Types of Earth's Crust

The Earth's crust is composed of various types of rocks and minerals. The types of Earth's crust include:

1. Continental crust: - The continental crust is primarily composed of granite and is less dense than the oceanic crust. - It is thicker, with an average thickness of about 35 km. - The continental crust is the outermost layer of the Earth and forms the continents and continental shelves. - Source: 2. Oceanic crust: - The oceanic crust is primarily composed of basalt and is denser than the continental crust. - It is thinner, with an average thickness of about 7 km. - The oceanic crust is located beneath the oceans and is constantly being created and destroyed through the process of seafloor spreading and subduction. - Source: 3. Mohorovičić discontinuity (Moho): - The Mohorovičić discontinuity, commonly referred to as the Moho, is the boundary between the Earth's crust and the underlying mantle. - It represents a significant change in seismic wave velocities, indicating the transition from the crust to the mantle. - The Moho is typically located at an average depth of about 8 km beneath the oceanic crust and 32 km beneath the continental crust. - Source: These are the primary types of Earth's crust, each with distinct compositions, thicknesses, and geological significance.
