What causes day and night on Earth?

Back

Day and night are caused by the rotation of Earth on its axis. When one side of Earth faces the sun, it experiences day, while the opposite side experiences night.

What is the tilt of Earth's axis and how does it affect seasons?

Back

Earth's axis is tilted at an angle of about 23.5 degrees. This tilt causes different parts of Earth to receive varying amounts of sunlight throughout the year, leading to the changing seasons.

What is the role of the moon in Earth's tides?

Back

The moon's gravitational pull creates bulges in the oceans, leading to high and low tides. The position of the moon relative to Earth affects the strength of the tides.
