Prentice Hall Earth Science Volcanoes Chapter 7 Quiz

What are the three main types of volcanoes?

• hot volcanoes, cold volcanoes, and lukewarm volcanoes

• big volcanoes, medium volcanoes, and small volcanoes

• shield volcanoes, cinder cone volcanoes, and composite volcanoes

• round volcanoes, square volcanoes, and triangular volcanoes

Explain the difference between shield, cinder cone, and composite volcanoes.

• The main difference between shield, cinder cone, and composite volcanoes lies in their shape, size, and the type of materials they are formed from.

• The difference is in the color of the lava they produce

• They all have the same shape and size

• They are all formed from the same type of materials

What are the different types of volcanic eruptions?

• Effusive, explosive, and phreatic eruptions

• Fast, slow, and medium eruptions

• Quiet, loud, and silent eruptions

• Hot, cold, and warm eruptions

Describe the characteristics of a Hawaiian eruption and a Plinian eruption.

• A Hawaiian eruption is characterized by highly explosive eruptions and the formation of steep-sided stratovolcanoes.

• A Hawaiian eruption is characterized by high viscosity lava and the formation of steep-sided stratovolcanoes.

• A Hawaiian eruption is characterized by low viscosity lava, gentle eruptions, and the formation of shield volcanoes. A Plinian eruption, on the other hand, is characterized by highly explosive eruptions, high viscosity lava, and the formation of steep-sided stratovolcanoes.

• A Plinian eruption is characterized by low viscosity lava and gentle eruptions.

What are some of the hazards associated with volcanic eruptions?

• Snowstorms, hail, sleet

• Earthquakes, hurricanes, tornadoes

• Drought, wildfires, heatwaves

• Lava flows, ashfall, pyroclastic flows, lahars, and volcanic gases

Explain the potential dangers of pyroclastic flows and lahars.

• Pyroclastic flows and lahars only affect the wildlife around the volcano

• Pyroclastic flows and lahars can cause widespread destruction and loss of life in areas surrounding a volcano.

• Pyroclastic flows and lahars are harmless and do not pose any danger

• Pyroclastic flows and lahars have no impact on the surrounding areas

What are some of the landforms created by volcanic activity?

• Islands, peninsulas, and plains

• Mountains, rivers, and lakes

• Volcanoes, lava plateaus, and calderas

• Canyons, deserts, and glaciers

Describe the formation of calderas and volcanic islands.

• Calderas are formed by the erosion of rock, and volcanic islands are formed by the movement of glaciers.

• Calderas are formed by the cooling of lava, and volcanic islands are formed by the impact of meteorites.

• Calderas are formed by the collapse of a volcano into the emptied magma chamber, and volcanic islands are formed by the buildup of layers of lava from underwater volcanoes.

• Calderas are formed by the eruption of a volcano, and volcanic islands are formed by the shifting of tectonic plates.

How do scientists monitor volcanic activity?

• Using seismographs, gas sensors, satellite imagery, and ground deformation measurements.

• Using weather balloons and barometers

• By observing the color of the sky

• Measuring the temperature of nearby bodies of water

Explain the use of seismographs and gas sensors in monitoring volcanic eruptions.

• Seismographs detect volcanic eruptions and gas sensors monitor changes in gas emissions.

• Seismographs detect changes in atmospheric pressure and gas sensors monitor seismic waves.

• Seismographs detect changes in gas emissions and gas sensors monitor seismic waves.

• Seismographs detect seismic waves and gas sensors monitor changes in gas emissions.
