Explain the sequence of geological events that could link rising temperatures to more rockfalls.

Expansion and contraction of rocks

Explanation:

As the temperature increases the rocks will expand as per law of science. When night falls the rocks will cool and contract. The smaller differences in daytime and nighttime temperatures are not enough to cause any significant changes. However, with increasing daytime temperatures and decreasing nighttime temperatures, the temperature difference is great.  This causes,  a larger expansion and a tighter contraction. This constant expansion and contraction eventually creates cracks in the rocks that become larger and may propagate deeper into more rocks.

This scenario is also true for changing seasons between winter and summer. Hotter summers and colder winters mimic the expansion and contraction for night and day temperatures.

Constant cracking will eventually lead to weakening of structures and eventual breaking and eventual falls. This is a dangerous occurrence for animals and people in these areas and caution must be observed for "falling rocks".

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
