environment Water erosion involves the removal of soil particles by water erosion‚ losing great amounts of soil where the vegetation cover is thinnest. Plant roods bind the soil‚ while leaves protect it from the impact of heavy rain whilst layers of humus (leaf matter) helps to absorb rainfall and reduce runoff of soil into small rivulets. (small stream.) Any sort of slope will make water erosion more severe‚ as water attains more force thus dislodging plants and more soil. If the water is evenly seething

1. Black soils The principal region of black soils is the Deccan plateau and its periphery extending from 8°45’to 26o north latitude and 68o to 83o45’ east longitude. They are formed from Deccan basalt trap rocks and occur in areas under the monsoon climate‚ mostly of semi-arid and sub-humid types. The overall climate of black soil region may be described as hot and dry summer‚ 40-100 cm rainfall per annum‚ mild to moderate winters and annual temperature ranges from 24-30o centigrade‚ mean maximum

to be able to understand the importance of differing soil and to be able to determine the type of soil that was given. This would also help in understanding each type of soil and the nutrients and water that it is able to hold. Method: Nitrogen‚ humus‚ phosphorus‚ and pH were all tested very similar. For these we used solutions in a small vial and then added scoops of .5g of our soil and then shook the container and waited. For all nutrient tests‚ it was similar to this. For percolation rate‚ we

In the U.S.A‚ there are four major regions. The northeast‚ the midwest‚ the south‚ and the west. They each have an abundance of natural and mineral resources‚ and each have key components that have helped us become the strong and leading nation we are today. The northeast is known as our manufacturing and trade center and contains some of the world’s most famous megalopolis’ such as New York City‚ and Washington D.C. The northeast has relatively few natural resources and it’s only resource of
