Is marble intrusive or extrusive
WitrynaIntrusive (or, plutonic) igenous rocks form from magma that has cooled below the Earth's surface. Because this cooling process is slow, visible (or, phaneritic) mineral grains have time to form and are usually visible with the naked eye. When any mineral grains in a sample exceed 2 cm in size, the rock is called a pegmatite. WitrynaThe melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. Igneous rocks are divided into two groups, intrusive or extrusive, depending upon where the molten rock solidifies.Intrusive Igneous Rocks:Intrusive, or plutonic, igneous rock forms...
