Question

In 3 sentences, explain how gravity causes Earth's tides.

Answer 1

Earth's tides are primarily caused by the gravitational forces exerted by the moon and the sun on our planet. The moon's gravitational pull creates bulges of water on the sides of Earth facing towards and away from the moon, causing high tides. As Earth rotates on its axis, different parts of the planet experience these bulges, resulting in two high tides and two low tides each day.
