Hard rocks , such as granite, weather more slowly than softer rocks , such as limestone. Differential weathering happens when softer rocks weathers away and leaves harder, more resistant rock
behind. The figures below show an example of how differential weathering can shape landscape.
Differential erosion occurs when a geologic area was formed of both soft and weak rocks rocks, are harder, more resistant, rocks, weak rocks wear away first leaving behind knobs and cliffs of more resistant rocks.
physical weathering is weathering that you can reverse and chemical weathering is where you can' reverse it.
A type of Chemical weathering that happens when water interacts with minerals.
Mechanical Weathering
Physical weathering is due to: rocks hitting other rocks causing them to break up from the action of frost and ice the action of wind or waves or running water the action of plants. Chemical weathering changes the composition of the rock and is due to: water dissolving minerals in the rock oxidation of metals in the rock
Why is weathering important to life on land?

stuff
yes you can
differential weathering water wears away some areas but not all
Differential weathering is the difference in degree of discoloration, disintegration, etc., of rocks of different kinds exposed to the same environment. Quartz deposits in basaltic flows will weather slower than the surrounding rock, while being exposed to the same forces of weathering.
Differential weathering
Rock type, mineral content, degree of compaction, location of rock, rate & consistency of weathering agent.

Tafoni, also called 'honeycomb weathering' are a group of significant pits formed in the surface of a rock. Very common in coastal areas, where the regular wet-dry cycles are obvious. Caused by differential weathering of the rock, and the 'lands' between the pits are often quite thin and lacy in appearance. The presence of salt is thought to be an important feature of this type of weathering.
