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

metamorphism

faulting

brittle deformation

rotation

Explanation / Answer

21. a=mrtamorphism
In geology the term foliation refers to the repetitive layering in the metamorphic rocks.Tectonic foilation occure due to differences in pressure.

22. c=strain
It is also called deformation. Strain is the change in the shape that a rock undergo when it is induced by stress

23. d=divergent and convergent
Normal fault mostly occurs at a divergent boundary whereas reverse fault occurs at convergent boundary

24.c=isostasy
It is the state of gravitational equilibrium between crust and mantle
