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

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...

• magma is pushed to the surface at a plate boundary.

• a mantle plume weakens Earth's crust.

• water is pushed up to Earth's surface

• a mantle plume strengthens Earth's crust.

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

This image shows the hawaiian island change. Hawaii is currently the tallest island and is still an active volcano. Based on the map chose the answer that best explains the age of the islands.

• The further the islands are from Hawaii the younger the island is.

• Hawaii is the youngest island because it is currently on top of the hotspot.

• Hawaii is the oldest island because it is closest to the hotspot.

• Ohau is younger than the big island because it is further from the hot spot.

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.
