Other than Hawaii & Alaska, Washington's Mount St.

Question

Helens has the highest probability out of all U.S. volcanoes to erupt in the future.

true or false

Answer 1

True. Mount St. Helens in Washington State is considered one of the most active volcanoes in the United States, with a high probability of future eruptions compared to other volcanoes on the mainland. It is closely monitored for seismic and volcanic activity.

Answer 2

Composite volcanoes get their symmetrical shape due to:
a. over a period of time & because of multiple eruptions, an accumulation of explosive matter & viscous flowing lava.

b. Composite volcanoes don't have symmetrical shapes because they can have multiple channels which, when they explode, will ruin the volcano's symmetry.

Answer 3

The correct answer is:

a. over a period of time & because of multiple eruptions, an accumulation of explosive matter & viscous flowing lava.

Composite volcanoes, also known as stratovolcanoes, are characterized by their symmetrical shape due to the alternating layers of lava flow, volcanic ash, and other volcanic debris that accumulate from successive eruptions. This layering contributes to their steep profiles.

Answer 4

What are the three states (not types) of volcanoes?
(Choose three)
a. cinder cone
b. dome
c. dormant
d. shield
e. active
f. strata or composite
g. extinct

Answer 5

The three states (or conditions) of volcanoes are:

c. dormant
e. active
g. extinct

These terms refer to the current activity status of a volcano. An active volcano is currently erupting or shows signs of erupting in the near future, a dormant volcano is not currently erupting but could do so in the future, and an extinct volcano is not expected to erupt again.
