Reviewing Volcano Centers

What is the best definition of HOT SPOT?

• A spot where there is a active volcano.

• A particularly hot part of the mantle that causes rock to melt into magma.

• A spot underground where two magma chambers combine to make a larger volcano.

• A spot where the mantle completely melts.

Which of the following is a common instrument used to measure the inflation magma chamber under a volcano?

• Seismogram

• Elevator

• Tiltmeter

• Thermometer

Which of the following is NOT a indication of a coming volcanic eruption?

Why is it important to predict volcanic eruptions?

• In order to evacuate and prevent loss of life.

• So that scientists can be there to study the eruption.

• To warn animals to leave the area.

• So that no one is surprised.

• It has hot runny lava.

• The sides of the volcano are very steep.

• Often forms over a hot spot.

• Hawaii and Iceland are examples.

Check all of the following that are characteristics of Composite Volcanoes.

• Made of hot runny lava.

• Usually found where plates collide.

• Tall and pointed.

• Flatter at the base and steep at the summit.

Check all of the following that are characteristics of Cinder cone Volcanoes.

• The smallest of common types of volcanoes.

• Very explosive eruptions.

• Hot runny lava.

• The ejecta is mostly ash and rock fragments.

Which of the following is NOT a factor when determining Volcanic Explosivity Index.

• The volume of material ejected.

• The height of the plume of ash.

• The height of the volcano.

• How frequently the volcano erupts.

Which of the following is NOT a landform that can be created by magma moving underground.

The VEI (volcanic explosivity index) of Kilauea is a 0 (on a 0-8 scale) Why is it so low?

• Because Kilauea does not erupt very often and has a really high plume.

• Because Kilauea erupts constantly but has very little ejecta.

• Because Kilauea is a hot spot volcano.

• Because Kilauea is not very big.
