The action of water and gravity cause them to form in layers.
They accumulate and gather up into thick layers, which with time get compacted and lithified to form sedimentary rock.
Aquifer are underground areas of saturated permeable rock or sediments above layers of impermeable rock that have the ability to hold/retain ground water, preventing it from percolation and infiltration, thereby serving as a form of natural water storage .
When sediments are buried deep under layers, the pressure compresses them in a process called lithification. This process involves the compaction of sediments, where the weight of overlying materials squeezes the particles together, and the cementation, where minerals precipitate from groundwater and bind the particles. Together, these processes transform loose sediments into solid sedimentary rock.
An aquifer transmits ground water freely.
Piles of eroded sediments. Which may or may not become sedimentary rock over time.
A sedimentary rock
Igneous rock
Sediments settle in layers at the bottom of bodies of water, such as lakes, rivers, and oceans. Over time, as more sediments accumulate, they become compacted and cemented together to form sedimentary rock.
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.
basalt
These are sediment particles, such as sand, silt, and clay, that settle down due to gravity. Over time, these sediments accumulate to form layers called sedimentary deposits.
The process of pressing sediments together to form solid rock is called compaction. It occurs when layers of sediment accumulate on top of each other, with the weight of the overlying layers causing the sediments to be pressed tightly together.
When sediments deposit in lakes or oceans, they typically settle in layers on the bottom of the body of water. Over time, these layers can build up and form sedimentary rock.
In disturbed sediments without layers, the relative age of the sediments would be unknown.
Layers of sediments compressed the layers of vegetation to form the coal deposits.
Evaporation and precipitation of sediments can form sedimentary rocks over time through the process of lithification. This involves the compaction and cementation of sediments, creating layers of sedimentary rock.
When rock layers form parallel to each other, it is called stratification. This process occurs when sediments settle and accumulate in horizontal layers over time, resulting in distinct bands or layers of rock.
