Warm Up: Hot Spots

The diagram shows a chain of hotspot volcanoes in an ocean. The arrow shows the direction of motion of the tectonic plate. What can a geologist assume about the ages of the volcanic rocks that form the islands?

• 1. All of the rocks are about the same age.

• 1. The age of the volcanic islands increase in age from Volcano A to Volcano D.

• 1. The age of the volcanic islands increase in age from Volcano D to Volcano A

• 1. There is a random distribution of the various ages of the volcanic islands.

The orientation of a hotspot track can be used to infer:

• 1. The direction of motion of a tectonic plate

• 1. Where strong earthquakes are likely to occur

• 1. Where a new plate boundary is likely to form in the near future

• 1. The approximate depth inside the Earth where the hotspot magma originates

On Earth, hotspot volcanoes tend not to grow very large because:

• 1. The lava they produce is very dense

• 1. Hotspots do not produce much magma

• 1. The hotspot moves steadily beneath the lithosphere

• 1. The lithosphere moves while the hotspot stays in one place.

A scientist wants to conduct field work to learn more about Hot Spots. Where is the best place for the scientist to study?

• A. India

• B. Australia

• C. Africa

• D. Hawaii

The 2 main areas that magma rises to the surface from inside Earth are:

• Spreading Centers (divergent boundaries) and mantle plumes

• Convergent Boundaries and Hot Spots

• Volcanic gases and seismic activity

• Earth's core and asthenosphere

9) Where are earthquakes MOST LIKELY to occur?

• close to the equator

• along coastal regions

• close to the center of tectonic plates

• along the boundaries of tectonic plates
