WebSep 14, 2024 · Rocks formed by the cooling of magma within the crust are called Plutonic rocks. Rocks formed by the cooling of lava above the surface are called Igneous rocks. In general, the term ‘Igneous rocks’ is used to refer to all rocks of volcanic origin. Extrusive landforms are formed from material thrown out to the surface during volcanic activity. WebCharacteristics A body of intrusive igneous rock which crystallizes from magma cooling underneath the surface of the Earth is called a pluton.If the pluton is large, it may be called a batholith or a stock depending on the area exposed at the surface. If the body has an exposed surface area greater than 100 km2, then it’s a batholith, otherwise it’s a stock. rachel riley husband pasha

Because the solid country rock into which magma intrudes is an excellent insulator, cooling of the magma is extremely slow, and intrusive igneous rock is coarse-grained (phaneritic). However, the rate of cooling is greatest for intrusions at relatively shallow depth, and the rock in such intrusions is often much less coarse-grained than intrusive rock formed at greater depth.
