What is eroded soil that is deposited in other places?
It is called sediment.
What is the difference between angular unconformity disconformity and nonconformity?
Angular unconformity is when rocks are deformed and then eroded and then new sediment is deposited on top. Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes. These create gaps in the rock record.
What happens to a metamorphic rock when its weathered?
Weathering of existing rock is the first step in the formation of most sedimentary rock, providing the sediment which will eventually be eroded, deposited, compacted and cemented together.
Can intrusive igneous rock becomes a sedimentary rock?
Yes and No An igneous rock can not just "become" a sedimentary rock, it first has to be weathered and eroded at the surface of the Earth. The debris produced is then washed away as sediment and deposited elsewhere. This deposited sediment then gradually hardens into a new rock which is a sedimentary rock. Thus until igneous rocks are exposed in outcrop, they remain as igneous rocks.
What can pressure in cement layers of eroded sediment into rock?
DINGOES
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.
Are there any rivers that deposit and eroded sediments?
Most rivers have eroded and Deposited sediment.
Clay and silt that have been eroded and deposited are called?
Sediment
What is eroded soil that is deposited in other places?
It is called sediment.
Why cant igneous rock turn into sedimentay rock?
Actually it can - but only if it is first eroded and deposited as sediment.

Disconformity is when igneous or metamorphic rocks are eroded and then sediment is deposited on top. Nonconformity is when either there is no deposition for some time and then deposition resumes or horizontal layers are eroded (but not deformed in any way) and then deposition resumes.

Where to meandering streams occur?
On the outer bank (at the tip of the meander)
What happens to a metamorphic rock when its weathered?
Weathering of existing rock is the first step in the formation of most sedimentary rock, providing the sediment which will eventually be eroded, deposited, compacted and cemented together.
Is a sedimentary rock mean rock made from fire?
No! The term igneous refers to fire. Sediment refers tomaterial deposited from rocks that have been weathered and eroded.
How are shale beaches formed?
Shale beaches are formed from the deposition of sediment form nearby shale cliffs which are eroded. The shale can also be deposited at a beach due to longshore drift.
What can eroded soil enter causing them to fill up with sediment?
Eroded soil can enter drains and waterways, causing them to build up with sediment.
When does a sediment deposit the sediment it is carrying?
When a glacier melts it deposits the sediment it eroded from the land, creating various landforms.
