Occur when hot, runny magma reaches surface. Gasses can escape more easily so less pressure builds up. By Karanasiou Katerina B1. 07/02/2017. Volcano…. Volcano is open passageway from the interior of the Earth that allows blast rock and gases from the interior to the cortex surface in the form of lava. This activity creates mountains. Lesson Objective:. To be able to explain the cause, impacts and response of a volcanic eruption in an LIC. Characteristics of volcanoes. lava flow.
