ROCKFALL FORMATION, CONDITIONS AND PROCESSES
Rock fall is when a mass of rock fragments fall from a steep, bare, vertical slope. The conditions for this process are the rock must be well jointed allowing water to enter the cracks. This only takes place when the rock is weakened, i.e. the rock is weakened by freeze thaw, which is when water goes into the rocks cracks, freezes and expands breaking off the rock. It can also happen when the rock is expanded and contracted by the extreme heat which causes the rock to break off due to the constant movement of the rock. If this goes on repeatedly the broken rocks will collect at the bottom of the slope, this can be called scree.
Conditions
-Steep, bare and vertical slope
-Well jointed allowing water to go into cracks meaning freeze thaw process will take place
-Hot weather conditions, to allow exfoliation process (onion skin weathering) or cold conditions to allow freeze thaw process.

Why is rockfall the fastest type of landslide?
because the weight of the rocks make them go even faster with gravity

What is rockfall?
For rockfall to occur the conditions required are extreme weather such as freezing temperatures for freeze thaw to take place, heavy rainfall which gets into the cracks, freezes and expands and weakens the rocks causing them to be unstable and gravity causes the rocks to fall freely through the air to the surface where gradually a scree slope is formed.
