1.
a) Freeze-thaw weathering
b) Its mean annual rainfall is around 1100 mm and its mean annual temperature is around -11
c) Chemical weathering
d) Chemical weathering

2.
a) Freeze-thaw weathering is a type of weathering that effects the planets structure for example big rocks that have small cracks collect water in-between, freeze-thaw weathering freezes the water between and brakes the rocks apart.
b) Below freezing environments
c) because there is barely any water and the mean annual temperature does not reach freezing point or below.
d) A layer of rocky particles called Regolith.

3.
a) Chemical weathering is a type of weathering that changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions.
b) A full of rain yet hot environment.
c) Because there is no water to react with the minerals and because its not hot enough to react anyway.
d) Images below in order: Limestone, Granite and chalk
