Low viscosity, low gas and silica content; found in oceanic crust.

Intermediate viscosity, gas, and silica content; associated with subduction zones.

High viscosity, high gas and silica content; found in continental crust.

A measure of a fluid's resistance to flow; higher means thicker.

Refers to the amount of dissolved gases in magma; affects explosiveness.

The proportion of silicon dioxide in magma; influences viscosity and behavior.

The arrangement of magma types from least to most explosive: Basaltic, Andesitic, Rhyolitic.

Regions where one tectonic plate sinks under another, often leading to andesitic magma formation.

A volcano that is currently erupting or shows signs of erupting soon.

A volcano that has not erupted in a long time and shows no signs of future activity.

Different categories based on the eruption's activity and characteristics.

A mixture of rock fragments, glass particles, and minerals released during an eruption.

Molten rock beneath the Earth's surface, rich in silicate.

An eruption caused by the interaction of magma and water, leading to explosive activity.

Higher temperatures in magma result in lower viscosity, while lower temperatures increase viscosity.

Risks from volcanic activity threatening people and property.

Fragmented volcanic debris ejected into the atmosphere during eruptions.

A greenhouse gas released during volcanic eruptions that contributes to global warming.

A gas emitted by volcanoes that can cause cooling and air pollution.

Pulverized rocks and debris that fall to the ground after a volcanic eruption.

A mixture of water, molten rocks, and debris flowing down the volcano's side.

Streams of molten rock and debris emitted during a volcanic eruption.

Fast-moving hot mixtures of gas, ash, and molten rocks moving away from a volcano.

A large underground pool of molten rock found beneath the surface, where magma accumulates before an eruption.

The process where dissolved gases in magma form bubbles as pressure decreases during magma ascent, leading to potential eruptions.

The lowering of confining pressure on magma as it rises, promoting bubble formation through vesiculation.

The process where cooling magma forms crystals, increasing vapor pressure in residual liquid, contributing to vesiculation.

Eruptions characterized by violent outbursts of magma due to high gas content and pressure, dependent on the magma's composition.

Lavas with low viscosity that release dissolved gases easily.

Gaseous phase of water released by volcanic eruptions.

The process of throwing out molten materials and gases from a volcano.

A hot spring that intermittently sends water and steam into the air.

An opening containing hot water compared to surrounding areas.

Magma from melting mantle, low in silicate and rich in iron and magnesium.

Sudden releases of energy causing shockwaves and destructive effects.

A mixture of water and loose soil that flows down a slope.

A way to evaluate understanding or knowledge through tests or quizzes.

A specific section or unit within a course or program, focusing on a topic.

The government body responsible for managing public education systems.

Sources of information or materials used for research and study.
