WebThe figure below uses P-T diagrams to show how melting can occur at three different plate tectonic settings. The green line is called the solidus, the melting point temperature of the rock at that pressure. Setting A is a situation (called “normal”) in the middle of a stable plate in which no magma is generated. WebVolcano facts 1. Put simply, a volcano is an opening in the Earth’s surface. Usually found in a mountain, the opening allows gas, hot magma and ash to escape from beneath the Earth’s crust. 2. The word “volcano” comes … WebHow Do Volcanoes Erupt?

The friction produced melts the Earth’s crust, creating magma. Extremely heated magma creates pressure and slowly rises to the surface through the fractures between the tectonic plates. Over time it finds its way out through a volcanic vent.
