The earth is going to make two movements:

​

Earth

• Rotation - lasts 24 hours.

• Revolution - lasts 365.25 days

​

Our home planet Earth is a rocky, terrestrial planet. It has a solid and active surface with mountains, valleys, canyons, plains and so much more. Earth is special because it is an ocean planet. Water covers 70% of Earth's surface.

Earth´s surface

Our atmosphere is made mostly of nitrogen. Nitrogen makes up about 78% of Earth’s atmosphere. Nitrogen gas is all around us, comprising the vast majority of the air we breathe.

Atmosphere and Nitrogen

• A day on Earth lasts a little under 24 hours.

• One year on Earth lasts 365.25 days. That 0.25 extra means every four years we need to add one day to our calendar. We call it a leap day (in a leap year).
