Earth; often called as the green earth or the blue planet, is essence of life. Earth is giver of life, provider of natural resources to human existence but somehow, it is getting damaged due to the side-effects of global warming.
Green earth symbolizes life and happiness and if we will not take care for our earth then it can turn out to some deadliest Natural Disasters. Check out some amazing earth facts with us and I request readers of Kids Consultant to plant more and more trees and make our beautiful earth a ‘Real Green Earth’, as, now it’s our time to return.
1. Earth is the only planet known to have existence of life, Earth is also denoted as Green Earth, World, and the Blue Planet. Latin name of Earth is Terra or Gaia.
2. About 70% of the Earth’s surface is covered in water. The abundance presence of water on Earth’s surface makes it a “Blue Planet” from rest of the planets in the Solar System.
3. Earth is not a perfect sphere in fact it is a squashed sphere. It is called an oblate spheroid which means that it is slightly flattened on the top and bottom poles.
4. Earth is a terrestrial planet and is the largest of the other four solar terrestrial planets in size and mass. Earth also has the highest density, the highest surface gravity, the strongest magnetic field, and fastest rotation in comparison to rest four terrestrial planets.
5. The mechanically rigid outer layer of the Earth, the lithosphere, is broken into pieces called tectonic plates. Earth is the only planet in the Solar System with plate tectonics. The Earth’s plates move just a few inches a year.
6. There are seven major plates of the Earth, they are the Pacific, North American, Eurasian, African, Antarctic, Indo-Australian, and South American.
7. The Earth’s atmosphere is thickest within the first 50 km and extends up to 10,000 km above the surface of the planet.
8. The outermost layer of the earth’s atmosphere is called the exosphere.
9. The lowest layer of earth’s atmosphere is troposphere. It is also known as weather layer, nearer to the earth’s surface. It extends up to 15 km above the earth’s surface.
10. The Earth is like a giant magnet, with both north and south poles. The Earth’s molten iron core creates a magnetic field.
11. Earth’s magnetic field extends from the earth’s surface to thousands of km to magnetosphere where the Earth’s magnetic fields interact with the solar wind. The magnetosphere deflects particles in the solar wind around the earth and protects us from harmful rays.
12. On an actual calculation earth takes 23 hours, 56 minutes and 4 seconds to complete one rotation on its axis.
13. The earth actually takes 365.2564 days to complete one revolution around the sun on its orbit; remaining .2564 days make the calculation for the formation of a leap year. Every 365.2564 mean solar days, or one sidereal year. Earth orbits the Sun at an average distance of about 150 million kilometres.
14. Tilt of the earth’s axis, and orbit of the earth around the sun are the 2 major causes behind seasonal change in climate.
15. Earth’s has only one moon, a large, terrestrial natural satellite, with a diameter about one-quarter of the Earth’s and is the largest moon in the Solar System.
16. The Earth is a provider of natural resources which are exploitable by humans for useful purposes, but some of it is non-renewable resources, such as mineral, fuels, that are difficult to reproduce on a short time span, as it takes millions of years to form. Large deposits of fossil fuels are obtained from the earth’s crust, consisting of coal, petroleum, natural gas and methane.
17. Under the earth’s oceans, we can find earth’s largest mountain ranges that circle the planet like the stitching on a baseball.
18. Magma is the hot liquid rock under the surface of the Earth, it is known as lava after it comes out of a volcano. The volcanic rock known as pumice is the only rock that can float in water.
19. Earth’s Amazon rainforest is the largest tropical rainforest on Earth and home to one-third of the earth’s land species or planet’s biodiversity; it releases one-fourth of Earth’s freshwater; is home to native and traditional cultures; also plays a key role in global carbon cycles and climate.
20. Catastrophic side of earth’s natural and environmental hazards are extreme weather such as tropical cyclones, typhoons, hurricanes as well as other natural calamities like earthquakes, landslides, floods, tornadoes, tsunamis, volcanic eruptions, droughts, sinkholes, blizzards, wildfires,and other calamities or disasters.
