Volcanoes

Front

What is pyroclastic material?

Back

Pyroclastic material is a type of volcanic rock that is formed when magma explodes from a volcano, resulting in a mixture of ash, pumice, and volcanic gases.

Front

Why does thick and sticky lava cause larger explosions?

Back

Thick and sticky lava moves slowly, blocking vents and trapping gases, which can lead to larger explosions.

Front

Do all volcanic eruptions impact the earth's climate?

Back

False. Not all volcanic eruptions have a significant impact on the earth's climate.

Front

What type of volcano has steep sides and erupts explosively?

Back

Composite volcanoes have steep sides and are known for their explosive eruptions.

Front

What is the main factor affecting a volcanic eruption?

Back

The composition of the magma is the main factor affecting a volcanic eruption.

Front

What is a shield volcano?

Back

A shield volcano is a type of volcano characterized by its broad, gently sloping sides and primarily non-explosive eruptions.

Front

What is the difference between magma and lava?

Back

Magma is molten rock beneath the earth's surface, while lava is magma that has erupted onto the surface.

Front

What are volcanic gases?

Back

Volcanic gases are gases emitted by a volcano, including water vapor, carbon dioxide, sulfur dioxide, and others, which can affect air quality and climate.

Front

What is a cinder cone volcano?

Back

A cinder cone volcano is a small, steep-sided volcano formed from the accumulation of volcanic debris, such as ash and cinders.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, due to tectonic plate movements.
