Q

Classification of A Volcano According to Eruption:

A

Active, Dormant, Inactive/Extinct

32
Q

These volcanoes have not had any eruption in the past 10 000 years and are expected not to erupt anymore in the future.

A

Extinct / Inactive

33
Q

they have erupted at least once in the last past 10 000 years and are likely to erupt again

Active

34
Q

active but not erupting; however they are expected to erupt anytime soon.

A

Dormant

35
Q

Kinds of Eruptions
Can be classified as either

A

effusive or explosive.

36
Q

Involve the outpouring of basaltic magma that is relatively low in viscosity and low in gas content.

A

Effusive eruptions

37
Q

involve magma of high viscosity and high gas content.

A

Explosive eruptions

38
Q

Driven by steam due to rapid heating beneath a volcano.

A

Phreatic
