Thinnest layer

Crust

Composed of peridotite

Core

Moho Barrier

Separates the crust and

mantle

The mantle is composed of peridotite. The crust is the thinnest layer. The core creates a magnetic field. The Moho Barrier separates the crust and mantle.

1. the region of the earth's interior between the crust and the core, believed to consist of hot, dense silicate rocks (mainly peridotite).

2. crust

3. The crust is the outermost solid shell of a rocky planet, dwarf planet, or natural satellite

4. Mantle

5. Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle

6. The magnetic field is generated by electric currents due to the motion of convection currents of molten iron in the Earth's outer core driven by heat escaping from the core, a natural process called a geodynamo.

7. the boundary between the crust and the mantle in the earth

8. Mohorovicic discontinuity
