WebVolcanic Landforms. Volcanic landforms are divided into extrusive and intrusive landforms based on weather magma cools within the crust or above the crust. Rocks formed by either plutonic (cooling of magma within the crust) or volcanic (cooling of lava above the surface) are called ‘ Igneous rocks’. Extrusive Volcanic Landforms. WebThis network is often referred to as the volcano's plumbing system. These networks can cover vast areas.

Plutonism is the process by which magma rises through the crust and crystallizes as an intrusive igneous rock beneath the Earth’s surface. Pluton is a generic word for any igneous intrusive rock body. Exactly what causes melting is complicated and variable. Assuming the rock is already under metamorphic temperature-pressure ...
Web4.1.3 Igneous Rock Bodies. Igneous rocks are common in the geologic record, but surprisingly, it is the intrusive rocks that are more common. Extrusive rocks, because of their small crystals and glass, are less durable. Plus, they are, by definition, exposed to the elements of erosion immediately. Intrusive rocks, forming underground with larger, …
