Metamorphic rocks are the result of pressure and heat applied to igneous or sedimentary rocks. The appearance of these rocks is transformed along with the structure; for example, metamorphic sedimentary rocks retain the layers, but the layers are bent and compressed. Some examples of metamorphic rock include marble, slate and gneiss.

Types of Rocks Earth Science Lumen Learning

Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals.

What is the difference between a rock and a mineral?

A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. Common minerals include quartz, feldspar, mica, amphibole, olivine, and calcite.A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
