What are the 4 layers of the Earth?
The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth’s surface.
What is the 3 layers of the Earth?
Earth’s interior is generally divided into three major layers: the crust, the mantle, and the core. The hard, brittle crust extends from Earth’s surface to the so-called Mohorovicic discontinuity, nicknamed the Moho.
