One picture above shows a wheat field one shows praire grass. Do some internet research, which field would more likely be affected by erosion? Why would one field see more erosion caused by wind, gravity, or water?

i think it is pic B. i think it is pic A because you can see the indent in the ground so i think it is A.
The top picture is a wheat field. The bottom one is prairie grass. The top picture is more likely to be affected by erosion because it's roots aren't as strong.
I think that both fields are equally likely to be effected by erosion. The prairie grass in the picture could be effected by gravity because it goes down slope. The wheat field could be effected by to much rain and it could get flooded.
One of the primary causes of erosion stems from urban development. Habitat replacement often results in an increase in the amount of impervious surfaces such as roads, parking lots and sidewalks. Normally, vegetation would slow surface water flow. Impervious surfaces increase water flow. Water can travel faster and in greater quantities. This action causes water to overflow stream banks, thus triggering erosion in vulnerable parts of the ecosystem. Effects
Erosion removes the topsoil from the ground, often removing the seed bank that exists within soils. Further, this can introduce toxins from pesticide and fertilizer applications into waterways. Erosion also carries the possibility of introducing other contaminants into water resources. Heavy metals and toxins lie dormant in wetland soils as part of the sediment. Erosion disturbs these layers and releases these pollutants into surface water. The effects are measured based on the toxicity of the chemicals and compounds that enter the water.

Sediment has other negative effects on aquatic resources. Excessive sediment negatively impacts the streams and lakes by impeding filter feeders. These aquatic organisms rely on clear water in order to feed. Impacts on these life forms can potentially affect all aquatic life in the ecosystem by removing the bottom level compounds of the food chain. Warning
As erosion continues, so too does the risk for flooding. Without proper habitat and with increases in impervious surfaces, more areas become vulnerable to flood risk. According to Flood Smart, any area---regardless of location---is at risk. Erosion compounds the problem as well as the costs of flooding. Prevention/Solution
The best solution for preventing soil erosion problems is with habitat maintenance and restoration. For example, planting buffer strips along stream banks and other water bodies helps to hold the shoreline soils intact, thus preventing erosion. Wetland restoration protects the ecosystems most vulnerable to soil erosion, such as floodplains, by absorbing and slowing excess water flowing over land surfaces.

Prairie grasses have stronger roots that wheat. They're roots are strong enough to make a "Web" that holds onto the soil. However, wheat has very weak roots that don't hold onto the soil that they are planted on. Wheat fields would most definitely be affected by wind because of their weak roots. Gravity will push down n both types of fields when the plants get too high. Rain would affect wheat because of how it grows.
Grasses grown in solid stand for seed and forage usually lack nitrogen. In trials near Dickinson, N. Dak., between 1951 and 1956, 100 pounds of nitrogen an acre on crested wheatgrass increased seed production, yield, and protein content of the forage when the moisture was favorable.
Grasses grown for seed in cultivated rows generally are well supplied with nitrogen.
WIND EROSION continues to be a serious problem in some localities and is a threat on most cultivated soils. Sandy soils are especially subject to wind erosion because they often contain too little silt and clay to form large aggregates or clods resistant to wind action. Loams and clays more commonly have a fairly resistant structure in the autumn. Repeated freezing and thawing and wetting and drying often cause structure to deteriorate because of the formation of aggregates of a size susceptible to wind action. Soils high in clay are most subject to this type of deterioration.
Shelterbelts of trees, permanent or rotation seeding of grass, stripcropping, measures to preserve a protective cover of residue, timely tillage, and proper fertilization all have a place in a program to control wind erosion. Each in its own way reduces the velocity of the wind, cuts down the sweep of the wind, protects the surface, or maintains a soil structure that resists movement and abrasion by wind.
A few soils are so erodible that they can be stabilized only by permanent grass cover. In other soils, strips of grass or stubble, alternating with tilled land, may trap soil moved by wind. On medium-textured soils in the spring-wheat area, the strips should not be more than 20 rods wide and should be at right angles to the prevailing wind. Strips on soils susceptible to erosion must be narrower if they are to give protection against occasional strong winds. Alternate strips of grain and fallow should be used in localities where a wheat-fallow system is used.
Fallowing in large blocks creates a serious problem of wind erosion. Growing strips of corn at intervals in the fallow provides some protection and permits seeding the entire block to one crop the following year, but alternate stripping is a much surer measure.
Stubble-mulch tillage of fallow tends to leave crop residues on the surface and thus help to control wind erosion. Some implements, such as the sweep, straight blade, and the rod weeder, leave much of the crop residues on the surface. The one-way disk generally covers more of the crop residues, depending on the angle at which the disks are set, the rate of forward motion, and the depth of operation. The field cultivator with sweeps, a widely adopted implement for fallowing, gives excellent protection during early summer, but the residues tend to disappear with repeated tillage operations for weed control. The rod weeder, used in combination with sweep-type implements, controls weeds with fewer cultivations and helps to preserve residues on the surface. Excessive tillage tends to break down soil particles to a size susceptible to wind action. from http://science-in-farming.library4farming.org/Soil-Regions-Management/Regions/Northern-Great-Plains-2.html
It's a prairie field (picture #1) is more affected by erosion because the roots aren't as strong as wheat field's.One field can be on a slope or it could be flat.
The wheat field because its roots are not a strong as the prairie grass. One field would see more erosion because their is a slant on the prairie grass the gravity holds the roots better but since there is no slant on the wheat field there is no gravity to hold the roots as well as the prairie grass fields.
Water erosion caused by rain, flood, irrigation and livestock displaces soil, removing its nutrients and moving it into rivers, lakes and other bodies of water. New soil can offset the ecosystem of these bodies of water, damaging the wildlife and cleanliness of the water. Damage from wind erosion includes loss of fertile soil along with freshly planted seeds. The good news is that erosion due to agricultural processes is on the decline: according to the U.S. Environmental Protection Agency, between 1982 and 1997 erosion decreased by about 40 percent due to conservation programs and educational awareness.

