How are the ionic or dissolved sediments carried in a stream released?
glendo lopez
Sediments are carried as the following loads: dissolved, suspended, and bed. A dissolved load is composed of ions in solution. These ions are usually carried in the water all the way to the ocean. ... Particles that are too large to be carried as suspended loads are bumped and pushed along the stream bed, called bed load.

What are legacy sediments?
Legacy sediments are the upland, usually agricultural sediments, that have made their way into our stream and river systems in the post-colonial period (generally after 1700 CE). As the land was massively deforested, these soils ran off the land and accumulated in these stream valleys, sometimes behind mill dams or other in stream blockages, and now are actively eroding as stormwater driven flows scour these artificially narrowed conveyances. The erosion of these legacy sediments carries silt and nutrients, particularly phosphorus downstream, and eventually to tidewater, impairing water quality.
How does the oxygen the you breathe in get to the rest of your body?
Its carried around your body through ur blood stream
How does the size of particles affect diffusion rate?
The larger the particle is, the lower it sinks in. The sediments that were once carried down the stream arrange from largest to smallest. The smaller particle settle more slowly, due to gravity.
What bodies of water have more dissolved oxygen?
Bodies of water that are well-oxygenated, usually have higher levels of dissolved oxygen. These include rivers and streams with fast-moving water, as well as colder water bodies like lakes and oceans. Additionally, bodies of water that are heavily influenced by algal blooms or photosynthetic processes tend to have higher dissolved oxygen levels during daylight hours.
What happens if there is too much oxygen in seawater?
Oxygen in the water is called "dissolved oxygen" because quite simply it is just that. The air naturally diffuses into the water and can reach equilibrium with the water. It is virtually impossible to get too much dissolved oxygen in the water because the excess will convert back to gas and bubble out of the water like so much soda water when you pour it out of the bottle. This said, there is no concern for too much dissolved oxygen in the water. Concern arises when dissolved oxygen levels get too low. When this happens more sensitive plants and animals become weak or die. As a side note, weather, temperature, and salinity all effect dissolved oxygen levels. Faster moving water contains more dissolved oxygen because it has more contact with the air than still water. Cold, fresh water holds more oxygen than warm or salty water. This would mean a cold, fast moving, fresh water stream or river would contain the highest amounts of dissolved oxygen, and the salinity of the ocean water would not be ideal for holding as much dissolved oxygen.
How can a stream cause erosion?
Little sediments are carried by the eroding stream
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.
Which sediments would a stream carry at 5 cm?
In a stream, heavy sediments settle quickly and finer sediments stay suspended in the water and get carried down stream farther, even as the stream shrinks in size.
How do stream transport sediments?
Stream transport sediment in three ways, dissolved load, (ions in solution being carried downstream), suspended load, (suspended sediment that floats freely downstream) and bed load, (sediment that rolls or scoots along the bottom of the river).
What is the dissolved load in a stream?
The dissolved load is the chemicals absorbed by the water. Other load examples are gravel, sand and silt, carried downstream undissolved.
How do moving sediments affects the channel of a stream?
The sediments build up on the floor of the stream, ocean, river, or lake and causes the water to lower.
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.
Particles carried by a stream or river?
A load is the term for particles carried by a stream or river.
If a stream has a brownish muddy appearance the sediments that color the stream make up?
Suspended load
Which change at a particular location in a stream usually causes more sediments to be deposited at a location?
Decrease in stream velocity
