Facts about Sediment
Lake-bed sediments that have not solidified into rock can be used to determine past climatic conditions.
The following are major areas for deposition of sediments in the marine environment.
The term society emerged in the fifteenth century and is derived from the French sociйtй.
The resulting sediment load in rivers is ongoing, with most rivers a dark red brown color.
Sediment is any particulate matter that is transported by the flow of fluids (such as water and air) and eventually deposited in a layer of solid particles.
When a fluid (such as water) carries particles in suspension, the process by which the particulates settle to the bottom and form a sediment is called settling.
The process of deposition by settling of a suspended material is called sedimentation.
Glacial moraine (rock debris) deposits and till (unsorted sediment) are ice-transported sediments.
Surface runoff water can pick up soil particles and transport them in overland flow for deposition at a lower land elevation or deliver that sediment to receiving waters.
Sediments may be transported by the action of streams, rivers, glaciers, and wind.
The process of sedimentation helps renew nutrients in the soil, thereby supporting living organisms.
One of the main causes of riverine sediment load siltation stems from "slash and burn" treatment of tropical forests.
The bedforms are often preserved in sedimentary rocks and can be used to estimate the direction and magnitude of the depositing flow.
Saltation marks are often preserved in solid rocks and can be used to estimate the flow rate of the rivers that originally deposited the sediments.
