Question

which movement causes day and night on earth?
rotation of earth
revolution of earth around the sun
earths elliptical orbit in space
moons orbit around earth

Explanation:

The rotation of the Earth on its axis causes day and night. As the Earth rotates, different parts of it face the Sun (day) or are turned away (night). The revolution of the Earth around the Sun causes seasons. The Earth's elliptical orbit affects the distance from the Sun but not day - night cycle. The Moon's orbit around the Earth affects tides, not day - night.

Answer:

rotation of Earth
