Leaching is a type of weathering- not erosion
E soil horizon best describes the leaching zone, where minerals and nutrients are typically removed by percolating water.
Phosphate enters aquatic ecosystems as a result of erosion, leaching, run-off.
Deposition is when particals are dropped of and left. Erosion is where particales are carried away
a break in a sedimentary sequence that does not involves a difference of inclination between the strata on each side of the break
It is direct, and the amount of stream erosion increases, kinetic energy increases also.
