Volcano Review

If geologists detect small earthquakes near a volcano what can they infer about the volcano?

In which location would you most likely find volcanoes?

Tall cone shaped mountains in which layers of lava alternate with layers of ash are called

When many layers of thin, runny lava build up a high, level area, the result is a

Larger, cone shaped mountain that alternates between quiet and explosive eruptions

A volcano that has not erupted in 100's of years but may erupt again without warning

Main factor that accounts for the difference between quiet and explosive volcanic eruption is

The outer boundary of the Pacific Plate is nicknamed

Before lava reaches the surface, the molten material is called

The huge hole left by the collapse of a volcanic mountain is called a

Forms Subduction Zones - Ocean Plate vs Ocean Plate or Ocean Plate vs Continental Plate

A volcano that has not erupted in 1,000 of years and probably wont erupt again...But it Could!

Steep, cone shaped hill or mountain with explosive eruptions of ash, cinders, and bombs

The main hazard from a quiet volcanic eruption is

An area where magma from deep within the mantle melts through the crust. Ex: Hawaiian Islands

The majority of Volcanoes on earth are located around the edge of what tectonic plate

A volcano that is currently erupting or showing signs that it may erupt

When magma hardens in a volcano's pipe, the result will eventually be a land form called a

What provides the force that causes magma to erupt to the surface?

A volcano with wide, sloping mountain and quiet eruptions, gradually building lava layers

Divergent boundaries form
