The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle. Structures of Igneous Rock.
The repetitive inhalation–exhalation cycle is described esoterically in the myth as an up–down motion of Sisyphus and his boulder on a hill. In experiments that test how workers respond when the meaning of their task is diminished, the test condition is referred to as the Sisyphusian condition.
Original - The rock cycle is a fundamental concept in geology that describes the dynamic transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Due to the driving forces of the rock cycle, plate tectonics and the water cycle , rocks do not remain in equilibrium and are forced to change as they ...
A Times story in 1937 chronicled Frank Critzer's efforts to build a home under Giant Rock in the Mojave Desert. The article made a point of saying that an Oldsmobile helped make the trip from L.A ...
Comparing the record about the discordance in the record to the full rock column shows the non-occurrence of the missing species and that portion of the local rock record, from the early part of the middle Eocene is missing there. This is one form of discordancy and the means geologists use to compensate for local variations in the rock record.

The carbon then becomes part of a sedimentary rock when lithification happens. Human technology or natural processes such as weathering, or underground life or water can return the carbon from sedimentary rocks to the atmosphere. From that point it can be transformed in the rock cycle into metamorphic rocks, or melted into igneous rocks.
