Erosional landforms occur more often in the colder periods of the year because in this parts of the year there's usually more rain, and also there's snow ,and most importantly ice. The rain and snow contribute to the chemical decomposition of the rocks, while the ice with it's pressure contributes to the physical decomposition of the rocks, by literary increasing it's volume inside the cracks of the rocks and break them from the inside.
Earth's gravity pulls matter downward, toward its center. It pulls precipitation down from clouds and pulls water downhill.
Shearing creates strike-slip faults that could possibly occur in the San Andreas Fault. Shearing is structural component of rock which refers to its texture and fault mechanics. Simply put, it is rock deformation that is caused by compressive stress. The study of shearing in rocks is related to structural geology.
A stationary front is depicted in the picture at L. A stationary from is a narrow zone separating two air masses in which neither air mass is displacing the other. When this occurs there is a stall in the motion of the front. The blue triangles point away from the cold air and the red semicircles point away from the warm air.
