Sedimentary Rock

Sedimentary rocks are formed through the accumulation and lithification of sediment, which is composed of minerals. Depending on the mineral composition of the sediment, the resulting sedimentary rock will have different properties, such as its hardness, color, and texture. For example, rock formations like limestone are primarily made up of the mineral calcite, while sandstone is composed of quartz grains.

It depends on the specific application or use. Sedimentary rocks are formed from the accumulation of sediments and can be more easily broken down and compacted. They often contain fossils and organic matter. Volcanic rocks are formed from volcanic activity and can be more resistant to weathering and erosion. They often have a more uniform composition and can be more durable. Ultimately, the better choice will depend on factors such as strength, density, and aesthetic preference.

The time it takes for a thick layer of sedimentary rock to form can vary significantly depending on various factors, such as the depositional environment, the rate of sedimentation, and the type of sediment being deposited. In general, it can take anywhere from a few hundred to millions of years for a thick layer of sedimentary rock to form.

It is true that the composition of a sedimentary rock depends upon the composition of the rocks and living things its sediments come from. Sedimentary rocks form through lithification.

Through the processes of weathering (breaking of rocks into smaller pieces) and erosion (transport of material from one place to another by ice, wind, water, and gravity), or by the transport or exposure of sedimentary rock by tectonic forces, such as plate movements.

The Wentworth Scale commonly measures grains of boulders, cobble, gravel, pebbles, sand, silt, clay and calloid.

Practically anything can be in conglomerate. Conglomerates that might be forming today could even contain metals like steel, aluminum, gold jewelry or plastics and other synthetic materials; of course these conglomerates will not become solid rock for millions of years.

Without igneous rocks, we would not have beautiful granite countertops.

Sedimentary rocks preserve a record of the environments that existed when they formed.

Chemical: Minerals were dissolved in water to form it.

Organic: Formed from the remains of living things.

Clastic: Formed form bits of other rocks.

No, they are composed of fine-grained sediments, grains of which are generally too small to see with the unaided eye. This makes them easily distinguished from rocks like granite, which are composed of grains of minerals large enough to easily identify.

yes they are you have to look at a normole one can tell you

This crystal is face-centered cubic.

disconformities
angular unconformities
nonconformities

The Rock cycle is a process whereby all types of rock are formed then eroded and "recycled" through different depositional processes. Sedimentary rocks can provide evidence that the rock cycle exists by looking at it under a microscope. Sedimentary rocks are formed by the lithification of grains of different sizes shapes and compositions. By detemining the compositions of the grains within a sedimentary rock through a petrographic microscope or through a scanning electron microscope (SEM) then it can be seen that some grains are composed of minerals that are solely igneous in origin. Likewise, sedimentary rocks can be metamorphosed to form meta-sediments.

It becomes weathered and eroded to a residue called "regolith", consisting of sand and the clay-forming minerals. These are washed by rivers to the sea or lake beds, settle on the bottom and eventually their own weight compresses the deposit, squeezing out the water. Dissolved minerals precipitate out to cement the grains together, and there we have a new sedimentary rock.

No, scoria is not a sedimentary rock. Scoria is an extrusive igneous rock that forms when magma is rapidly cooled and solidified on the Earth's surface. It is typically dark-colored and has a vesicular texture due to the presence of gas bubbles that were trapped during the rapid cooling process.

Limestone is rock that formed at the bottom of the sea from the shells, bones, and bodies of fish, crabs, shellfish and other marine life. Because it's from life, it's called organic. Chalk and marble are similar.

No it is a primary igneous structure

The layers of any sedimentary rock are called strata.

The vast majority of fossils are found in sedimentary rock.

It can, but is usually more of a gray colour.

About 2-1/2 to 70 tons!

Yes, clastic rocks are a type of sedimentary rock. They are formed from the accumulation of fragments of pre-existing rocks, minerals, and organic materials. The fragments, known as clasts, are compacted and cemented together to form a cohesive rock.

Shale (a metamorphic rock) goes through heat and pressure than it turns into slate (a sedimentary rock)
