Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. Foliated metamorphic rocks are arranged in sheets or planes, meaning that the composition of the rocks is relatively uniform and disperses fairly evenly due to pressure. They become metamorphic rocks, which form while deeply buried within the Earth’s crust. Metamorphic rocks are very hard but can be damaged by acids like acid rain (on buildings) or even lemon juice (on worktops!). Metamorphic rocks are made by high temperatures and high pressure. 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. Although different rocks can contain the same minerals, they are sorted into different types of rocks depending on how they were formed. Environmental conditions can include changes in temperature, pressure, and mechanical stress, and the addition and subtraction of … The protolith may be sedimentary rock, … Metamorphic rock is the result of the transformation of a pre-existing rock type, the protolith, in a process called metamorphism, which means "change in form" (from the Greek words meta, "change", and morphe, "form").The protolith is subjected to extreme heat (>150 degrees Celsius) and pressure causing profound physical and/or chemical change.

Metamorphic rock can also result when hot, molten rock called magma is forced up through existing rocks in the crust, heating the rocks and increasing the pressure. One example is slate. Sedimentary rock which has been near such forces often looks as if a giant had twisted it and heated it over a fire. During contact metamorphism, broken down pieces of rock near the Earth's surface is altered by magma.
