Which part of Earth experiences physical weathering? (1 point)
Responses
inner core
inner core
crust
crust
mantle
mantle
outer core
None of the above. Physical weathering occurs at the Earth's surface, primarily in the crust.
The correct response is:
crust
The part of the Earth that experiences physical weathering is the crust.
Physical weathering refers to the breaking down of rocks and minerals into smaller pieces without changing their chemical composition. This can occur through various processes such as temperature changes, freeze-thaw cycles, and abrasion by wind and water. These processes mainly affect the outermost layer of the Earth, known as the crust.
To arrive at this answer, you can remember that physical weathering involves the mechanical breakdown of rocks and minerals, and this primarily occurs in the crust. Alternatively, you could use logic to eliminate the other options: the inner core is a solid metallic layer at the center of the Earth, the outer core is a liquid layer surrounding the inner core, and the mantle is a highly viscous layer between the crust and the outer core. These layers are not directly exposed to the same weathering forces as the crust.
