Describe sedimentary rocks
Describe Sedimentary Rocks. Sedimentary rocks cover the majority of the earth s rocky surface but only make up a small percentage of the earth s crust compared to metamorphic and igneous types of rocks. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. Tuffaceous sandstones contain volcanic ash. As per wikipedia sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of that material at the earth s surface and within bodies of water.

Decades of collective experience allows us to place sedimentary rocks into four broad categories. Sedimentary rocks are the second great rock class. They usually consist of layers or strata. Photos and brief descriptions of some common sedimentary rock types are shown on this page. Whereas igneous rocks are born hot sedimentary rocks are born cool at the earth s surface mostly under water. Examples of sedimentary rocks include limestone sandstone mudstone greywacke chalk coal claystone and flint.
Some varieties of sedimentary rock however are precipitated directly into their solid sedimentary form and exhibit no intervening existence as sediment.

Sedimentary rocks are rocks made of lithified sediment. Decades of collective experience allows us to place sedimentary rocks into four broad categories. The fragments range in size from house sized blocks to micron sized clays conglomerate and breccia gravel in an unconsolidated state sandstone siltstone sand and silt and mudrocks mixtures of silt and clay sized fragments or crystals.

When buried the sediments lose water and become cemented to form rock. These rocks often start as sediments carried in rivers and deposited in lakes and oceans. Siliciclastic or terrigenous deposits contain fragments derived by erosion or weathering of older rocks. When buried the sediments lose water and become cemented to form rock. Sediments are grains of rocks minerals or mineraloids deposited on the surface of the earth.

They typically are produced by cementing compacting and otherwise solidifying preexisting unconsolidated sediments. Tuffaceous sandstones contain volcanic ash. Sedimentary rocks are the lithified equivalents of sediments. Chert some dolomites flint iron ore limestones and rock salt. The fragments range in size from house sized blocks to micron sized clays conglomerate and breccia gravel in an unconsolidated state sandstone siltstone sand and silt and mudrocks mixtures of silt and clay sized fragments or crystals.

Siliciclastic or terrigenous deposits contain fragments derived by erosion or weathering of older rocks. Organic sedimentary rocks form from the accumulation of plant or animal debris. They usually consist of layers or strata. Sedimentary rocks are rocks made of lithified sediment. Sedimentary rocks are formed on or near the earth s surface in contrast to metamorphic and igneous rocks which are formed deep within the earth.

Common sedimentary rocks include sandstone limestone and shale. Chemical sedimentary rocks form when dissolved materials preciptate from solution. Reflect on the rock cycle for an indication of the relationships between the rocks that erode to become sediments and sedimentary rocks.

Sedimentary rocks are types of rock that are formed by the accumulation or deposition of mineral or organic particles at the earth s surface followed by cementation. Clastic sedimentary rocks are made up of pieces clasts of pre existing rocks.
