100
the physical disintegration of rock into smaller fragments
What is mechanical weathering
200
a natural geological process that makes minerals, rocks and landforms

300
the mechanical breakup of rock caused by the expansion of freezing water in cracks and crevices
What is frost wedging
300
a layer in a soil profile
What is horizon
300
a region where glacial melt has created streams that dry up and deposit sediment
