Sedimentary rocks are formed by the accumulation of sediments. There are three basic types of sedimentary rocks.
Clastic sedimentary rocks such as breccia, conglomerate, sandstone, siltstone, and shale are formed from mechanical weathering debris.
Chemical sedimentary rocks, such as rock salt, iron ore, chert, flint, some dolomites, and some limestones, form when dissolved materials precipitate from solution.
Organic sedimentary rocks such as coal, some dolomites, and some limestones, form from the accumulation of plant or animal debris.
Photos and brief descriptions of some common sedimentary rock types are shown on this page.

Explanation
<span>Potential resources are those that may be used at some future point, but are not being used now, like actual resources. Renewable resources are those that are continually replenished while nonrenewable resources are produced over such long periods of time that they are not considered replenishable. The distinctions are important because resources that are actively being used, actual resources, impact people's daily lives. And if these resources are nonrenewable, rather than renewable, they can only be used for a limited period of time.</span>
