The basic unit in this system of classification is the formation. Stratigraphy is the study of the sequence of rock layers in an area. These are generally described from the oldest to the youngest. The information on age, environment of deposition or mode of formation comes from the rocks themselves or their relationships to one another. 0y.

Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top.

Ignimbrite, a volcanic rock deposited by pyroclastic flows. Volcanic rock (often shortened to volcanics in scientific contexts) is a rock formed from lava erupted from a volcano.Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some …the soft layer of the mantle on which the tectonic plates move. -soft, liquidy plastic rock. Mesosphere. the strong, lower part of the mantle between the Asthenosphere and the outer core. -strong, solid rock. Tectonic Plate. a block of lithosphere that consists of the crust, and the rigid outermost part of the mantle. Oceanic Crust. Pluton and plutonic bodies. Plutons or plutonic bodies are masses of intrusive igneous rock that have solidified underground, as opposed to volcanic (extrusive) rocks that solidify only after erupting onto the surface.

The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure.

Although the rocks of the lithosphere are still considered elastic, they are not viscous.Sedimentary layers - some terms. Laminations are thin discrete layers of rock. Formations are groups of sedimentary rocks which have formed at the same time and contain similar sedimentary rocks. They are mappable units that formed under distinctive environmental conditions.
