Three Ways Sedimentary Rocks Are Formed | Sciencing
Sedimentary rocks form from the weathering of other rocks, dead organic remains or chemical precipitation. Processes used to form sedimentary rocks include classic sedimentation, chemical sedimentation and biochemical sedimentation. Examples of sedimentary rocks include shale, limestone and coal.

Layers of Sedimentary Rock Deposited by Global Flood
Whether looking into the Grand Canyon from one of the rim overlooks or traversing through the Grand Canyon on foot or by raft, the answer to this question is obviously yes. The fossil-bearing sedimentary layers deposited by the Flood can be seen exposed in the walls, stacked on top of one another like a huge pile of pancakes.

The Grand Canyon, From the Sediment Perspective
The Grand Canyon is known around the world for its incredible layers, and defying depth. It formed from the bed of the Ancient Colorado River, as it wound around the plateaus in the Colorado Plateau Province. The water in the river, and the sediment it carried wore away at the bed for ages, until the canyon was formed.

Rates of sedimentation are measured in three main contexts. The first is the study of sedimentation systems that are active today; the second is what has come to be known as source-to-sink study; the third is the study of the relationship between sediment accumulation rate and measurement timespan.

Sedimentation
Marble, a metamorphosed limestone, is used for tile and sculptures. Limestone, a chemical precipitate sedimentary rock, is used to make Portland cement as the basis for all concrete systems. Limestone is burnt to force out the water in its chemical form, producing lime, combining it with water, sand, and gravel; we're going to get cement.

Sedimentary Rocks
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.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface. Sedimentary rocks often have distinctive layering or bedding. Many of the picturesque views of the desert southwest show mesas and arches made of layered sedimentary rock. Common Sedimentary …

Limestone
Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic ( sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).
