Front

What is the explosiveness of magma with intermediate viscosity and high gas content?

Back

Somewhat Explosive

Front

What is the explosiveness of mafic magma with low viscosity and high gas content?

Back

Somewhat Explosive

Front

Define Caldera.

Back

A crater made by the collapse of a volcanic cone during a huge eruption.

Front

What type of lava produces wide and shallow sloped volcanoes?

Back

Mafic-Low Viscosity.

Front

Define Landslide.

Back

A mass of rocks and earth moving suddenly and quickly down a slope.

Front

What are the characteristics of mafic lava?

Back

Mafic lava has low viscosity and is typically associated with less explosive eruptions.

Front

What is the relationship between gas content and explosiveness in volcanic eruptions?

Back

Higher gas content generally increases the explosiveness of a volcanic eruption.

Front

What geological feature is formed by the collapse of a volcano after a major eruption?

Back

A caldera.

Front

What type of volcanic eruption is characterized by the ejection of ash, gas, and lava?

Back

Explosive eruption.

Front

What is the primary difference between mafic and felsic lava?

Back

Mafic lava has lower viscosity and is less explosive, while felsic lava has higher viscosity and is more explosive.
