Question

question 2
what causes the change from day to night and vice versa?
the orbit of the sun around earth.
the rotation of earth on its axis.
the moon’s rotation around earth.
the orbit of earth around the sun.

Explanation:

To determine the cause of day - night cycle, we analyze each option:

• The sun does not orbit Earth; Earth orbits the sun, so the first option is wrong.
• The rotation of Earth on its axis makes different parts of Earth face towards or away from the sun, causing day and night.
• The moon's rotation around Earth is related to lunar phases, not day - night cycle.
• Earth's orbit around the sun causes seasons, not day - night.

Answer:

The option "The rotation of Earth on its axis." (the third option among the given choices)
