200
what is magma that has reached the surface of the earth?
What is lava
200
what is a string of islands created by volcanoes?
What is a island arc
200
what is an area where material from deep within the mantle rises and then melts, forming magma?
What is a hot spot
300
How does a hotspot volcanoes form?
When magma erupts through the crust and reaches the surface.
300
What is the difference between magma and lava?
Magma is underground while lava is on the surface.
300
Where are most volcanoes located?
Along diverging boundaries and converging boundaries where subduction takes place.
300
In what ways is a volcano constructive force?
Because after lava from the volcano cools it forms solid rock which build up the earths surface.
300
Many volcanoes form along _____________ and ___________ boundaries.
Converging and diverging boundaries
400
What is an island arc?
a string of islands created by volcanoes
400
What is lava?
Magma that has reached the surface of earth.
400
What is a hotspot?
An area where deep in the mantle mantle rises and then melts forming magma.

500
Name two products of hot spot volcanoes.
Yellowstone, and Hawaii
500
Name two island arcs
Japan, Aleutians, New Zealand, Indonesia, the Philippines, and the Caribbean islands
500
What volcanoes were formed by coverging boundaries.
The Andes mountains and the volcanoes of the Pacific Northwest.
500
How is a vocanoes formed at a diverging boundary?
Lava pours out of cracks in the rift valley and gradually build up a mountain.
500
How is a volcano formed at a converging boundary?
Rocks above the subducting plate will melt forming magma, which will then rise to the surface and form a volcano.
