19
Which of the following is the outermost layer of the Earth?
crust
20

convection current
21
What process occurs if there are formation and movement of magma under the earth's crust?
magmatism
22
What term should be used to describe a semi-liquid hot molten rocks located beneath the Earth?

both b and c
33
During partial melting of magma, where does flux melting take place?
subduction zone
34
Conduction in mantle happens when heat is transferred from hotter molten rocks to the Earth's cold crust. What process is being described?
heat transfer
35
How do temperature and pressure affect metamorphism?
The deeper the rock depth, the higher the pressure and temperature.
