Volcanoes Earth Science Chapter 8

A volcano that emits mostly lava in quiet eruptions.

A liquid emission of volcanoes that moves slowly and causes few deaths.

According to the USGS, a volcano that has not erupted in historical times but is not significantly eroded is called a(n)

Tiny, angular glassy fragments.

The geothermal gradient is the highest in the

What kind of volcanoes would a young-earth geologist consider active on the basis of a biblical view of Earth's history

Most active volcanoes in the world exist near convergent tectonic plate boundaries.

An enlarged depression that is caused by an explosion or the collapse of a volcanic cone.

Sills and dikes are products of intrusive volcanism.

Volcanoes are made of igneous rock.

Old earth geologists believe all volcanoes have erupted with historical time-this means they classify them all as active

Pyroclastic flow is made up of both solid particles & gases-can cause burning & suffocation.

Which of the following statements describes a typical young-earth geologist's view of volcanoes?

The term igneous rock is used to describe lava that has cooled and solidified on the ground.

Many more deaths during eruptions happen due to flowing lava than pyroclastic flows.

A good example of a hydrothermal circuit is

Which of the following volcano types takes up the most land area?

Secular geologists believe most of earth's heat comes from the big bang.

Streamlined mass of ejected lava that has solidified in flight.

A rapid downhill movement of hot, solid, volcanic particles suspended in steam is

I need to know on the test why geysers and hot springs produce distinctive mineral deposits.

The largest volcanic eruptions in the history of the earth were probably similar to

Wall-like igneous intrusions are called

Volcanoes can be classified by age, structure, and activity.

Flood basalts or basalt traps are

Solid emissions can include ash, cinders, blocks, & bombs-this can lead to suffocation & or injury/death if it strikes
