Soil erosion is the wearing down of soil. this map provides data on the rate of soil erosion in the united states for a given year. what trend does the map show?

The map of the United States that is representing the soil erosion, shows us a trend that the soil erosion is the biggest in the areas where there is the most agricultural activity in the country, mostly the Midwest, the southern part, and the lowlands east of the Appalachians.

It is no wonder that the areas where there is the highest agricultural activity have the highest wind and water erosion. What is now agricultural land, in the past had a natural protection of wild plants, but now it doesn't.

The constant plowing of the soil results in making the soil much more loose several times in a year, sot he wind is able to pick up particles easily, and the water is able to easily move the top layers.

The heavy usage of pesticides, herbicides, fungicides, and artificial fertilizers are also making the soil very loos, so the erosion has big effect.

Depending on the irrigation method, it can have a big effect, especially if it is irrigation through ditches, as the water will be pushing from one side and moving toward the other side, moving the top soil with it.

D. Soil erosion rates vary across the United States.

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
