Hotspot Volcanoes: Formation, Locations, and Effects

Which of the following locations is known for its hotspot volcanic activity?

• The Himalayas

• The Andes

• Yellowstone National Park

• The Alps

How do hotspot volcanoes form?

• By the movement of tectonic plates

• By a plume of hot material rising from deep within the Earth's mantle

• By the melting of subducted oceanic crust

• By the collision of continental plates

What is a significant effect of hotspot volcanoes?

• Formation of new oceanic crust

• Creation of mountain ranges

• Formation of volcanic islands and seamounts

• Shifting of continental plates

The Hawaiian Islands are an example of islands formed by:

• Subduction zones

• Continental rifts

• Hotspot volcanism

• Oceanic-oceanic plate convergence

What is the primary cause of the heat that generates a volcanic hotspot?

• Friction between tectonic plates

• Radioactive decay in the Earth's core

• Solar radiation absorbed by the Earth's surface

• Heat from the Earth's core and the lower mantle

Which of the following is NOT a common effect of hotspot volcanic eruptions?

• Creation of geothermal features

• Formation of large igneous provinces

• Significant changes in global climate

• Formation of deep ocean trenches

Hotspot volcanoes are different from other volcanoes because they:

• Only erupt once and then become extinct

• Are not associated with tectonic plate boundaries

• Can only form on continental land masses

• Erupt more violently than any other type of volcano

The age of the volcanic islands in a hotspot chain typically:

• Decreases with distance from the hotspot

• Increases with distance from the hotspot

• Remains constant throughout the chain

• Is unpredictable and random

Which of the following is a long-term effect of hotspot volcanism?

• The creation of new species through evolutionary isolation

• The immediate formation of deep ocean trenches

• Rapid cooling of the Earth's atmosphere

• Decrease in sea level globally

Why do hotspot volcanoes often form chains of volcanic islands and seamounts?

• Because the hotspot remains stationary while tectonic plates move over it

• Due to the rapid movement of hotspots through the Earth's mantle

• Because of the sequential eruption of multiple hotspots in a linear pattern

• Due to the alignment of tectonic plate boundaries
