Earth tide

Earth tide is like the ocean tide, but for the whole Earth! Just like the moon and sun tug on the ocean to make it go up and down, they also tug on the Earth, making it bulge a tiny amount.

The Earth has three types of tides: the Moon tide, the Sun tide, and the solid Earth tide. The Moon tide is the strongest because the Moon is closer to the Earth than the Sun is.

The solid Earth tide is a tiny bulge in the Earth's crust that gets pulled in different directions by the Moon and the Sun. The bulges are so small that you wouldn't even be able to see them, but they can still impact things like earthquakes and volcanoes!

Overall, earth tide is just the tiny movement of the Earth's surface due to the gravitational pull of the Moon and Sun.
