Volcanic Hotspots Quiz

What is a hotspot?

• A particularly cold part of the mantle

• A particularly hot part of the mantle

• A region with frequent tornadoes

• A region with high humidity levels

What causes volcanic hotspots?

• Collision of tectonic plates

• Subduction of tectonic plates

• Movement of magma from the Earth's mantle

• Erosion by water and wind

What happens when rocks melt due to the heat of a hotspot?

• They form icebergs

• They produce magma

• They turn into sedimentary rocks

• They become solid crystals

Where are volcanic hotspots commonly found?

• Along subduction zones

• At divergent plate boundaries

• At the centre of tectonic plates

• Near transform faults

How does magma from a hotspot form a volcano?

• It flows into the ocean

• It cools rapidly and forms mountains

• It rises up through the crust and erupts onto the surface

• It remains trapped underground indefinitely

What happens to a volcano as the tectonic plate moves away from the hotspot?

• It becomes more active

• It remains stationary

• It becomes inactive

• It collapses into the mantle

How is the age of volcano in a hotspot chain impacted by their distance from the hotspot?

• The oldest volcanoes are closest to the hotspot

• The oldest volcanoes are furthest from the hotspot

• Age and distance from the hotspot are unrelated

• All volcanoes in a chain are the same age

How do volcanic hotspots contribute to the formation of island chains?

• By causing earthquakes

• By melting ice caps

• By erupting explosively

• By producing successive volcanic eruptions as tectonic plates move

Which of the following is an example of a volcanic island chain created by a hotspot?

• Mount Everest

• Rocky Mountains

• Hawaiian Islands

• Alps

Most volcanoes and earthquakes are found along plate boundaries. There are a number of volcanoes that sit in the middle of plates. These volcanoes have formed above a hot spot - a single plume of rising mantle. Hot spots are found in the ocean, and on continents.
