• Places on the earth's surface that are directly above a column of rising magma

• Portable Wi-Fi

• A vent or opening in the earth's crust, through which magma, steam, ashes, and gases are forced

• a place in rock where magma gathers

Multiple Choice

Which is not a way volcanoes form?

• Above hotspots

• At divergent boundaries

• At transform boundaries

• At subduction zones

Multiple Select

What causes volcanoes to form at subduction zones?

• Pressure brings magma and gas to the surface

• subducted plate heats up and rock melts

• Magma escapes through cracks and weak spots

• gases are released

Multiple Choice

How do volcanoes form at divergent boundaries?

• The plates separate,

  Magma rises,

  Magma cools from the ocean forming rock

• Magma fills a magma chamber,

  pressure builds up,

  magma escapes through cracks and weak spots

• Subducted plate heats up,

  rocks melt,

  gases are released.

  Pressure brings magma and gas to the surface.

Multiple Choice

How does God use volcanoes to sustain his creation?
