How day and night happens

What causes day and night cycles?

• The rotation of the Earth

• The orbit of the Moon

• The tilt of the Earth's axis

• The movement of the Sun

How does the tilt of the Earth's axis contribute to the variation in daylight hours and changing seasons?

• By affecting the angle at which sunlight reaches different parts of the Earth

• By changing the speed at which the Earth rotates on its axis

• By altering the distance between the Earth and the Sun

• By influencing the gravitational pull of the Moon on the Earth

How does the Earth's revolution around the Sun affect the length of days and nights?

• By changing the angle of sunlight

• By altering the speed of the Earth's rotation

• By increasing the distance between the Earth and the Sun

• By changing the tilt of the Earth's axis

How do Earth's rotation, axis tilt, and revolution contribute to the regular day and night cycles?
