8 Interesting FACTS ABOUT THE EARTH
Earth is the third planet from the sun in our solar system. Its name comes from the the old English and Germanic words meaning ‘the ground’.
Not only does Earth zoom through space, it also spins on its axis.
The Earth’s diameter measures a huge 12,800 kilometres, making it the fifth largest planet in the solar system.
People often think of Earth as a gigantic sphere. But, in fact, its shape is more like a squished ball that bulges out at the equator –– an imaginary line around the middle of the planet, exactly between the North Pole and the South Pole.
This ‘bulge’ is caused by the Earth’s spin and the effect of ‘gravity‘. Gravity is an invisible force that attracts objects towards each other.
Have you ever wondered why we have different seasons? We’ll tell you –– it’s because the Earth is tilted 23.4 degrees on its ‘axis’, an imaginary line straight through the middle of the planet form the North Pole to the South Pole.
