Because it requires more energy to transport heavier sediment than lighter sediment. As a river flows it loses energy, and hence begins to drop the heavier sediment. Imagine you had a handful of sand and a handfull of flower. The sand is heavier than the flower, and also larger. If you blow on both of your hands, the flower will be easily blown away, but the sand will be more difficult, because the grains are bigger and heavier, and require more energy to move.
The heavier sediments are the first to overcome the power of the moving water with the power of gravity.

Sediments are laid down in what order?
Under normal conditions, the largest, or the sediments with the most mass, are the first to be laid down, as they are able to more easily resist the force causing the movement of the sediments. Successively smaller particles are laid down after that, as deposition continues.
Is 20 percent NEFE acid heavier than 2 percent KCL water?
first you have to understand the question! and the answer is yes the acid is heavier than the water
When did the first glaciers form?
The earliest evidence of glaciation is found in 2.8-billion-year-old sediments in South Africa.
In rock layers what is usually found at the bottom?
Normally, the oldest rocks are found at the bottom of the layers, being the first of the sediments that were deposited.
What explains why turbigenic sediments are found in graded beds?
During deposition, larger particles usually settle to the bottom faster than smaller particles do.When turbidity currents reach the deep ocean floor, the slope decreases. The current decreases and the largest, most dense sediments are deposited first. This process is called vertical sorting, which results in graded bedding.
Why is a river deposits heavier sediments first and lighter sidements later as it flows along?
After that it would be deposited when the flow of the river is too slow to carry it.
Why do rivers deposit heavier sediments first and then lighter sediment?
More dense material is less buoyant in water than less dense material of equal volume. Sediment shape also plays a role in deposition sequence as material with angular irregular surfaces are more likely to be carried by water flow than smooth surfaces, due to friction with the water. Finally, the size of the sediment particle, particularly of rock material, may be most critical in the sequence of deposition; larger particles are the first to overcome the power of friction encountered in moving water, via gravity.
Why does a river deposit the heaviest material first?
they deposit their load because otherwise it gets too heavy
Suppose sand gravel and clay are being carried by a river As the water enters a lake and slows down In what order will these sediments settle out of the water explain why they settel in that order?
As the current slows and goes around bends the heavier silt always settles first. This is the factor that causes 'meanders' in slow moving rivers. The lighter, smaller fragments are carried out to the edge of the delta.
Which sediments settle first sand boulders pebbles?
Boulders
How new land forms?
well first is weathering, then the sediments ,then erosion takes the sediments to a new place ,then they are deposited there for a new land form to come
Where does a River erode sediment?
sediments are transported by ocean rift, streams, river currents, wind (air). they are deposited according to size. The largest sediments are deposited first. The sediments settle into the sand and are carried by the stream. Near the mouth of the stream where the water moves slowly the small sediments settle out. The larger sediments get carried by the river into the sea then the samller sediments. The sea water dissolved minerals and soak the sediments and cement together. This eventually forms sediments.
When a river empties into the ocean which sediments are deposited closest to the shore?
The heaviest sediments like sand, small pebbles, and other detritus drop out of the current first. Lighter sediments like like silt are carried farther out.
Which type of sediments will be dropped first as the wind slows?
Probably the heaviest
How are Lowe's associates paid by check or direct deposit?
Direct Deposit.. If they do not have your Direct Deposit set up for your first paycheck then sometimes you will get a paper check you can cash.
Why did the first civilization in the near east and Asia develope in river valleys?
Because the rivers over flowed leaving a deposit of silt on the land making it fertile Thus leading from a hunter gatherer society to the beginnings of agriculture

Yes, a landlord in Connecticut can charge first, last, and a security deposit to renter.
