How was the Earth's crust formed and what processes were involved in its creation?

The Earth's crust was formed through a process called plate tectonics. This involves the movement of large sections of the Earth's outer layer, or lithosphere, which are called tectonic plates. These plates interact with each other in various ways, such as colliding, sliding past each other, or pulling apart. These interactions create features like mountains, volcanoes, and ocean basins, shaping the Earth's crust over millions of years.
