Misfit river/streams. We can see that I the uplands that there are rivers in the bottom of the u shaped valley. This is caused by glacier when the were moving. This water inside The Valley is the melt water from glaciers.
What weathering process affect the uplands
Freeze thaw weathering affects the uplands. As well as land slide and rockfalls.
What weathering process affects the lowlands.
The lowland is affected by biological, physical and chemical weathering
What is freeze thaw weathering?
It is when water fills up in cracks. At night the cracks freeze up and overtime the crack will expand by 10%. This process will repeat over many years until the the cracks falls apart.
