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 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.
Process in which sediment is laid down in any location?
First of all there is weathering (erosion) of rocks at some place, they are carried away by wind or water at some other place and deposited there.Layers on layers are deposited to form sediments.
Do other rocks need to experience metamorphism to be changed into sedimentary or igneous rocks?
No. Any rock at the surface can be eroded, deposited as sediment, and then lithified into sedimentary rock. Most rock that melts into magma goes through a metamorphic phases first, however.

When a river slows down what types of sediment will be deposited first why?
The heaviest sediment will always be deposited first. Which sediment is the heaviest in that flowage can vary widely.

When forming a sedimentary rock the layer that is deposited first is the?
soil
In a stream channel what sediment is deposited first?
gravel sized particles
Is this true or false When a river slows down and deposits its sediment load smaller particles of sediment are deposited first?
true
When a river slows down and deposits its sediment load smaller particles of sediment are deposited first. True or False?
True
When a river slows down and deposits its sediment load smaller particles of sediment are deposited first?
No, the heavier are deposited first and then the medium ones and lastly the very smallest (sand). This can be seen clearly when you look at what are called out washed plains.
What must happen to an igneous rock before it can become a sedimentary or metamorphic rock?
To become a sedimentary rock, an igneous rock must first be weathered, and then eroded, and then deposited as a sediment, and then consolidated (e.g. by cementation or pressure welding of grains.) To become a metamorphic rock it must be transformed by heat and pressure, which it can do directly (e.g. granite turning into gneiss) or after first turning into a sedimentary rock.
