Types of Volcanoes

Front

What is a Shield Volcano?

Back

A type of volcano that forms due to a series of quiet eruptions, characterized by broad, gently sloping sides.

Front

What is a Composite Volcano?

Back

A type of volcano that forms from alternating quiet and explosive eruptions, resulting in layers of lava and ash.

Front

What is a Cinder Cone Volcano?

Back

A type of volcano formed from the accumulation of volcanic debris, typically having steep sides and a bowl-shaped crater.

Front

What is Viscosity in relation to lava?

Back

Viscosity refers to the thickness or resistance to flow of lava; higher silica content increases viscosity.

Front

What is Magma?

Back

Molten rock that is found beneath the Earth's crust.

Front

What is Lava?

Back

Molten rock that erupts onto the Earth's surface.

Front

What type of eruptions do Shield Volcanoes have?

Back

Quiet eruptions that produce low-viscosity lava.

Front

What type of eruptions do Composite Volcanoes have?

Back

Alternating explosive and quiet eruptions.

Front

What is the main characteristic of Cinder Cone Volcanoes?

Back

They are built from volcanic ash and debris, forming steep slopes.

Front

How does silica content affect lava?

Back

Higher silica content increases the viscosity of lava, making it thicker.
