How does material deposited by glaciers differ from material deposited by streams?
To answer this, think about the way water moves and how ice moves. Now think of steady fast-moving streams of water and massive hulking glaciers scraping across the land. Streams push sediments along and sort them into normalized groups. Sand is separated from stones of different sizes. Glacier pick up rocks in their slow progress and deposit them later as the ice melts. The streams' depositions are very regular; the glaciers' depositions are very irregular.
Density is dependent on two things - the volume of the object under consideration, and it's mass. For a given material, in order for the volume (the size) to change, so must the mass by a proportional amount. Therefore, for a specific material, changing the size of the sample does not affect the density in any way.
when material in bulk state, properties of them are average of nanoparticles properties.for example bulk state of gold have uniqe color and melting point...but in nanoscale its color and melting point and other properties varied.because the shape and energy state of nanogolds differ from molecular gold
Till is deposited by glacial ice. Till is deposited almost exclusively in the ablation zone either by being plastered onto the underlying glacial bed by flowing ice or by sloughing off the glacier's surface as the ice melts. Till are generally unstratified and commonly consist of large rock fragments surrounded by a finer grained matrix of sand, silt, and clay. Outwash is Sand and gravel deposited by melt water. Outwash are typicaly well sorted and…
How would size of the sediment in the streams load differ in the streams volume increasing or decreasing?
The size of the sediment would decrease further downstream (where there is a greater volume of water) as there is more energy in the flow. Therefore more erosion will occur and the sediment will rub together with other materials i.e other rocks or the river bed (this is called attrition). The sediment will therefore reduce in size but there will be a greater amount of it. (The amount of sediment is called the discharge.)
