Dynamic metamorphism occurs when changes in rocks take place because of large-scale movements of the Earth’s crust. The rock may get pushed to greater depths under the surface of the Earth resulting in the formation of new rocks. Example: Shale gets converted to hornfels.
Metamorphism caused by extreme temperature is called thermal metamorphism. It occurs because of the heat generated by magma or due to the friction caused by two moving rocks. Example: Forming of slate from clay
Metamorphism is a process by which these metamorphic rocks are formed. Types of Metamorphism, Process of Metamorphism with examples are
There are three types of Metamorphism – Thermal metamorphism, Dynamic metamorphism, Regional metamorphism. Metamorphism caused by extreme temperature is called thermal metamorphism.
The process of the transformation of rocks from one form to the other in a cyclic manner is known as the rock cycle. It includes the following processes:
Important Uses of Rocks – Rocks have played a great part in the development of civilizations. Rocks are used in the construction of many buildings such as granite.
Soil is formed because of weathering and decomposition of rocks. Rocks also contain many minerals. Minerals are inorganic substances that occur naturally.
The igneous rocks are also known as primary rocks as they form the basis of the formation of other types of bricks. Igneous rocks are formed because of the cooling, solidification, and crystallization
Extrusive igneous rocks are formed by cooling molten magma on the surface of the Earth. The molten magma comes onto the Earth’s surface through cracks, fissures, and volcanic eruptions.
Intrusive igneous rocks are formed when magma cools and solidifies below the surface of the Earth. Dolomite and granite are some examples of intrusive igneous rocks.
