Different kinds of rocks

Answer 1

1. Igneous Rock - produced by solidification of molten magma from the mantle or from molten crust. Magma that solidifies at the Earth's surface conceives extrusive or volcanic igneous rocks. When magma cools and solidifies beneath the surface of the Earth intrusive or plutonic igneous rocks are formed.

• Examples: granite, basalt, gabbro, obsidian, pumice.

2. Sedimentary Rock - formed by burial, compression, and chemical cementation of deposited weathered rock debris or sediments from the Earth's surface. They can also be formed by the precipitation of minerals from saturated solutions, such as is rock salt.

• Examples: shale, sandstone, gypsum, limestone, chert, coal.

3. Metamorphic Rock - created when existing rock is chemically or physically modified by intense heat or pressure.

• Examples: quartzite, slate, marble, granulite, schist.
