Metamorphic rocks are formed when other rocks are affected by great temperatures and pressures. They do not melt, but the chemicals they contain may change their forms, or crystal shapes. Marble and slate are two examples of metamorphic rocks.
A metamorphic rock is a type of rock which has been changed by extreme heat and pressure. Its name is from 'morph' (meaning form), and 'meta' (meaning change). The original rock gets heated (temperatures greater than 150 to 200 °C) and pressured (1500 bars). This causes profound physical and/or chemical change.
Metamorphic rocks are formed through the process of metamorphism, which involves the transformation of existing rocks due to high pressure, temperature, or chemical changes. Examples of metamorphic rocks include marble, slate, and gneiss.
Enjoy our metamorphic rock facts for kids. Find interesting information and a range of examples that help explain what metamorphic rocks are and what makes them different from other kinds of rocks. Metamorphic rocks have been changed over time by extreme pressure and heat.
Metamorphic rocks form when existing rocks are exposed to heat and pressure deep within the Earth’s surface. That’s a pretty neat way of understanding different types of rocks! Examples of metamorphic rocks are marble and slate. There are many more with some really weird names like anthracite, quartzite, granulite, gneiss and schist.
Metamorphic rocks are often made from other types of rock. For example, shale, a sedimentary rock, can be changed, or metamorphosed, into a metamorphic rock such as slate or gneiss. Other examples of metamorphic rocks include marble, anthracite, soapstone, and schist.
Rock that has changed in composition or structure in response to changing environmental conditions is called metamorphic rock. The name metamorphic comes from Greek words meaning “change of form.” Such a transformation usually results from great temperatures, pressures, or mechanical stress.

Let’s discover five magnificent metamorphic rocks facts for kids. Metamorphic rocks are rocks that have been changed by heat, pressure, or chemical processes. These changes happen deep inside the Earth, often far below the surface.
Metamorphic rocks are derived from igneous and sedimentary rocks. As soon as rock experiences a change in its physical and chemical conditions, it undergoes metamorphism. During chemical reactions, minerals inside the rock are changed so much that the entire texture of the rock alters with it.
