Chemical digestion is the process of reducing food to a size where the nutrients can be absorbed into the bloodstream. This procedure begins in the mouth, continues in the stomach, and ends in the small intestines. Digestive enzymes are the primary coordinators of chemical digestion.

Weathering describes the breaking down or dissolving of rock s and mineral s on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

21/07/2017 · Weathering. Weathering, how rocks break down, can happen in a multitude of ways, including adding water and freezing, impacting plant roots, impact from another object and when minerals expand. Basalt weathers faster than granite because it is not as hard and it's easier for outside substances to impact and manipulate its structure.

Basalt is a type of igneous rock formed by the rapid cooling of lava at the surface of a planet. It is the most common rock in the Earth's crust. Basalt rock characteristics vary from the source of lava, cooling rate, and historical exposure to the elements. High quality fibers are made from basalt deposits with uniform chemical makeup.

Basalt is the most widely distributed basic extrusive rock, with a SiO 2 content ranging from 45% to 52%, and is mainly composed of basic plagioclase and monoclase pyroxene, followed by orthopyroxene, peridot and amphibole. Pyroxene in basalt often has a complete crystalline, short columnar structure; plagioclase in basalt has a fine needlelike nondirectional arrangement.

Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.
