Revolution

Answer 0

The complete trip that Earth makes around the Sun. This takes one year or 365 and 1/4 days. Along with the tilt of Earth’s axis, this trip makes the Earth have seasons.

Question 1

Rotation

The path Earth or a planet follows around a star.

Winter

Answer 9

The coldest season of the year. Winter happens because Earth is tilting away from the Sun and the sunlight is more slanted in that area, causing temperatures to be cold.

Question 10

Season

Answer 10

Caused by the revolution of the Earth around the Sun and the tilt of the Earth’s axis. We experience 4 seasons, Spring, Summer, Fall, and Winter.

Question 11

Year

Answer 11

A year on Earth takes 365 and 1/4 days. This is the amount of time it takes Earth to revolve around the Sun.

Length of Earth’s Rotation

Answer 12

One day or 24 hours. We have daytime and nighttime.

Question 13

Length of Earth’s Revolution

Answer 13
