The Earth-Sun-Moon System

Question 9 • AZ-Earth and Space Science A (SC301)

Which movement causes day and night on Earth?

Answer
A
rotation of Earth
B
revolution of Earth around the Sun
C
Earth’s elliptical orbit in space
D
moon’s orbit around Earth

Explanation

Earth spins on its axis, and this movement is called rotation. The side facing the Sun experiences day, while the side turned away experiences night, so rotation of Earth is the correct choice. Earth’s revolution around the Sun takes a year and causes the seasons, not the daily cycle of day and night.
