اقرأ أكثرBedrock
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.
اقرأ أكثرHow 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 …

There are three main types of rocks: sedimentary, igneous, and metamorphic.

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 ...

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.
اقرأ أكثرPlate 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.

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.
