Why are island chains formed in a line?

Because the tectonic plate moves over a stationary hotspot

What is the next phase of island chain formation?

Magma breaks through the crust and builds up to create a volcanic island.

What makes a hotspot different from most volcanic activity?

It occurs away from plate boundaries

Where is a hotspot located?

Beneath the crust, under a tectonic plate

What is a lava plume?

A heated portion of mantle rising toward the crust

14. What happens to the older islands in the chain?

They are worn down by wind and water erosion

What is the next phase of island chain formation?

Tectonic plate movement takes the island away from the hotspot.

Why does a volcanic island eventually stop erupting?

The tectonic plate moves it away from the hotspot

What eventually happens to the original volcanic island in the chain?

It moves away from the hotspot and becomes inactive

What is the first phase in the formation of a volcanic island chain?

A lava plume from the mantle creates a hotspot in the crust.

How does a volcanic island form?

From lava building up over time

What is the next phase of island chain formation?

A second volcano forms over the hotspot and the island chain appears.

Farthest from the hotspot
Directly above the hotspot
6
What makes a hotspot different from most volcanic activity?
It occurs away from plate boundaries

7
1. What causes a lava plume to rise toward the Earth's crust?
Solar energy
Ocean currents
Plate collisions
Heat from the Earth's core
8

On the ocean surface
9
What is a lava plume?
A heated portion of mantle rising toward the crust
A steam vent in the ocean
An underwater mountain range
A type of earthquake
10
14. What happens to the older islands in the chain?
They are destroyed by earthquakes
They keep getting bigger due to volcanic activity
