Rockfalls occur each year due to steep slopes at a near vertical (80-90 degrees). There is no soil or vegetation on the rock face which causes instability and is a huge contributor to the formation of a rock fall. The rock face is usually always exposed and suffers from weathering on a regular basis this causes the well jointed rock to become weaker. Freeze thaw is also another condition, water seeps into cracks of the well jointed rock face and freezes during the night. Soon it expands , eventually the rock will crack and loosen causing the rock to fall.
Higher class 5A noticed that you had 'Freeze thaw is also another condition'. We would change this as Freeze thaw is a process. We would add that scree settles at an angle of around 30 degrees and protects the slope from further weathering.

It is a geological phenomenon, which includes a wide range of ground movement; such as rockfalls, deep failure of slopes and shallow debris flows, which can occur in offshore, coastal, and onshore environments.
no they can occur multiple times per year
The next Year of the Dog will occur in 2018.

A equinox occur's only about 2 times a year.
About 50 earth quakes occur in each day so we can say that 18250 to 20000 earth quick occur a year.
