• Density contrast

• Temperature

• Viscosity

• All of the above

What process occurs if there are formation and movement of magma under the earth’s crust?

• flux melting

• partial melting

• heat transfer

• decompression melting

What term should be used to describe a semi-liquid hot molten rock located beneath the Earth?

• lava

• magma

• rocks

• sand

In what part of the earth does magmatism happen?

• asthenosphere

• earth’s crust

• earth’s core

• lithosphere

What do you call the semi-liquid hot molten rocks found on the surface of earth once the volcano erupts?

• lava

• sand

• rocks

• magma

During partial melting of magma, where does decompression melting take place?

• subduction zone

• mid-ocean ridge

• convergent boundary

• all of these

Which of the following DOES NOT belong to the group?

• dolomite

• feldspar

• mica

• quartz

Why does foliation or lineation happen among deformed rocks? It is because of _____?

• pressure and recrystallization of rocks

• eruption of magma from the mantle to the crust

• increase in temperature in the surrounding area

• increase in volume of water as the rocks’ depth increases

How do temperature and pressure affect metamorphism?

• Pressure and temperature increase as you go up to the crust.

• The deeper the rock depth, the higher the pressure and temperature.

• Foliation happens as there is an increase in the pressure and temperature.

• Magma cannot bake the surrounding rocks due to the difference in temperature.

King is walking down the river when she sees an unknown metamorphic rock. Which of the following characteristic can BE SThelph to immediately identify the type of metamorphism that the rock underwent using a magnifying glass?

• foliation

• grain size

• name of the rock

• kind of mineral present in the rock
