Where can you find rockfall?

Answer 1

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.
