How can you identify different types of rocks? Include information that might be useful to identify rocks in fields and in large areas of rocks.

A rock is a non-living earth material that is naturally formed. Rocks consist of mineral grain collections which are held in a solid mass.

Explanation:

Rocks are primarily identified by their minerals and texture. A distinctive mineral set is present in each type of rock. A rock may consist of grain, such as quartzite, of all minerals. More generally, a mix of various minerals consists of rocks. The texture is a description of mineral grain size, form, and arrangement.

Igneous Rocks:-

Cooling magma forms igneous rocks. Lava is magma that erupts on the surface of the earth. The chemical makeup of the magma and its refreshment speed determine how cool and crystallized rocks form, like minerals.

Sedimentary Rocks:-

By combining and cementing sediments, broken rock-like gravel, sand, silt, or clay rocks. Sedimentary rocks form.

The weathering and erosion of existing rocks can lead to the formation of those sediments. Chemical precipitates, which have been left behind by the liquor, are also included in sedimentary rocks.

Metamorphic Rocks:-

Metamorphic rocks occur when heat or pressures within the Earth change minerals in an existing rock.
