Why does the ocean recede before a tsunami?

Why is tibet a desert?

Why are recumbent folds found in mountain ranges?

Recumbent folds are commonly found in the core of mountain ranges and indicate that compression and/or shear forces were stronger in one direction. Extreme stress and pressure can sometimes cause the rocks to shear along a plane of weakness creating a fault. We call the combination of a fault and a fold in a rock an overthrust fault.
