Answer Details
The rocks which are formed by the cooling and solidification of molten magma are called igneous rocks. Magma is a hot, molten rock that is found beneath the Earth's surface. When magma cools and solidifies, it forms igneous rocks.
Igneous rocks can form either on the Earth's surface or beneath it. If magma cools quickly on the surface, it forms small crystals and is called extrusive igneous rock. If magma cools slowly beneath the surface, it forms large crystals and is called intrusive igneous rock.
Examples of igneous rocks include granite, basalt, and pumice. These rocks can be identified by their texture and composition. Igneous rocks have a variety of uses, such as in construction, as building materials, and in jewelry making.
