Planet Earth

The Earth is shaped like a sphere. Think of a cricket ball and that’s the shape of the earth.

Earth is the fifth largest planet in the Solar System and the third planet from the sun.

Earth takes 365 ¼ days to make a complete revolution around the sun. Earth also spins (rotates) on its axis every 24 hours.

The axis is an imaginary line that runs from the North Pole to the South Pole.

Earth has a slight tilt at an angle of 23 ½o .

EARTH’S Atmosphere

A layer of gases surround the earth and this is called the atmosphere. It is sometimes called Earth’s blanket because it protects the earth from getting too hot or too cold.

The gases that make up the atmosphere are:

      Nitrogen (78%) – Most Abundant gas in the atmosphere

      Oxygen (21%)

      Carbon Dioxide (0.03%)
