Dec 06, 2018· A sedimentary rock is a classification of rock that forms from layers of sediments deposited and consolidated at the bottom of oceans, lakes, or other bodies of water. These rocks are formed from sediment such as minerals and other organic matter. See the fact file below for more information on the sedimentary rock or alternatively, you can download our 24-page Sedimentary Rocks
Sedimentary rocks are produced by the weathering of old rocks, which breaks apart the rocks into particles or fragments called sediment. The loose grains of sediment are typically deposited and then compacted or cemented together, and this process forms a new type of rock.
The most recent layers of sedimentary rock were formed as the seabed of the ancient Champlain Sea at the end of the last ice age about 14,000 years ago.: The principle of superposition states that a sedimentary rock layer in a tectonically undisturbed sequence is younger than the one beneath it and older than the one above it.: It is a sedimentary rock, but the harder forms, such as anthracite ...
Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. It also contains a cementing material that binds the sand grains together and may contain a matrix of silt- or clay-size particles that occupy the spaces between the sand grains. Sandstone is one of the most common types of sedimentary rock, and ...
Rocks on Earth are often broken down by the process of weathering. These broken particles, called sediments, are carried away by streams and rivers. When these particles collect and become compacted together over time, they stick together and form a larger structure. These larger structures are referred to as sedimentary rocks.
Dec 30, 2018· Sedimentary rocks are formed when weathered (broken down) pieces of sediment (fragments of minerals, rock, and organic material) are carried by moving water into a larger body of water like a lake or the ocean.

Sedimentary rock, rock formed at or near Earths surface by the accumulation and lithification of sediment or by the precipitation from solution at normal surface temperatures. Sedimentary rocks are the most common rocks exposed on Earths surface but are only a minor constituent of the entire crust.
a sedimentary rock formed from the sediments of ancient living things. chemical rock. a sedimentary rock that forms when water dissolves mineral from existing rocks. The mineral crystalize out to form a rock. Coal. ORGANIC ROCK Mostly formed from prehistoric plants and animals finely weathered.
Nov 09, 2015· (1) Clastic sedimentary rock consists of cemented-together clasts, solid fragments and grains broken off of preexisting rocks (the word comes from the Greek klastos, meaning broken); (2) biochemical sedimentary rock consists of shells; (3) organic sedimentary rock consists of carbon-rich relicts of plants or other organisms; and (4) chemical sedimentary rock
Sedimentary Rocks. Sedimentary rock is naturally formed in the Earths crust. It is formed when sediment deposits form layers, compact, and then cement together, creating a new rock. Sedimentary rocks are used for building materials, and sometimes they even contain fossils.
Aug 29, 2019· Sedimentary rocks, mostly consist of weathered remain of igneous rocks along with organic matter from the remains of marine organisms. These rocks comprise only about 5% of the earths crust. In spite of it, sedimentary rocks cover about 75% of the total land surface. Types of Sedimentary Rocks. There are many types of sedimentary rocks.

The classification of clastic sedimentary rocks is based on the particle types found in the rock. Some types of clastic sedimentary rocks are composed of weathered rock material like gravel, sand, silt, and clay. Others can be constructed from the break up and deposition of shells, coral and other marine organisms by wave-action and ocean currents.
sedimentary rocks. Some features, however, are consistently useful for rock identification. For example, rocks that have a gritty feel (like sand paper) are usually sedimentary. Many igneous rocks show randomly oriented large minerals, especially those that have been cooled very slowly. Rocks that look squished are usually metamorphic.
Sedimentary rocks are formed at the surface of the Earth, either in water or on land. They are layered accumulations of sediments-fragments of rocks, minerals, or animal or plant material. Temperatures and pressures are low at the Earths surface, and sedimentary rocks show this fact by their appearance and the minerals they contain.

Get ready for some awesome sedimentary rock facts! Sedimentary rocks are actually formed by sediment. It is piled up over time, usually in layers at the bottom of the ocean or even lakes. The sediment can include all sorts of things like minerals, bits of plants, shells, corals and algae, and all sorts of other weird and wonderful things.
Sedimentary rocks are formed over millions of years when sediments (tiny pieces of rocks and animal skeletons) are pressed together at the bottom of seas and rivers. Examples include sandstone, coal and chalk. Some sedimentary rocks contain fossils (bones or shells of living things that were buried long ago and have turned to stone).
Sedimentary rock is one of three types of rock found on Earth. The others are called igneous and metamorphic. Igneous and metamorphic rocks are the most common rock types in Earths crust. Sedimentary rock is the most common rock type found at its surface.
1. Melted rock or magma is sent to the earth's surface by a volcano. It cools and forms an igneous rock. 2. Next the weather, or a river, and other events will slowly break up this rock into small pieces of sediment. 3. As sediment builds up and hardens over years, a sedimentary rock
