Volcanoes And Earthquakes Questions Medium
A volcanic eruption refers to the release of magma, gases, and other materials from a volcano onto the Earth's surface. It occurs when the pressure within the volcano becomes too high, causing the magma to rise and eventually erupt. This eruption can result in various volcanic activities such as lava flows, ash clouds, pyroclastic flows, and volcanic gases being released into the atmosphere.
On the other hand, a volcanic eruption column specifically refers to the vertical column of ash, gases, and volcanic materials that are ejected into the atmosphere during a volcanic eruption. This column is formed when the erupting magma interacts with water, causing explosive fragmentation and the formation of fine ash particles. The eruption column can rise several kilometers into the sky, driven by the force of the expanding gases and the convective currents within the volcanic plume.
In summary, while a volcanic eruption encompasses all the activities associated with the release of magma and volcanic materials, a volcanic eruption column specifically refers to the vertical column of ash and gases that rises into the atmosphere during the eruption.
