A mixture of volcanic debris and water that flows rapidly downhill during volcanic eruptions.

Smooth, rope-like lava flows often formed by low viscosity basaltic lava.

Lava that cools and forms rounded, pillow-like shapes underwater.

Volcanic eruptions can have both short-term and long-term effects on the Earth, including temporary cooling due to gas emissions and long-term changes to landscapes.

Volcanic eruptions release gases, solids, and liquids that can be dangerous but also beneficial, playing a role in shaping landscapes and enriching soil.

Materials, gases, and molten rock expelled during volcanic eruptions due to pressure changes and chemical reactions.

Volcanic emissions are classified into three main categories: gases, solids, and liquids.

The most abundant volcanic gas, making up 70-90% of total emissions. It's responsible for cloud formations and volcanic rainfall.

Greenhouse gases that accumulate in the atmosphere and can cause global cooling and suffocation.

Reacts with water vapor to form sulfuric acid causing acid rain.

Fine particles of crushed rock and glass that can travel far distances in ash clouds. They contribute to environmental damage and can cause respiratory problems.

Molten rock expelled from volcanoes during eruptions. It can reach temperatures of 700 degrees Celsius.

Solid materials ejected from volcanoes during eruptions, also known as pyroclastic materials. They range in size from ash to boulders.
