Answer
- True
- False
Question 2
Question
Volcanic belts form along the boundaries of Earth's plates.
Answer
- True
- False
Question 3
Question
At plate boundaries, huge pieces of the crust diverge (pull apart) or converge (push together). As a result, the crust often fractures, allowing magma to reach the surface.
Answer
- True
- False
Question 4
Question
Most volcanoes form along diverging plate boundaries such as mid-ocean ridges and along converging plate boundaries where subduction takes place.
Answer
- True
- False
Question 5
Question
Along the _____________________, lava pours out of cracks in the ocean floor, gradually building _______________________.
Answer
-
Eastern seaboard, new states
-
rift valley, new mountains
Question 6
Question
Many volcanoes form near ________________ plate boundaries where oceanic plates return to the _____________________.
Answer
-
converging, mantle
-
diverging, core
-
converging, core
-
diverging, mantle
Question 7
Question
Volcanoes often form where:
Answer
-
two oceanic plates collide
-
an oceanic plate collides with a continental plate
-
near boundaries where two oceanic plates collide
-
near converging plate boundaries where oceanic plates return to the mantle
Question 8
Question
Through subduction, the older, denser plate sinks beneath a deep-ocean trench into the mantle. Some of the rock above the subducting plate melts and forms magma.
Answer
- True
- False
Question 9
Question
Because magma is more dense than the surrounding rock, it rises toward the surface.
Answer
- True

Question 10
Question

tsunamis
-
earthquakes
-
volcanoes
Question 11
Question

ring of fire
-
island arc
-
earthquake belt

Answer
-
buried
-
subducted
-
elevated
Question 13
Question
Some volcanoes result from "hot spots" in Earth's mantle.
Answer
- True
- False
Question 14
Question
A volcano forms above a hot spot when water erupts through the crust and reaches the surface.
Answer
- True
- False
Question 15
Question
A hot spot in the ocean floor can gradually form a series of volcanic mountains.
Answer
- True
- False
Question 16
