Question

what is the main cause of earthquakes? (1 point)
movement of ocean currents
erosion of soil
movement of tectonic plates
melting glaciers
which process in the rock cycle transforms sedimentary rock into metamorphic rock? (1 point)
weathering
heat and pressure
melting
cementation

Explanation:

Earthquakes mainly occur due to the movement of tectonic plates which release energy in the Earth's crust. In the rock - cycle, sedimentary rock is transformed into metamorphic rock by heat and pressure, which cause physical and chemical changes in the rock.

Answer:

1. C. Movement of tectonic plates
2. B. Heat and pressure
