Bedrock
Geology is the study of rocks and minerals. Stratigraphy is the study of rock layers (stratification). Stratigraphers study the way rocks, and their relationships to each other, change over time. Determining the depth and type of bedrock helps geologists and stratigraphers describe the natural history of a region.

How does limestone change throughout the rock cycle?
Lime mud gets buried by overlying sediments over long periods of time and turns into limestone. Limestone in the oceans gets dragged to subduction zones where it gets recycled into the mantle (geosphere), Over time, the limestone is broken down into its chemical parts and may come back to the surface as volcanic "CO"_2 (in the …

The Rock Cycle
There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Plate tectonics | Definition, Theory, Facts, & Evidence
A cross section of Earth's outer layers, from the crust through the lower mantle. In essence, plate-tectonic theory is elegantly simple. Earth 's surface layer, 50 to 100 km (30 to 60 miles) thick, is rigid and is composed of a set of large and small plates. Together, these plates constitute the lithosphere, from the Greek lithos, meaning ...

Mountain Growth Influences Greenhouse Effect – Weathering of Rocks …
The unstated implication of the results of this research is that weathering following orogenies, or mountain building episodes, result in a net release of CO2, and is ultimately responsible for atmospheric CO2 concentrations. Therefore, CO2 levels vary over geologic time; that is exactly what the rock records show.

Plate Tectonics
Plate tectonics shapes global landforms and environments through the rock cycle, mountain building, volcanism, and the distribution of continents and oceans. These phenomena, ultimately driven by Earth's internal heat, have far-reaching effects on other parts of the Earth system, including the sea level experienced along coastlines.

The same thing happens to sediment formed from the weathering and erosion of rock. Over time, sediment accumulates in oceans, lakes, and valleys, eventually building up in layers and weighing down the material underneath. This weight presses the sediment particles together, compacting them.

Module 11 Metamorphic Rocks | Science 111
Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.13: The platy layers in this large outcrop of metamorphic rock show the effects of pressure on rocks during metamorphism.
