Answer to Question 1

The oceanic crust is approximately 7 kilometers thick, and is composed homogeneously of the dark igneous rock basalt. By contrast, the continental crust averages 3540 kilometers thick but may exceed 70 kilometers in some areas (like the Himalaya). The continental crust is also not very homogenous, though the upper part is mostly granitic there are many rock types that comprise it.

Answer to Question 2

Tsunamis are seismic sea waves. Most tsunamis are generated by displacement along a megathrust fault that suddenly lifts a large slab of seafloor.
