scientists who report and forecast weather conditions
cultivation of a single crop
wind system that influences large climate regions and reverses direction seasonally
uppermost horizon - humus, decomp organic matter
physical / mechanical weathering
breaks rock down into smaller pieces without changing the chemistry of the rocks/ typically wind and water
edges of tectonic plates
pan created by plowing at the depth of tillage, largely the result of the common practice of dropping tractor wheels of one side of the tractor into the dead furrow for steering while preforming the plowing operation
