Igneous rock is formed when the Earths molten layers magma cools and forms a hard rock.

. Sedimentary rock takes time to form. The particles that form a sedimentary rock are called sediment and may be composed of geological detritus minerals. As with igneous processes metamorphic rocks form at different zones of pressure depth and temperature as shown on the pressure-temperature P-T diagram.

Settings in geology when the term country rock is used include. Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at Earths surface followed by cementation. The term facies is an objective description of a rock.

Sedimentation is the collective name for processes that cause these particles to settle in place. When country rock is intruded by a dike perpendicular to the bedding plane it is called discordant intrusion while a. Delve into the structure of the Earth to learn what causes earthquakes volcanoes and more.

When describing a pluton or dike the igneous rock can be described as intruding the surrounding country rock the rock into which the pluton has intruded. In metamorphic rocks facies are groups of. Rocks form in nature and they are created three different ways.
