Which of the following conditions are necessary to cause loose sediment to become sedimentary rock?
The necessary conditions for loose sediment to become sedimentary rock are compaction, which involves the squeezing together of sediment grains, and cementation, which involves the binding of grains together by minerals like calcite or quartz. Over time, these processes form solid rock.
What forces cause rocks to change from one type to another?
Magma subjected to cooling becomes igneous rock. Igneous rock then is subjected to weathering and erosion forming sediment which becomes compacted and cemented as sedimentary rock. Both sedimentary rock as well as Igneous rock when subjected ti heat and pressure become Metamorphic rock. This cycle goes on and on and is called the rock cycle.
Sediment forms layers pressure from water and top layers over thousands of years cause lower layers to stick together and to form what?
Lower layers of sediment can be compressed under the weight of overlying layers, causing the particles to become tightly packed together. Over thousands of years, this pressure can lead to the formation of sedimentary rocks, such as sandstone, shale, and limestone, through processes like compaction and cementation.
How is erosion caused by rivers?
Rivers cause erosion through the processes of hydraulic action (force of water detaching sediment particles from riverbanks), abrasion (sediment particles in the water rubbing against riverbanks), and attrition (sediment particles colliding and breaking down). These processes can wear away the riverbed and banks, leading to the transport of sediment downstream.
By what process does sediment become sedimentary rock?
As rock particles and organic matter are eroded to a place of deposition and are covered by additional particles, eventually the weight from above will start the process of lithification. Lithification is the compaction and cementation of particles which form rock. Compaction squeezes out the fluids and space that exist between the particles, and cementation results when the fluids that are squeezed out are replaced with minerals that were in the fluids. Once cementation occurs, the new sedimentary rock has been formed. Rocks formed in this manner include sandstone, shale, mudstone, breccia, and conglomerate and are called clastic sedimentary rocks.Heat and Pressure

How are sedimentary rocks layers deposited?
Scientists know that gravity cause sediment to be deposite.
What does pressure alone do to sediment?
When pressure is applied to pieces of sediment, compaction takes place. Compaction is the process in which pieces of sediment are under severe pressure and it becomes solid rock. Therefore, pressure turns pieces of sediment into sedimentary rock.
During the rock cycle rocks get broken apart by weathering carried along by erosion and eventually deposited in a body of water What happens next?
It depends on where the sediment is deposited. Not all sediment is deposited in a body of water. If the transport mechanism is a stream then the sediment can be deposited on the flood plain of the river or in a lake. If the sediment is deposited on the flood plain it will do two things. 1) The sediment of the flood plain will eventually lithify and 2) The river will continue to down cut and after X number of years the flood plain will no longer be subject to the flood waters of the river. At this point it is classified as a terrace (a flood plain of the past that is no longer inundated by flood water). The cycle basically starts over at this point with weathering and erosion processes breaking down and transporting the terrace sediment back into the river. If the sediment is transported to a lake, a delta will form. As the sediment is deposited in the lake the main channel of the river will extend out into the lake, this lowers the gradient of the main channel which slows the flow of water through the channel and allows for the deposition of sediment in the channel. When the main channel fills with sediment and no longer has the ability to channel all of the water from the river, dis-tributary channels will form these dis- tributary channels migrate across the delta transporting sediment as they go. Lithification takes place in the lower layers of the delta but this lithified sediment is only subjected to erosion during very high flows that are capable of transporting the sediment that covers the lithified layers.Basically, no matter where the sediment is deposited, it is subject to the processes which weathered and transported it to its current location.Wow really? these guys are just looking for a basic answer not an essay
What are the losses of edges on sediment grains?
Losses of edges on sediment grains refer to the gradual rounding and smoothing of the edges of particles due to processes like abrasion and weathering. This can occur during transport by water, wind, or ice, where impacts and collisions with other particles cause the sharp edges to wear down. As edges are lost, the sediment grains become more spherical and uniform in shape, which can affect their settling behavior, porosity, and overall sedimentary structure in geological formations. Such changes can influence sediment transport dynamics and the physical properties of sedimentary rocks.

What forces cause igneous rock to change to Sedimentary rock?
Igneous rock can change into sedimentary rock through the processes of weathering and erosion. Weathering breaks down the igneous rock into smaller sediment particles, which are then transported by natural forces like wind or water. These sediments accumulate in layers and are eventually compacted and cemented together to form sedimentary rock.
What kind of process can change sedimentary rock into metamorphic rock?
Sedimentary rock can be changed to metamorphic rock by either heat or pressure, or a combination of both. These processes can occur for various reasons including, faulting and folding, divergent and convergent tectonic plates, exposure to magma or lava, burial of sedimentary deposits, etc... Basically the same forces that create earthquakes and volcanoes are responsible for creating metamorphic rock.
What are some forces that causes erosion and carry sediment from one place to another?
Wind, water, and ice are common forces that cause erosion and transport sediment from one place to another. These forces can wear away rock and soil through processes like abrasion, and can carry the sediment in the form of sediment loads or suspended particles to new locations.
