Volcanic eruptions can emit a variety of materials, including lava (molten rock), ash, gases (such as water vapor, carbon dioxide, sulfur dioxide), and volcanic rocks like pumice and obsidian. These materials can have different impacts on the environment, depending on the type of eruption and the composition of the volcano.
A volcanic eruption can emit gases such as water vapor, carbon dioxide, sulfur dioxide, hydrogen sulfide, and hydrogen chloride. Other materials include ash, rock fragments, and lava. The combination of these emissions can have various impacts on the environment and human health.
The ash cloud of a volcano is called a volcanic plume or eruption cloud. It consists of ash, gases, and steam that are emitted during a volcanic eruption and can travel long distances depending on wind conditions.
The stages of an eruption column typically include: Jetting phase: Initially, the eruption column is driven by rapid expansion of gas and magma within the volcanic vent. Plume phase: As the column rises, it cools and spreads out due to atmospheric pressure, forming a plume that can reach high altitudes. Dispersal phase: The plume can disperse ash, gases, and other volcanic particles over a large area downwind of the volcano.
Molten rock material that flows over the Earth's surface is called lava. Lava is typically generated during a volcanic eruption and can create new landforms such as lava fields, volcanic cones, and lava tubes as it cools and solidifies.
The Krakatoa eruption of 1883 emitted an estimated 6 cubic miles (25 cubic kilometers) of volcanic ash, dust, and sulfuric gases, including carbon dioxide. The exact amount of carbon dioxide specifically emitted is difficult to quantify accurately due to limited historical records and variations in estimating methods.

Sulfur is not produced by volcanic outgassing, as it is a solid mineral that can be released during volcanic eruptions but is not a gas emitted directly from volcanoes.

Primary polluters are air pollutants that come directly from a source. A volcanic eruption is an example of a primary pollutant.
Volcanic eruptions release large amounts of sulfur dioxide and ash into the atmosphere. The sulfur dioxide can react with water vapor to form sulfuric acid aerosols, which can scatter sunlight and cool the Earth's surface. However, the ash particles can also absorb sunlight and contribute to warming. The overall effect of a volcanic eruption on the atmosphere depends on the specific gases and particles emitted, as well as the eruption's intensity and duration.

A volcano eruption can have severe impacts on people, including the destruction of homes, infrastructure, and agriculture. The eruption can also release ash, toxic gases, and lava, causing health hazards and disruption to daily life. Additionally, volcanic eruptions can trigger secondary hazards such as landslides, tsunamis, and mudflows, further endangering people in the affected area.
No, not all volcanic eruptions emit a large amount of gas. The gas emission during an eruption depends on various factors such as the type of volcano, the composition of the magma, and the intensity of the eruption. Some eruptions may release a significant amount of gas, while others may produce less.
A volcanic crater is the part from which the ejecta or magma are emitted. Commonly a conical depression is left due to the withdrawal of the magma chamber that created the eruption. Sometimes infilled with a crater lake. If the eruption was of the highly explosive variety, there may not be very much of a mountain form surrounding the crater. Examples would include L Taupo in New Zealand, and the Yellowstone caldera.
Water vapor constitutes 70 to 95 percent of all eruption gases
