crust

Answer 4

you sure

Answer 5

Yes, I am sure. Physical weathering occurs primarily in the Earth's crust, where rocks are exposed to various processes such as freeze-thaw cycles, temperature changes, abrasion, and pressure changes that cause them to break down into smaller fragments.

Answer 6

Which is the last stage of physical weathering in rocks? (1 point)

Answer 7

sand

Answer 8

Answer 9

I apologize for the confusion. The last stage of physical weathering in rocks is the formation of sand. Through continual weathering processes such as erosion, abrasion, and the breakdown of rocks into smaller fragments, larger rocks eventually break down into smaller particles, eventually forming sand.

Answer 13

I'm sorry if my response was not clear. When a rock undergoes frost wedging, it must have a crack present. Frost wedging occurs when water enters a crack in the rock, freezes, and expands, which breaks the rock apart. The presence of a crack is necessary for this weathering process to occur.
