Where would you find Sedimentary rocks?
As rivers flow to the sea, they may carry mud, sand, pebbles, and boulders along the way. The river drops this material, called sediment, into the sea. As layers of sediment b…uild up over a period of many years, the great pressure of all these layers changes the sediment into sedimentary rock. Therefor you might be able to find sedimentary rock at the bottom of the ocean or a lake or river. (MORE)

What are clastic sedimentary rocks formed from?
Clastic sedimentary rocks are formed from particles of pre-existing sedimentary, metamorphic, or igneous rock that are deposited, compacted, and cemented together by natural p…rocesses. Clastic sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz. (MORE)

What are igneous rocks and sedimentary rocks?
Igneous rocks are made from magma. Magma is made of melted rocks. (When it is underground it is called magma, when it erupts on the surface of the earth, it is called lava…. It's the same material though.) When magma/lava cools, it forms igneous rocks. There are many types of igneous rocks and the specific type of igneous rock can vary according to which minerals are present in the melted rock, how fast it cools, and the presence of things like water. Sedimentary rocks are made out of tiny pieces of debris. This can include tiny rocks, sand, clay, silt, and organic material. (Organic materials can vary from rotted leaves to tiny, shelled ocean creatures, or many other types of organic material.) These bits of material collect in an area, then through compaction and cementation, they stick together to form sedimentary rocks. Sedimentary rocks can also be formed when minerals are dissolved in water and are then resolidified. This type of sedimentary rock is called a chemical sedimentary rock. Oolitic limestone is a good example of this type of sedimentary rock. (MORE)

As the question says, it is, or rather they are, rock! Like all rocks, sedimentary rocks consist of minerals.

Why is sedimentary rock found in basins?
Sedimentary rock is composed of sediments, or little particles of rock, usually weathered away from other rocks by water, and water will carry the particles to lower elevation…s, like basins. (MORE)

How does an igneous rock become sedimentary?
Weathering and erosion cause the igneous rock to break apart causing sediments from it to go somewhere like a river. Than over time compaction and cementation cause it to beco…me a sedimentary rock. (MORE)

Which rock is a sedimentary rock?
A sedimentary rock is a rock formed at or near the Earth's surface by the accumulation and lithification of fragments of preexisting rocks or by precipitation from solution at… normal surface temperatures. Sedimentary rocks can be formed only where sediments are deposited long enough to become compacted and cemented into hard beds or strata. They are the most common rocks exposed on the Earth's surface but are only a minor constituent of the entire crust. Their defining characteristic is that they are formed in layers. Each layer has features that reflect the conditions during deposition, the nature of the source material (and, often, the organisms present), and the means of transport. (MORE)

What is the answer to 20c plus 5 equals 5c plus 65?
20c + 5 = 5c + 65 Divide through by 5: 4c + 1 = c + 13 Subtract c from both sides: 3c + 1 = 13 Subtract 1 from both sides: 3c = 12 Divide both sides by 3: c = 4
