Layers of sediment can build up over millions of years to form different types of rock, such as sandstone, shale, and limestone. These layers are created through the accumulation of particles like sand, mud, and shells that settle at the bottom of bodies of water or are deposited by wind. Over time, pressure from more sediment layers above compacts and hardens the sediments into rock.
The process that presses sediments together is compaction. Thick layers of sediment build up gradually over millions of years. These heavy layers press down on the layers beneath them. The weight of new layers further compacts the sediments, squeezing them tightly together. The layers often remain invisible in sedimentary rock.
it gets weathered into sediment, then it gets washed into the ocean, sediment layers up over millions of years, and it gets squashed into sedimentery rock, then metamorphic and so on.
Chalk is formed from layers of compressed marine organisms, primarily calcium carbonate derived from the shells of plankton. These layers build up over millions of years in a process called sedimentation.
It can take thousands to millions of years for sedimentary rock to form, depending on factors such as the type of sediment and the environmental conditions. The process involves the accumulation and compaction of sediment layers over time, leading to the eventual transformation into solid rock through lithification.
The time it takes for sediment to form can vary greatly depending on factors such as the type of sediment, environmental conditions, and the presence of organic material. In general, sediment deposition can occur slowly over thousands to millions of years, with layers building up gradually through processes like erosion, transportation, and deposition.
The process that builds up sediment over millions of years is called sedimentation. It involves the accumulation of weathered rocks, minerals, and organic material that settle in layers on the Earth's surface. Over time, these layers of sediment can become compressed and cemented together to form sedimentary rocks.
Layers of sediment are pressed under the earth for thousands and millions of years, and solidify into rock.
The building up of layers of sediment is known as sedimentation. This process occurs when particles of rocks, minerals, and organic matter settle and accumulate on the Earth's surface over time, forming layers of sediment. Over millions of years, these layers can become compressed and cemented together to form sedimentary rocks.

The layers formed as sediment builds up over a long time are called sedimentary rock layers. These layers are created through the accumulation and compaction of sediments over millions of years, resulting in distinct strata that can provide insights into Earth's geological history.

Over millions of years, layers of sediment may build up and harden into sedimentary rock. Some of the many forms of sedimentary rock include sandstone, rock salt, and coal. Sandstone forms as sand hardens.

The layers are called strata, and they form through the deposition of sediment such as mud, sand, or silt over millions of years. The oldest layers are found at the bottom, with younger layers building up on top, providing a record of Earth's history and changes over time. These layers can contain fossils and minerals that help scientists understand past environments and events.
It is sand. Edit: Over many thousands of years - sediment gets compressed and compacted into layers. The layers form rocks such as slate and coal.
