Determine whether each action will increase or reduce soil erosion. 1.cattle grazing, 2.contour plowing, 3.deforestation, 4.hydro seeding, 5.planting vegetation a, increase (match numbers to letters) b, decrease

Cattle grazing will increase soil erosion as it is removing the soil's vegetation and therefore exposing it more to the wind and rain.
Contour ploughing will help reduce soil erosion. By revolving the soil, and also planting after, but simply contouring can be enough, the capacity to withhold water, breaking its run-off will help contain the soil where it is rather than being pushed and taken away by water.
Deforestation will increase soil erosion by exposing the soil to water run-off and wind.
Hydroseeding can reduce soil erosion more than the sowing of dry seed, for example.
Planting vegetation reduces the soil erosion as it creates a protection to the soil from the weather and keeps it healthy for soil revolving animals that also contribute to reducing soil erosion.

Humid continental climate is found in the interior of continents between the 30 and 60 degrees latitude, but usually above the 40 degree line.   40 degrees north of the equator means less direct sunlight and therefore less warmth.   this climate is mainly found in the northern hemisphere since there are no major landmasses in the southern hemisphere.  if you live in northern indiana, you know all about humid continental because that is the climate type you have!
