3 Types of Rocks and the Rock Cycle Igneous, Sedimentary, Metamorphic
Web extrusive igneous rocks. [figure3] extrusive igneous rocks cool much more rapidly than intrusive rocks. Look through the slideshow to find out more about the three rock types. Web igneous rocks are called intrusive when they cool and solidify beneath the surface. Web extrusive rock forms when magma rises from the mantle, erupts on the earth's surface as lava, and cools and crystallizes quickly on the surface of the. Intrusive rocks form plutons and so are also called plutonic. Web extrusive igneous rocks magma comes to the surface of the earth through volcanoes where it can flow as lava and then cool and crystallises to form extrusive or volcanic. Some cool so quickly that they form an amorphous glass. Web extrusive igneous rocks are erupted onto the surface or into the atmosphere. Web the three types of rock are:
Web extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. These rocks usually form from a volcano (called volcanic rocks.) cool much more. Igneous rocks that form after lava cools above the surface. Web extrusive (or, volcanic) igneous rocks are formed on the earth’s surface as the result of volcanic activity. Web extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Web when lava is extruded onto the surface, or intruded into shallow fissures near the surface and cools, the resulting igneous rock is called extrusive or volcanic. The molten rock erupts or flows above. Web extrusive rock forms when magma rises from the mantle, erupts on the earth's surface as lava, and cools and crystallizes quickly on the surface of the. Look through the slideshow to find out more about the three rock types. Web extrusive igneous rocks are erupted onto the surface or into the atmosphere. They tend to have small crystal sizes because they cool very quickly.
