solution

Two or more substances mixed to form a single, homogenous phase. One of the substances is the solvent and the others (solutes) are said to be dissolved in it.

The constituents of a solution may be solid, liquid, or gaseous. The solvent is normally the substance that is present in greatest quantity; however, if one of the constituents is a liquid this is considered to be the solvent even if it is not the major substance.

solution

In earth science, process by which the minerals in a rock are dissolved in water. Solution is one of the processes of erosion as well as weathering (in which the breakdown of rock occurs without transport of the dissolved material). An example of this is when weakly acidic rainfall dissolves calcite.

Solution commonly affects limestone and chalk, which are both formed of calcium carbonate. It can occur in coastal environments along with corrasion and hydraulic action, producing features like the white cliffs of Dover, as well as fluvial (river) environments, like the one that formed Cheddar Gorge.

Solution is also responsible for the weathering of many buildings, monuments and other structures.

solution

In algebra, the value of a variable that satisfies a given equation; see root.
