Sedimentary rocks are formed by layers of sediments that build up over along period of time. The rocks are being mixed and compressed together for extended periods of time.

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.

What are the layers formed as sediment builds up over a very long time called?
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.
What happens to the sediment that is carried by water?
Sediment carried by water can be deposited along riverbanks, in lakes, or the ocean, forming sediment layers. It can also be transported over long distances and eventually settle at the ocean floor. Sediment can impact aquatic ecosystems, increase turbidity, and contribute to erosion.
What agent of erosion and deposition formed long island?
Long Island was formed by the action of glaciers during the last Ice Age. The movement and melting of the glaciers carved out the land and deposited sediment, shaping the landmass we see today.
Why can you see different layers in sedimentary rocks?
Different layers in sedimentary rocks are formed from the deposition of sediments over time. Each layer represents a period of deposition under specific environmental conditions, such as changes in sediment type, grain size, or fossil content. As new sediments accumulate on top of existing layers, they form distinct strata that can be distinguished based on characteristics like color, texture, or composition.
Why are earth rock layers different?
Earth rock layers differ due to variations in the types of sediment that were deposited over time and the environmental conditions that influenced their formation. Factors such as erosion, climate, and geological activity can result in the formation of distinct rock layers with different compositions and characteristics.

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 a long period of time the layers of sediment turn into?
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.
What happens when sediment builds up after a long time?
When sediment is built, chinese men start to shave thier asses with sumaria sords while epicman808 sings a song about vipond
Are river deltas caused by erosion?
No, deltas are formed from the deposition of the sediment carried by the river as the flow leaves the mouth of the river. Over long periods of time, this deposition builds the characteristic geographic pattern of a river delta.
How are rocks made?
When pressure pushes down on sediment, the sediment turn solid because they have sat aside for a long time and the pressure builds up to form a rock.
What processes turn sediment into sedimentary rock?
The processes of compaction and cementation of this sediment over a long period of time turn the sediment into rock.
Rocks formed from sediments deposits?
Sedimentary rocks are formed from sediment deposits (gravel, sand, silt, clay) over long periods of time either on land or in water (lakes, oceans). As more and more sedimentary layers are deposited, the newer layers exert pressure on the older layers, which compacts the loose particles and cements them together - forming sedimentary rocks. Sedimentary rocks can also be formed through the precipitation of dissolved minerals to form limestone or dolomite.
Crude oil is a fossil fuel what is a fossil fuel and how was the fossil fuel crude oil formed?
A fossil fuel is the remnant of organic materials that died millons of years ago. When an organism died that long ago, say a plant, it became buried under layers and layers of sediment(aka mud, sand, etc.). Over time, the pressure from these layers of sediment compressed the plant to the point that it underwent chemical changes, and became crude oil(Coal is also formed this way, so is natural gas, propane, and other fuels). Our world is powered by dead organisms from millons of years ago.
Which process formed the rocks layers in the canyon wall?
The rock layers in the canyon wall were formed through a process called sedimentation. This involves the accumulation and deposition of sediment materials such as sand, silt, and clay over time. As these sediments compact and harden due to pressure, they form distinct layers seen in the canyon wall.
What happens to the sediment that is carried by water?
Sediment carried by water can be deposited along riverbanks, in lakes, or the ocean, forming sediment layers. It can also be transported over long distances and eventually settle at the ocean floor. Sediment can impact aquatic ecosystems, increase turbidity, and contribute to erosion.
What rock formed out of sediment that have been pressed or cemented over a long period of time?
Sedimentary rock is formed from sediment that has been compacted and cemented together over time. Examples include sandstone, limestone, and shale, which form from the accumulation of sediment such as sand, shells, and mud.
Why do you think paleontologists find fossils of small water plants but few other plants in deepest of rock layers?
No land plants in the deepest rock layers. Water plants are easily covered with sediment while land plants rot long before sediment covers them usually.
