Volcanoes practice flashcard

Front

What is a shield volcano?

Back

A shield volcano is a type of volcano characterized by its broad, gently sloping sides, formed primarily by the eruption of low-viscosity lava that can flow long distances.

Front

What is a stratovolcano?

Back

A stratovolcano, also known as a composite volcano, is characterized by its steep, conical shape and is formed from alternating layers of lava flow, ash, and other volcanic debris.

Front

What is a cinder cone volcano?

Back

A cinder cone volcano is the simplest type of volcano, formed from the accumulation of volcanic debris, such as cinders and ash, around a single vent.

Front

What type of material primarily forms shield volcanoes?

Back

Shield volcanoes are primarily formed from low-viscosity lava that flows easily.

Front

What type of material primarily forms stratovolcanoes?

Back

Stratovolcanoes are primarily formed from more viscous lava, ash, and other volcanic materials.

Front

What is the main difference between shield and stratovolcanoes?

Back

The main difference is in their shape and eruption style: shield volcanoes have gentle slopes and produce fluid lava flows, while stratovolcanoes have steeper slopes and produce more explosive eruptions.

Front

What is volcanic ash?

Back

Volcanic ash consists of tiny fragments of rock and glass created during explosive volcanic eruptions.

Front

What are volcanic cinders?

Back

Volcanic cinders are small, solid fragments of lava that are ejected during a volcanic eruption and can accumulate around the vent to form cinder cone volcanoes.

Front

What is lava?

Back

Lava is molten rock that erupts from a volcano and flows onto the Earth's surface.

Front

What is the eruption style of shield volcanoes?

Back

Shield volcanoes typically have non-explosive eruptions, allowing lava to flow smoothly and create broad, shield-like shapes.
