How can igneous rocks form
Web22 de nov. de 2024 · Any igneous rock that forms on the surface is called extrusive rock or volcanic rock because it was extruded from the inside of the earth volcanically. When large crystals formed deep in a magma chamber are ejected in surface eruptions and blend in with lava or ash to create rock, this blended rock is called porphyritic rock. WebDifferent types of rocks form in Earth’s different environments at or below the Earth’s surface. For example, igneous rocks form when molten rock from the mantle or within the crust (see plate tectonics) cools and either hardens slowly underground (e.g., granite), or hardens quickly if it erupts from a volcano (e.g., basalt).
