What type of volcano is likely to form from magma with low silica and low gas content?

Back

Shield Volcano

Front

Where are most volcanoes located?

Back

At tectonic plate boundaries

Front

How does magma move from the mantle to the surface of the Earth?

Front

What is the primary composition of magma?

Back

Magma is primarily composed of molten rock, gases, and crystals.

Front

What is a cinder cone volcano?

Back

A steep, conical hill formed from volcanic ash and cinders.

Front

What is the difference between a shield volcano and a composite volcano?

Back

Shield volcanoes have gentle slopes and are formed by low-viscosity lava, while composite volcanoes have steeper slopes and are formed by more viscous lava.

Front

What is viscosity in relation to magma?

Back

Viscosity refers to the thickness or resistance to flow of magma.

Front

What are tectonic plate boundaries?

Back

Regions where two tectonic plates meet, often leading to volcanic activity.
