Clastic Sedimentary Rocks - Rock Around The World

The name of a sedimentary rock depends on the size (and sometimes the shape) of the rock pieces that it is made of: Conglomerate is composed of rounded gravel, pebbles, cobbles, or boulders along with smaller rock pieces. Breccia is similar to a conglomerate except its gravel, pebbles, cobbles, or boulders have a sharper, angular shape.

Chemical Sedimentary Rocks - Rock Around The World

Chemical sedimentary rocks form by precipitation of minerals from water. Precipitation is when dissolved materials come out of water. For example: Take a glass of water and pour some salt (halite) into it. The salt will dissolve into the water. If you set the water in a hot and dry place (like Arizona) the water, but not the salt, will

Characteristics of Sedimentary Rocks | Rocks | Geography

(1) Sedimentary rocks are formed of sediments derived from the older rocks, plant and animal remains and thus these rocks contain fossils of plants and animals. The age of the formation of a given sedimen­tary rock may be determined on the basis of the analysis of the fossils to be found in that rock.
