The San Andreas Fault in California is a strike-slip fault. Which of these statements best describes a strike-slip fault?

• Two fault blocks move in the same direction.

• One fault block moves up relative to the other.

• One fault block moves down relative to the other.

• Two fault blocks move past each other horizontally.

What happens to rocks during deformation?

• Rocks become minerals.

• Rocks change shape and size.

• Rocks change into metal ores.

What is the relationship between magma and lava?

• Magma is lava that has cooled to form solid rock.

• Lava is magma that has cooled to form solid rock.

• Magma is lava that has reached Earth’s surface.

• Lava is magma that has reached Earth’s surface.

A hot spot is a volcanically active area that is usually located far from the edge of a tectonic plate. A volcanic island can form over a hot spot. Which would you expect to find beneath the hot spot?

• a rift zone

• a mantle plume

• a divergent boundary

• a convergent boundary

How does pyroclastic material differ from lava?

• Unlike lava, pyroclastic material erupts onto Earth’s surface.

• Unlike lava, pyroclastic material erupts from shield volcanoes.

• Unlike lava, pyroclastic material is associated with explosive eruptions.

• Unlike lava, pyroclastic material is associated with nonviolent eruptions.
