When molten rock undergoes crystallization above ground, what type of rock results?

• Intrusive igneous rock

• Extrusive igneous rock

• Metamorphic rock

• Sedimentary rock

What combination of processes can transform a metamorphic rock to sediments?

• Erosion, crystallization, and melting.

• Heating, pressure, and lithification.

• Melting, crystallization, and compaction.

• Exposure, weathering, and erosion.

What sequence of events could lead to magma becoming soil?

• Erosion and deposition followed by exposure to heat and pressure.

• Compression and lithification followed by erosion and deposition.

• Crystallization followed by exposure and weathering.

• Crystallization followed by increased heat and pressure.

Which of the following rock types form from placing other rocks under heat and pressure?

• Sedimentary rock

• Metamorphic rock

• Intrusive igneous rock

• Extrusive igneous rock

According to the rock cycle, which of the following transitions are possible? Assume an unlimited number of steps.

• An intrusive igneous rock becomes a sedimentary rock.

• A sedimentary rock becomes soil.

• A metamorphic rock becomes an extrusive igneous rock.

• All of the above are possible.

What kind of boundary or zone is shown in the image above?

• Subduction zone

• Divergent boundary

• Collision zone

• Transform boundary

Which type of plate boundary or zone would be most likely to lead to above-ground volcanic activity?

• Subduction zone

• Divergent boundary

• Collision zone

• Transform boundary

Which boundary or zone adds new material to the lithosphere (the hard outer crust of the Earth)?

• Subduction zone

• Divergent boundary

• Collision zone

• Transform boundary

In what way does a transform boundary differ from the other boundary types?

• Transform boundaries are always found on the ocean floor.

• Transform boundaries can result in volcanic activity.

• At a transform boundary, one plate slides beneath the other.

• At a transform boundary, the plates move in a direction that is parallel to the boundary line.

The highest mountains in the world are the Himalayas, at the border between the Indian and Eurasian plates. The Himalayas formed in a ________________.
