How Do Extrusive Rocks Form - The lava cools quickly as it contacts air or water. The lava cools quickly as it pours out onto the surface ( figure below). Igneous rocks are called extrusive when they cool and solidify above the surface. Extrusive rocks are formed by the molten lava which comes out of volcanoes, reaches the earth’s surface and cools down. Extrusive igneous rocks form above the surface. Extrusive igneous rocks cool much more rapidly than. The molten rock erupts or flows above the surface as lava , and then cools forming. How are extrusive and intrusive rocks formed class 7? Igneous rocks which form by the crystallization of magma at the surface of the earth are called extrusive rocks. Extrusive igneous rocks cool much more rapidly than.

Extrusive igneous rocks forms when magma erupts above earth's surface as lava. Extrusive igneous rocks form above the surface. Extrusive rocks are igneous rocks that are formed when molten rock (magma) cools and solidifies. Extrusive igneous rocks cool much more rapidly than. Igneous rocks which form by the crystallization of magma at the surface of the earth are called extrusive rocks. They tend to have small crystal sizes because they cool very quickly. Extrusive igneous rocks, or volcanics, form when magma makes its way to earth's surface. The molten rock erupts or flows above the surface as lava , and then cools forming. Intrusive rocks are formed from magma that cools and solidifies within the crust of the planet. Igneous rocks are called extrusive when they cool and solidify above the surface.
