Why are extrusive rocks sometimes referred to as volcanic?

An extrusive rock is a rock that has been deposited at the earths surface as a liquid/fluid, coming to the surface form a depth through a fissure in the earth as a liquid/fluid. The most common type of liquid rock is a magma and magmas erupting at the surface are called "volcanoes" and thus the rocks are called "volcanic" rocks.

BIOCHEMICAL SEDIMENTARY ROCKS

Biochemical sedimentary rocks form from sediment derived by biological processes. This typically occurs in the ocean where a variety of atoms float among the water molecules. Ions, such as calcium, magnesium, and potassium, along with trace elements like silicon, fluorine, iron and phosphorous, are ...

Carbon sequestration - Wikipedia

Carbon sequestration is the process involved in carbon capture and the long-term storage of atmospheric carbon dioxide or other forms of carbon to mitigate or defer global warming. It has been proposed as a way to slow the atmospheric and marine accumulation of greenhouse gases, which are released by burning fossil fuels .

Limestone - Wikipedia

Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs.Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3).. About 10% of sedimentary rocks are limestones. The solubility of limestone in water and weak acid solutions leads to karst landscapes, in which ...

Sedimentary Rock Examples - YourDictionary

Sedimentary rocks make up most of the rocks on the earth and are formed when bits of rock, soil or organic matter settles and accumulates. Plant and animal fossils can be found in sedimentary rock. When there is an abundance of plants and animals, fossil fuels develop, like oil, natural gas and coal.
