Forms of Volcanoes

A volcano’s form depends on the type of eruption— whether it is the result of a quiet or an explosive eruption and the type of ________ it is made of—basaltic, granitic, or andesitic (intermediate).

________ volcanoes are generally cone-shaped with concave slopes.

________ volcanoes are found mostly where Earth’s plates come together and one plate slides below the other.

A ________ volcano is a mountain with broad, gently sloping sides and a nearly circular base.

Because of their explosive nature, ________ volcanoes are potentially dangerous to humans and the environment.

When this cycle of lava that oozes downslope before solidifying and tephra is repeated over and over in alternating layers, a ________ volcano is formed.

________ volcanoes often form on or very near larger volcanoes.

Mauna Loa is a ________ volcano.

_____ ___ is a shield volcano.

Quiet eruptions of basaltic lava spread out in flat layers. The buildup of these layers forms a broad volcano with gently sloping sides called a ________ volcano.

When tephra falls back to Earth, it piles up around the vent and it forms a steep-sided, loosely packed ________ volcano.

________ volcanoes are formed of layers of hardened chunks of lava from violent eruptions alternating with layers of lava.

________ volcanoes form when layers of lava accumulate during nonexplosive eruptions.

________ volcanoes are the largest type of volcano.

Soufrière Hills volcano is an example of a ________ volcano.
