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 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.
Layers formed as sediment builds up over a very long time?
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.
What are the layers formed as sediment builds up over a very long time called?
Strata
What are two ways that a rock layer can cause a gap in geologic record?
When rock layers are eroded or when a sediment is not deposited for a long period of time.
What rock formed out of sediment that have been pressed or cemented over a long period of time?
sedimentary rock
The study of the layers of earth that have been deposited over a long period of time?
The study of the layers of the Earth that have been deposited over a long period of time is called stratigraphy. This field helps scientists understand the chronological order of rock layers and their composition, providing insight into the Earth's past environments and geologic history. Stratigraphy is crucial for interpreting the history of life on Earth and understanding past climate changes.
Why is there layers in the ground?
Because layers form during the period of bog dirt and its been forming from long long ago so layers keep going up ..
How does a newly formed rock turn in to sediment?
Over a long period of time, the rock erodes into sediments. These sediments, along with pressure and water, form sedimentary rocks.
Why are earth rock layers different?
Rock layers are different and unique to each other due to the fact that each layer represents a time period. They are formed when rock, sediment, and minerals settle into one place for a long time and harden when another layer goes over it. Reading rock layers allow geologists to determine how much time has passed. They even sometimes tell of the history of the earth and all of the disasters that have occurred in each era.
Why do you think paleontologists find fossils of small water plants but few other plants in the deepest 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.
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.
Why are plants and animals fossils commonly found in the layers of sedimentary rocks?
dead organisms get buried in dirt,sand,etc which harden and turn into rocks over a long period of time.
