Sedimentary Rocks. Rivers, oceans, winds, and rain runoff all have the ability to carry the particles washed off of eroding rocks. Such material, called detritus, consists of fragments of rocks and minerals.When the energy of the transporting current is not strong enough to carry these particles, the particles drop out in the process of sedimentation.

Erosion is a mechanical process, usually driven by water, wind, gravity, or ice, which transports sediment (and soil) from the place of weathering. Liquid water is the main agent of erosion. Gravity and mass wasting processes (see Chapter 10, Mass Wasting) move rocks and sediment to new locations.

Cementation (geology) Cementation involves ions carried in groundwater chemically precipitating to form new crystalline material between sedimentary grains. The new pore-filling minerals forms "bridges" between original sediment grains, thereby binding them together. In this way, sand becomes sandstone, and gravel becomes conglomerate or …

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Grain Size. Detrital rock is classified according to sediment grain size, which is graded from large to small on the Wentworth scale (see figure).Grain size is the average diameter of sediment fragments in sediment or rock. Grain sizes are delineated using a logbase-2 scale [9; 10].For example, the grain sizes in the pebble class are 2.52, 1.26, 0.63, 0.32, 0.16, …

5.2: Weathering and Erosion. Bedrock refers to the solid crystalline rock that makes up the Earth's outer crust. Weathering is a process that turns bedrock into smaller particles, called sediment or soil. Mechanical weathering includes pressure expansion, frost wedging, root wedging, and salt expansion. Chemical weathering includes carbonic ...

Inorganic chemical sedimentary rock is made of minerals precipitated from ions dissolved in solution. Inorganic chemical sedimentary rock forms in environments where ion concentration, dissolved gasses, temperatures, or pressures are changing, which causes minerals to crystallize, such as through the process of evaporation.

Sediment is then transported by erosion. Moving water, wind, and glaciers then carry these pieces from one place to another. The sediments are eventually dropped, or deposited, somewhere. The sediments may then be compacted and cemented together by minerals. This forms a sedimentary rock. This whole process can take hundreds or thousands of …

The rock cycle is the natural, continuous process that forms, breaks down, and reforms rock through geological, chemical, and physical processes. Through the cycle, rocks convert between igneous, metamorphic, and sedimentary forms. It is a dynamic system that recycles Earth's materials in different forms, from molten magma deep below …

Rock salt is the name of a sedimentary rock that consists almost entirely of halite, a mineral composed of sodium chloride, NaCl. It forms where large volumes of sea water or salty lake water evaporate from an arid-climate basin -- where there is a replenishing flow of salt water and a restricted input of other water.

Of these, the mudrocks are most abundant, making up about 65% of all sedimentary rocks. Sandstones make up 20 to 25% of all sedimentary rocks, and carbonate rocks account for about 10 to 15% of all carbonate rocks. The Occurrence of Sedimentary Rocks.

The rock cycle is usually said to begin with a hot molten liquid rock called magma or lava. Magma forms under the Earth's surface in the crust or mantle and erupts on Earth's surface as lava.
