Why are sedimentary rocks formed in layers?
Sedimentation of transported weathered and eroded material is continuous, cyclical, or event based. New sediments are deposited on top of existing sediments, forming layers that may be visible in a sedimentary rock body.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
What are rocks formed from sediments deposited over time?
glotonet rocks are made by sand and minerals being pressed together
How can an igneous rock change into a sedimentary rock over millions of years?
When an igneous rock is eroded by rain, wind, etc. the small grains and dust are swept into streams and rivers. Eventually they are deposited in lakes, seas or oceans. After a long time these sediments build up and are covered by later sediments. Due to compaction from overlying sediments they gradually turn into a rock, a sedimentary rock.
What is the process by which sedimentary rocks are arranged in layers?
Each layer is deposited over time as the environment changes over millions of years. The process is deposition of differing sediments, forming strata. When buried at great pressure, the rock is formed, and the strata are evident. Layers may also be caused by lamination of the sediments or through mineral banding (especially in sandstones).
Why are sedimentary rocks formed in layers?

What is likely to happen to sediments deposited by a river over hundreds or thousands of years?
Thet gradually change into a rock, mostly by compaction.
How would you define sediment and sedimentary rock?
Sediments- Sediments are lose minerals such as rock fragments, mineral grains, and bits of a shell that has been moved by ice, wind, water and gravity.Sedimentary rock- Is a rock formed my sediments deposited into layers and being pressurized over time.
The word that refers toany rock that has been formedfrom layers of grains which have been deposited and then squashed?
Sedimentary rocks are formed from sediments over time. Individual grains are deposited and then squashed together to form larger rocks.
How does Delta form?
As a river flows it picks up sediment and carries it away. When the river reaches the ocean the sediments deposited, over time a delta forms.
Where does oil come from naturally?
If you mean crude oil, then this is produced in the ground over geologic time by the decomposition of small marine creatures that were trapped in the sediments as they were deposited.
Where are the oldest layers of a sandstone rock located?
Sandstone is a sedimentary rock. Sedimentary rocks form from sediments that deposited by the wind and water. Over the time those sediments will get pressed and cemented together. It can take millions of years for sediments to become a rock. So the oldest layers of a sandstone are on a bottom.
How can a cliff can be turned into a layer of mudstone over millions of years?
Through the effects of weathering and the transportation of the resultant sediments by erosion to a place where the sediments are deposited in still waters or in land based sedimentary deposits where they are compacted and cemented together into a rock.
How do cays form?
A Cay is formed when Ocean currents loose sediments as they pass over reefs Gradually layers of deposited sediment build up on the surface of the reefs
What are rocks formed from sediments deposited over time?
glotonet rocks are made by sand and minerals being pressed together
What landform wsa most likely made by the process of depositing sediments?
A delta is a landform that is most likely made by the process of depositing sediments. Deltas are formed at the mouth of a river where the river's sediments are deposited as the river slows down and enters a larger body of water, such as a lake or an ocean. The accumulation of sediments over time creates a triangular-shaped landform with various channels and distributaries.
What are two ways that scientists make observations?
2 ways scientist make observations: recording information in an experiment examining something over time
