QUESTION 25

Mount Marshak towers above the landscape at 5.3 km tall. The rate of uplift at Mount Marshak is 1.3 mm/yr and the rate of erosion is 1.5 mm/yr. How tall will Mount Marshak be after a million years, assuming everything remains constant?

5.5 km

7.3 km

5.1 km

3.3 km

brittle deformation

plastic deformation

shear strain

rotation

Explanation / Answer

1. Brittle Deformation. The breaking of rock when subjected to the stress is know as the brittle deformation.

2. High Temperature. The hot rock is more ductile than cold rock.

3. High Temperature. The hot rock is more ductile than cold rock.

4. Italian Alps

5. warm, ductile crust under compression. The more ductile rock is easy to bend and compression will help in bending.
