Diagram of how volcanoes occur
Webvolcano diagrams In this topic, we look at how movements in the earth's crust can cause both volcanic eruptions and earthquakes. It also looks at different types of plate boundary and where volcanoes are located. WebThis simple schematic diagram shows the movement of the tectonic plate (light brown) over a mantle plume, or hot spot, to produce a chain of volcanic islands. The superheated magma rises through the mantle …

WebVolcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones, although only the Aleutian Trench and the Java Trench appear on the map in Figure above. Remember your plate tectonics knowledge. 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.
