oven door.

49. Join a local organization.
Just about every community has one or more environmental organizations. It’s not hard to sign up, and when you have the time, you can volunteer for things that will clean up your community and make it a nicer place to live.

50. Join Blog Action Day.
By joining the rest of the blogging community in talking about the environment for one day (Oct. 15), you will be helping to raise environmental consciousness, with just one blog post. What can be easier than that?
