What is metamorphic rocks
  • 1 answers

Yogita Ingle 7 years, 4 months ago

Igneous and sedimentary rocks deep below the Earth’s surface are buried under the huge weight of the rocks, sediments and soil above them. They are also subjected to high temperatures. The temperature increases by about 25°C for every kilometer below the surface. This heat and pressure can change the composition and appearance of the minerals in rocks. The process of change in the rocks is called metamorphism and the rocks that are formed by these changes are called metamorphic rocks.
Metamorphic rocks are formed when other rocks are changed due to heat or pressure. Examples include slate and marble. Metamorphic rocks are very hard but can be damaged by acids like acid rain (on buildings) or even lemon juice.
