Why does the earth interior is moving?

Answer 1

First, because the core is mainly liquid and the Earth is rotating. Second, The Earth get a little tug from the moon.

Answer 2

The movement of Earth's interior is mainly due to the process of convection, where heat from the core drives the circulation of mantle material in a cycle of heating, rising, cooling, and sinking. This movement creates plate tectonics, causing continents to drift and generating geological phenomena like earthquakes and volcanoes.

Answer 3

We live on the Earth's crust, which floats on the mantle. The mantle is semi-molten rock and the different temperatures cause the molten rock to rise and sink, which causes the movement.
