What is the difference in depth of the earths crust in different parts of the region?

The Earth's crust varies significantly in depth depending on location. It is generally thinner under oceanic regions, averaging about 5-10 kilometers, while continental crust can reach depths of 30-70 kilometers. Additionally, mountain ranges, formed by tectonic activity, can have crust that extends even deeper. This variability is influenced by geological processes such as plate tectonics, sedimentation, and volcanic activity.
