Question 1 of 18

Medal-premium 1

Select one of the following:

  • True

Question 2 of 18

Medal-premium 1

Select one of the following:

  • True
  • False

Question 3 of 18

Medal-premium 1

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.

Select one of the following:

  • True
  • False

Question 4 of 18

Medal-premium 1

Most volcanoes form along diverging plate boundaries such as mid-ocean ridges and along converging plate boundaries where subduction takes place.

Select one of the following:

  • True
  • False

Question 5 of 18

Medal-premium 1

Along the _____________________, lava pours out of cracks in the ocean floor, gradually building _______________________.

Select one of the following:

  • Eastern seaboard, new states

  • rift valley, new mountains

Question 6 of 18

Medal-premium 1

Many volcanoes form near ________________ plate boundaries where oceanic plates return to the _____________________.

Select one of the following:

  • converging, mantle

  • diverging, core

  • converging, core

  • diverging, mantle

Question 7 of 18

Medal-premium 1

Volcanoes often form where:

Select one or more of the following:

  • 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 of 18

Medal-premium 1

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.

Select one of the following:

  • True
  • False

Question 9 of 18

Medal-premium 1

Because magma is more dense than the surrounding rock, it rises toward the surface.

Select one of the following:

  • True
  • False

Question 10 of 18

Medal-premium 1

When magma breaks through the ocean floor, it creates

Select one of the following:

  • tsunamis

  • earthquakes

  • volcanoes

Question 11 of 18

Medal-premium 1

Resulting volcanoes formed along a deep ocean trench are called a

Select one of the following:

  • ring of fire

  • island arc

  • earthquake belt

Question 12 of 18

Medal-premium 1

Volcanoes occur where an oceanic plate is __________________________ beneath a continental plate.

Select one of the following:

  • buried

  • subducted

  • elevated

Question 13 of 18

Medal-premium 1

Some volcanoes result from "hot spots" in Earth's mantle.

Select one of the following:

  • True
  • False

Question 14 of 18

Medal-premium 1

A volcano forms above a hot spot when water erupts through the crust and reaches the surface.

Select one of the following:

  • True
  • False

Question 15 of 18

Medal-premium 1

A hot spot in the ocean floor can gradually form a series of volcanic mountains.

Select one of the following:

  • True
  • False

Question 16 of 18

Medal-premium 1

The _____________________ Islands formed over ______________ of years as the Pacific Plate drifted over a hot spot.

Select one of the following:

  • British

  • Hawaiian

Select one of the following:

  • True
  • False

_______________________________________ in Wyoming marks a hot spot under the North American plate.

Select one of the following:
