Eruption Effects

Front

What is a shield volcano?

Back

A type of volcano characterized by its broad, gently sloping sides, formed by the eruption of low-viscosity lava that can flow over great distances.

Front

How do volcanoes create new land?

Back

Volcanoes create new land by erupting lava that cools and solidifies, forming new rock and landforms.

Front

What is the primary process that formed the Hawaiian Islands?

Back

Volcanic activity is the primary process that formed the Hawaiian Islands.

Front

What type of plate movement is associated with the formation of Hawaiian volcanoes?

Back

Divergent plate movement is associated with the formation of Hawaiian volcanoes.

Front

What is lava?

Back

Lava is molten rock that erupts from a volcano and solidifies upon cooling.

Front

What are the effects of volcanic eruptions on the environment?

Back

Volcanic eruptions can create new land, alter landscapes, affect climate, and impact ecosystems.

Front

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

Back

Stratovolcanoes have steeper, more conical shapes and are formed from more viscous lava, while shield volcanoes have gentle slopes and are formed from low-viscosity lava.

Front

What role do tectonic plates play in volcanic activity?

Back

Tectonic plates move and interact at their boundaries, leading to volcanic activity when they diverge, converge, or slide past each other.

Front

What is volcanic ash?

Back

Volcanic ash consists of tiny fragments of rock and glass that are ejected during a volcanic eruption.

Front

How can volcanic eruptions affect climate?

Back

Volcanic eruptions can release ash and gases into the atmosphere, which can block sunlight and lead to temporary cooling of the Earth's surface.
