Metamorphic rocks typically exhibit foliation, which is the alignment of mineral grains in parallel layers, and a textured appearance due to recrystallization of minerals under heat and pressure. They may also show signs of distortion, such as folding or banding, and often contain new minerals that formed from the original rock due to changes in temperature and pressure. Additionally, the hardness and density of metamorphic rocks tend to increase compared to their parent rocks.
That they have undergone some form of change. For more information on metamorphic rocks please see the related question.
One key characteristic indicating that a rock has undergone metamorphic change is the presence of foliation, which is the alignment of mineral grains in parallel layers due to pressure. Additionally, the rock may exhibit new mineral formations that are stable under high temperature and pressure conditions. Other signs include a denser texture and the presence of schistosity or granoblastic textures. These features differentiate metamorphic rocks from their sedimentary or igneous counterparts.
A rock that has undergone change is called a metamorphic rock. This type of rock forms under high pressure and temperature conditions, causing the original rock to change its mineral composition and texture. Examples of common metamorphic rocks include marble (from limestone) and schist (from shale).
Yes they are. Structural geologists commonly use them to estimate the strain that the rock has undergone by measuring their change in shape.
Metamorphic rock is formed from rock that has undergone a change due to heat and pressure. This process causes the original rock to recrystallize into a new form with different physical and chemical properties. Examples include marble and slate.

Metamorphic rock has undergone changes in temperature, pressure, or chemical composition, causing it to recrystallize and form new minerals.

Metamorphic grade refers to the degree of metamorphic change a rock has undergone compared to its parent rock. It encompasses changes in mineralogy, texture, and structure that occur during the metamorphic process.

Metamorphic rock is igneous, sedimentary, or other metamorphic rock that has undergone a change due to heat and/or pressure. The change could be an alteration in mineralogy, a physical restructuring of existing minerals, or a recrystallization of existing minerals--giving the metamorphic rock a new set of characteristics which indicate that change.
The lithosphere is primarily made up of two types of rocks: igneous and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma, while metamorphic rocks are rocks that have undergone a change in texture and composition due to heat and pressure.
Metamorphic rocks have been changed by heat or pressure. This can be a change in size, shape, or arrangement of minerals.
