What else can I help you with?
What must occur for an igneous rock to become loose sediment?
erosion
What makes a fossil form?
It gets buried in sediment
What happens when heavy rain builds up in dry sediment?
Mudflows then occur after
What most occur for a fossil to form?
the organism must be buried in sediment soon after it dies.
Picking up sediment and moving it to another area is called?
Picking up sediment and moving it to another area is known as sediment transport.
How does mass waste deposit sediment?
Mass wasting deposits sediment by the downslope movement of weathered rock or soil due to gravity. It can occur as landslides, rockfalls, mudslides, or other forms of mass movement, transporting sediment downslope where it may accumulate, creating sediment deposits.
Where does the final deposition of sediment usually occur?
It commonly occurs in bodies of water such as lakes or oceans.
During lithification what two processes occur?
During lithification, two processes occur: compaction, which involves the reduction of pore spaces between sediment grains due to the weight of overlying sediments, and cementation, which involves the precipitation of minerals in the pore spaces, binding the sediment grains together to form rock.
What is the of process of moving sediment to other places?
The process of moving sediment to other places is called sediment transport. It can occur through erosion, where sediments are lifted and carried by wind, water, or ice to be deposited in new locations. Sediment transport plays a key role in shaping landscapes and ecosystems.
What makes up sediment?
Silt and clay size sediments form shale.
Where does deposition of sediment commonly occur?
It most commonly occurs in bodies of still water such as lake or the sea.
Why do sandbars occur?
Sandbars occur when sediment is deposited by water, usually in shallow areas such as rivers or coastlines. They can form due to changes in water flow, wave action, or changes in sediment supply. Sandbars are dynamic features that can change over time due to natural processes.
