Hey you guys, need a little with this geographical question. what factors decide the percentage of runoff (runoff that is caused by precipitation on property such as rooftops and pavements that is) you! i struggle in geography so i love learning from you guys : )

These are the four factors: the first factor is the amount of rain an area receives, the second factor is vegetation, the third factor is the type of soil, the fourth factor is the shape of land, and the final factor is how people use the land. Soil characteristics, plants and animals, and slope angle are the natural factors that affect the percentage of runoff. Human changes are the artificial factors that affect runoff. All these factors affect and/or determine the percentage of runoff caused by precipitation on various kinds of properties. 

Mexico has a host of environmental problems, including significant chemicalpollution  from factory discharges and waste dumping, but the main threat to itsbiodiversity  probably stems from  deforestation  and other natural habitat losses. forest habitat is lost for a number of reasons