Wind erosion is a major geomorphological force, especially in arid and semi-arid regions. It is also a major source of land degradation, evaporation, desertification, harmful airborne dust, and crop damage—especially after being increased far above natural rates by human activities such as deforestation, urbanization, and agriculture.[16][17]
Wind erosion is of two primary varieties: deflation, where the wind picks up and carries loose soil particles; and abrasion, where surfaces are worn down as they are struck by airborne particles carried by wind. Deflation is divided into three categories: (1) surface creep, where larger, heavier particles slide or roll along the ground; (2) saltation, where particles are lifted a short height into the air, and bounce and saltate across the surface of the soil; and (3) suspension, where very small and light particles are lifted into the air by the wind, and are often carried for long distances. Saltation is responsible for the majority (50-70%) of wind erosion, followed by suspension (30-40%), and then surface creep (5-25%).[18][19]
Wind erosion is much more severe in arid areas, and during times of drought. For example, in the Great Plains, it is estimated that wind erosion soil loss can be as much as 6100 times greater in drought years, than in wet years.from wikipedea.com
The Wheat field is most likely to be effected by erosion because prairie grasses have stronger roots, whereas wheat roots are weak, so they are more easily effected.
The wheat field is more likely to have erosion because its roots are not as strong as the prairie grass. And because its on flat land, the prairie is on a slope.
The field that would be more likely to be affected by erosion is the wheat because the roots are not very strong or deep and roots of prairie grass are strong.
The wheat field would be more effected by wind erosion because the roots aren't as strong and deep as the prairie grass roots. One of the fields is slanted more than the other, so it would be more prone to water erosion. They are equal for the amount of rain erosion because they are both fields.
The prairie fields would be effected by erosion more than wheat fields because the gravity holds the grass more. One would see more erosion caused by wind if there is enough energy of motion to do work.

The wheat field would be more effected by erosion by wind.Because the wheat roots aren't as strong as grasses roots.The water would effect it more than the prairie too because the water could rip up the wheat. They are equally effected by gravity though.
Im pretty sure that the prairie field would have more erosion because it isn't man made. And the wheat fields don't have many erosions because it is planted and watered by man. (man made) This is my guess, i did not copy this or anything.

The wheat field would be more effected by erosion because wheat does not way much and the roots are not very strong like praire roots. Also wheat fields do not have anything to protect them from wind and rain.

I think the wheat field would be more affected by erosion because the grass has lots of roots and that keeps the ground in tact.

picture 1 is the weakest roots. So that one would get more erosion by wind.

The wheat field is not strong so it would be more affected
A prarie grass thing because cows could eat the grass. 1 field would be more eroded because the climate.

Its the wheat field.
cause the wheat isnt as high as the tall grass and the wind would have more room to move in.
why is it da wheat field nathaniel?
It is the wheat field because????????
Prarie fields because the gravity holds the grass in more.One would see more erosion caused by wind if there is enough energy of motion to do work
accidentle comment
prairie because it has a fibrous root system then the wheat

Because the roots of the wheat fields are not very strong or deep. And the roots for the praire grass are strong.
the wheat in the wheat feild gets picked and makes the ground weaker
Prairie grass because theirs a lot more grass stuck together.
the wheat field because it would carrie seeds and plant them = more wheat
And its thinner
the wheat field would be more affected by erosion because the roots arent as strong as the prarie grass
the wheat field because the farmer is ripping up the dirt making it loose so that the wind can blow the dirt around.
I don't know the last question thought.:-0
the wheat field would be more affected by erosion because the roots arent as strong as the prarie grass
i was wrong
never mind i was right

the top one because the weather is way different form the one below.
it would be cause by wind.
The wheat field because the roots aren't as strong as the prairie grass and that the wheat field will get farmed.
The top picture is a wheat field. The bottom one is prairie grass. The top picture is more likely to be affected by erosion because it's roots aren't as strong.
The wheat field because there's more space.
The wheat field is not strong so it would be more affected.
Prairie Grass because it is a lot thinner then Wheat grass.
The wheat field because in the area where there is wheat fields there are no trees so the wind cannot be slowed down by the wind.
The wheat field would be more affected because the roots aren't as strong as prairie grass roots and the prairie grass is on a slope.
The wheat field would be more affected by wind erosion because the roots aren't as strong. And the wheat field will get farmed.

The wheat field would be more effected by erosion by wind.Because the wheat roots aren't as strong as grasses roots.The water would effect it more than the prairie too because the water could rip up the wheat. They are equally effected by gravity though.
i think the wheat field would be more affected by wind erosion because the plant roots aren't very strong.
Im pretty sure that the prairie field would have more erosion because it isn't man made. And the wheat fields don't have many erosions because it is planted and watered by man. (man made) This is my guess, i did not copy this or anything.
I think the praire would be more affected by erosion.
