Unit 4 Lesson 4 - Volcanoes Study Game

Volcanic vents are places where magma can erupt onto Earth’s surface. Which volcanic feature forms a relatively small depression around a volcano’s vent?

• crater

• fissure

• caldera

• lava plateau

Volcanic vents are places where magma can erupt onto Earth’s surface. In some cases, these vents are long cracks in the ground. What is this type of crack in Earth’s surface called?

• crater

• fissure

• caldera

• lava plateau

Which of the following describes magma?

• solid rock

• molten rock

• volcanic ash

• volcanic ore

Alternating quiet and violent eruptions are associated with which kind of volcano?

• shield

• composite

• pyroclastic

• cinder cone

Molten material flows gently out of a fissure on Earth’s surface, then cools and hardens. This process happens again and again over geologic time. Eventually, what will form on the surface?

• caldera

• plate boundary

• magma chamber

• volcanic mountain

Which type of volcano has the steepest sides?

• shield

• composite

• pyroclastic

• cinder cone

The diagram below shows a cross section of a volcano.

From which point would molten material, ash, and dust be expelled?

• point 1

• point 2

• point 3

• point 4

What is the relationship between magma and lava?

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

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

• They are both types of solid material that spew out of a volcano.

• They are both molten rock found at different depths below Earth’s surface.

A hot spot is a volcanically active area. 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.
