The crust was formed over 4 billion years ago, when the Earth was still in its early stages of development. It's believed that the crust was created through a process of magmatic differentiation, where lighter rocks rose to the surface and heavier rocks sank to the bottom. This process is still happening today, with volcanic eruptions and earthquakes shaping our planet's surface.
But here's the cool thing about the crust: it's not just a static layer of rock. It's dynamic, with plate tectonics causing the plates to move, collide, and even create new landforms. This process has shaped our planet's surface over millions of years, creating mountain ranges, oceanic trenches, and volcanic islands.
