10 Interesting Facts about Earth

Earth is a home for millions species, bank of tons natural resources, space of countless buildings and only on earth we can enjoy oxygen for free. In this post, we are going to uncover 10 interestingearth facts that might help you to understand how the planet works closely.

Fact 1; Earth Age and the upside of Tsunami

Old earth

Today, Earth is around 3 billion to 5 billion years old. Earth is the only planet in solar system that composes oxygen, hydrogen and other important element to support life. Earth is also the only planet in solar system that has plate tectonic. Plate tectonics are moving and recycle microscopic plant under the ocean. If plate tectonic stops moving, earth will overheat and be too harsh to be populated.

Fact 2: Shape of the earthEarth is not perfect round like a ball. The shape is similar as a pumpkin. Earth become that way because of its rotation and revolution activities.

Fact 3: Earth Composition
The surface of the earth composes 30,1% Oxygen, 32,1% Iron and 13,9 % magnesium. If we dig deeper, we can find more iron. The inner layer and deep core of the earth compose around 88% of iron
Fact 4: Earth Spinning speed

Earth has timeless schedule to circle the sun. The speed is around 1 thousand mile per hour. To circle its own center, earth needs about 23:56:04 seconds. To complete one revolution circling the sun, earth requires around 365,2564 days. The number of day is not constant so that is the reason why February has 28 days every common years and 29 days in leap years.
Fact 5: Gravity.

Map of Gravity

The surface of the earth has different gravity. In equator, earth has 2-3% least gravitational pull because of centripetal force. However, this gives no visible benefit to human or population that lives in the area

Fact 6: WaterOnly 30% surface of earth is dry land. Most area of earth is waterbed and wet lands.80 percent of total species of the earth are living under water and taking less oxygen. The bad news is, almost 100 percent area of the earth suffers sudden temperature changes in the last decade. You might call it global warming effect.

Fact 7: Does earth Heavier?Scientists published a report that 2,000,000 lbs of space dusts fall from the outer space yearly. Small percent of it carries unfriendly microbes and bacteria. From the conclusion, it is true that today’s earth is heavier that last year
Fact 8; Rainforest treesIn the past, Earth enjoys benefit from rainforest tress that populated 14 percent of Earth’s dry land. Today, most of this tress is gone and that 14% turns to be 2 percent only.

Fact 9; AntarcticaAntarctica is a place where earth saves most of its water. Antarctica delivers 70 percent of all fresh water available in the planet. If Antarctica dry, average sea level will rise 200 feet and it will drown many metropolitan cities on the world.
Fact 10; 2nd and 3rd moon

3753 Cruithne

Beside moon, two asteroids circle the earth and revolve the sun. First asteroid is 3753 Cruithne and the second asteroid is 2002 AA29. The diameter of 3753 Cruithne is 5 km wide and 2002 AA29 is mere 60 meters. These two asteroids are not available unless using scopes.

I realize these 10 facts about earth are not enough for you. If you have time, you can go to Wikipedia to find out more. Most of these data are taken from that source.
