Interesting Facts about earth.

                                      

1. There are more than 100 million pieces of junk orbiting Earth at about 17,000 miles per hour (27,000 km/hr).

16. A person who weighs 150.8 pounds at the North Pole weighs just 150 pounds at the equator. This is because the pull of gravity is stronger at the poles.

17. There is no solid land under the North Pole, just sea ice.

Earth is still an alien planet

18. Humans have explored only 5% of Earth’s oceans.

19. Over 68% of Earth’s fresh water is frozen in permanent ice, including Earth’s ice caps and glaciers.[4]

20. Because Antarctica has little vegetation and has a snowy landscape, it is one of the best places to find meteorites. More meteorites have been found in Antarctica than anywhere else in the world.

21. Earth actually has two North Poles. One is the magnetic pole, where the compass needles points. The other is the pole that the Earth’s meridians cross.

22. Yellowstone National Park is actually a huge volcano. Its most recent eruption was before humans lived. It hurled ash all the way to the Gulf of Mexico.

23. The only sea on Earth that is defined by ocean currents rather than a land border is the Sargasso Sea, which is located near Bermuda in the Atlantic Ocean. Its border is actually several ocean currents, which create a large area of still water full of floating seaweed.

24. The tallest waterfall on Earth is Angel Falls, which is 3,212 feet high. It is as tall as a 300-story building.

25. The closest point to space on Earth is not Mount Everest. Rather it is Mount Chimborazo, a 20,000 plus foot mountain in the Andes. Even though Mount Everest is taller from sea level, Mount Chimborazo sits higher on Earth's bulge.

26. One of Earth’s most toxic plants is the yew tree. Every part of the tree is poisonous, except its berries.

27. There are no black flowers on earth, though some are very dark shades of purple or red.

28. Lake Baikal in Russia holds 20% of Earth’s unfrozen freshwater. It is the deepest and oldest lake in the world.

29. The largest flower on Earth is also the smelliest. Native to Sumatra, The corpse flower smells like rotting flesh.

30. The tallest known tree on Earth is a redwood tree in a California forest. Nicknamed “Hyperion,” it is about twice as tall as the statue of liberty, at 380 feet high.

31. Earth’s rapid rotation coupled with its nickel-iron core creates a powerful magnetic field. The field protects the Earth from damaging solar winds.

32. Scientists believe that Earth’s stable climate is an anomaly that will end in the next billion years.

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

33. Someone standing on Earth's equator would be turning around Earth’s center at 1,000 mph. However, someone standing at the poles would be standing still (while turning in a circle, similar to standing on top of basketball.

34. The Earth travels through space at 67,000 mph. This means that everyone on Earth is 67,000 miles farther away than they were an hour ago.

35. The hottest temperature ever recorded on Earth’s surface was 136 degrees F in El Azizia, Libya in 1922.

36. The coldest temperature ever recorded was in Antarctica’s Vostok Station at a bone-chilling minus 128 degrees F.

44. Earth’s longest mountain range is actually underwater. Called the mid-ocean ridge system, it stretches over 80,000 km all around the world. It is almost 20 times longer than the longest range on the surface, which is the Andes Mountains. The entire ridge is completely volcanic.

45. Without the moon, Earth would still have wild changes in climate and be uninhabitable. The stabilizing tug of the moon tempers Earth, resulting in the minor tip that causes summer and winter seasons.

46. Earth has about seven quintillions, five hundred quadrillion grains of sand. Still, the known universe contains 70 thousand million, million, million stars in the observable universe, which means they're about 10,000 stars for every grain of sand.

52. Every day, between 10 and 20 volcanoes are erupting somewhere on Earth. However, the chances of them all erupting at once are almost impossible.

A tree can absorb as much as 48 pounds of carbon dioxide per year

53. There are about 3 trillion trees on earth or about 422 trees per person. However, the number of trees on the planet has slashed by nearly half since the beginning of human civilization. 

54. Over 15 billion trees are lost to due to human activity each year.

55. Since the Industrial Revolution, the earth’s temperature has increased by about 1.5 F.

56. The number of water molecules in ten drops of water is equal to all the stars in the known universe.

57. If there were a tunnel through one end of the earth to another, it would take about 42 minutes to fall all the way through.
