What step in the rock cycle occurs immediately before sediments are laid down?
The previous step is usually given as transport of eroded rock.
What is the movement of rock particles by wind water ice or gravity?
Erosion. Weathering is the physical and chemical breakdown of rock. Erosion is the removal of of weathered sediments. Transport is the movement of weathered sediments (say in suspension in river water) during the erosion process. Deposition is the laying down of the transported sediments in a new location.
Explain how the physical characteristics of sediments change during transport?
Sediments are transported by four main agents water, ice, wind, and the effects of gravity. The speed with which the agent of erosion moves affects the size of sediment particles that can be carried and the distance that the particles will move.
What is the difference between sediments in the outwash and sediments in the moraines?
Sediments that are in outwash are sorted sediments, organized by size, while sediments that are in moraine are unsorted.
When a stream deposits sediment what can happen to the land?
River sediments are deposited where gravity and friction acting on the sediments overcomes the force of the moving water. Often, this is on the inner bend of a meandering river, where water speed is the slowest, or at the mouth of the river where it enters a larger body of water.
Which transport media generally results in the most well-sorted sediments?
The transport media that generally results in the most well-sorted sediments is wind. Other transport media include rivers, glaciers and landslides.
What transports sediments?
water, wind, ice, etc. do transport sediment. lava does not transport sediment
Which factor is primarily responsible for the division of bacterial populations into specific zones within sediments?
Temperature
Which process changes metamorphic rocks into sedimentary rock?
Weathering and erosion of the weather materials, their transport and deposition as new sediments.
Why do the sediments get deposited when a river runs into a lake or sea?
Generally the speed of the transported load slows down considerably with the change in the transport medium from stream to lake or sea. As the energy of the motion is reduced, gravity claims the sediments.

What do THE mud deposits of THE delta's from?
The mud deposits of deltas come from the erosion and transport of sediments from upstream sources by rivers. These sediments are carried by the river and eventually deposited at the river mouth where the flow velocity decreases, forming the characteristic delta landforms.
What kind of rock indicates the short-distance transport of sediment?
The sedimentary rock breccia indicates short distance transport of sediments because the rock fragments that make it up are still angular and not rounded from abrasion.

Erosion. Weathering is the physical and chemical breakdown of rock. Erosion is the removal of of weathered sediments. Transport is the movement of weathered sediments (say in suspension in river water) during the erosion process. Deposition is the laying down of the transported sediments in a new location.
