What are some cool facts about earth?

Answer 1

Earth is the third planet from the sun, the fifth largest and the densest of eight planets in the Solar System. It is sometimes called the world, the Blue Planet or by its Latin name, Terra.

Home to millions of different species, including humans, Earth is the only place in the Universe where life is known to exist.

The planet formed 4. 6 billion years ago (Earth's moon was formed 4.5 billion years ago), and life appeared on its surface within a billion years ago.

Scientists have been able to reconstruct detailed information about the planet's past.

30% of Earth is terrain (land), and 70% of it is water from the Ocean, lakes etc.

Earth is made out of the following Chemical elements:

• oxygen 46.6 %
• aluminum 8.1
• iron 5
• sodium 2.8
• magnesium 2.1
• calcium 3.6

• potassium 2.6
• Silicon 27.7

  Other 1.5
