Island Hot Spots

What is molten rock that has formed deep within the Earth?

• Hot Spot
• Magma
• Lava
• Volcano

Vocanoes are found...

• on land
• under water
• on islands
• all of the above

Hotspots are volcanoes that form...

• at convergent plate boundaries.

• at divergent plate boundaries.

• at transform plate boundaries.

• in the middle of a tectonic plate.

Hotspots form because...

• a mantle plume weakens Earth's crust.

• water is pushed up to Earth's surface

• a mantle plume strengthens Earth's crust.

The cross section below displays the movement of an oceanic tectonic plate over a hotspot, resulting in the formation of a chain of volcanos labeled A, B, C and D. The geological age of volcano C is shown. What are the most likely ages of volcanos B and D?

• B is 5 million years old and D is 12 million years old

• B is 2 million years old and D is 6 million years old

• B is 9 million years old and D is 9 million years old

• B is 10 million years old and D is 4 million years old

How did the Hawaiian islands form?

• at an ocean-ocean convergent boudary

• at a hotspot

• at a ocean-continental convergent boundary

• at an oceanic divergent boundary

Based on the map chose the answer that best describes the age of the hawaiian islands.

• The big island of hawaii is further from the hotspot and the oldest island.

• Oahu is further from the hotspot and the youngest island.

• The big island of hawaii is closest to the hotspot and the youngest island.

• Oahu is closest to the the hotspot and the oldest island.
