Learning Objective: Students will know about the movement of earth- revolution.

Movement of the Earth – Revolution

While rotating on its axis, the Earth also goes around the sun. The Earth follows a fixed path
during its journey around the sun. This path is called the orbit of the Earth. This movement
of the Earth around the sun is called revolution. The Earth takes 365 ¼ days to complete
one revolution. This period is called a year.

The revolution of the Earth and the tilt in its axis cause change of seasons. We experience
summer, winter, spring and autumn, depending on the amount of sunlight that we get at
different times of the year.

Learning Outcome: Students learnt about revolution and its effect.
