Front

What is the axis of the Earth?

Back

The axis of the Earth is an imaginary line that runs from the North Pole to the South Pole, around which the Earth rotates.

Front

What happens to light when it enters a water droplet?

Back

When light enters a water droplet, it slows down and bends, which is called refraction.

Front

What is the term for the path the Earth takes around the Sun?

Back
