Shear in the Earth's crust refers to the stress that occurs when forces act parallel to a surface, causing layers of rock to slide past one another. This type of stress is often associated with tectonic plate movements and can lead to geological features such as faults and folds. Shear forces play a crucial role in the formation of earthquakes, as the accumulated stress is released when rocks finally slip along a fault line. Understanding shear helps geologists assess tectonic activity and predict seismic events.
