Continental vs. Oceanic Crust: The Earth's crust is not a uniform layer; it has two distinct types: the continental crust and the oceanic crust.
Continental Crust: This is the part of the crust that makes up the continents. It is generally thicker and less dense than oceanic crust. While its thickness can range from 30 to 70 kilometers, especially under mountain ranges like the Himalayas, the average thickness is approximately 35 km.
Oceanic Crust: The oceanic crust is much thinner, averaging only about 5 to 10 kilometres thick.
