GEOLOGY

Detailed explanation-1: -Sedimentary rocks can form when water evaporates and minerals crystalize. Compaction takes place when existing rocks are changed by extreme temperature, pressure, or fluids. Each rock type can follow only one pathway of the rock cycle.

Detailed explanation-2: -Chemical sedimentary rocks form by chemical precipitation that begins when water traveling through rock dissolves some of the minerals. These minerals are carried away from their source and eventually redeposited, or precipitated, when the water evaporates away.

Detailed explanation-3: -Crystalline rocks are formed because of the polymerization of minerals. The Crystalline rocks are called so because of the excess of crystals that are present in them and also because of the highly organized microscopic structures of these crystals for which the highly tensed geological processes are responsible.

Detailed explanation-4: -3. chemical rocks-forms when minerals that are dissolved in a solution crystallize. Limestone can form when calcite that is dissolved in lakes, seas, or underground water comes out of solution and forms crystals. They can also form from mineral deposits left when seas or lakes evaporate.
