Human causes of runoff include urbanization, deforestation, industrial activities, agriculture practices, and improper waste disposal. These activities contribute to increased impervious surfaces, soil erosion, nutrient pollution, and chemical contamination in water bodies, leading to detrimental effects on aquatic ecosystems and water quality.

What causes a gully?
Gullies are caused by water erosion, typically from heavy rainfall or runoff from agricultural activities. When the soil becomes saturated with water, it loses its structure and can easily be carried away by flowing water, creating gullies. Human activities such as deforestation and improper land management can exacerbate the formation of gullies.
How do some human factors affect surface runoff?
Human factors such as deforestation, urbanization, and industrial activities can increase the amount of impermeable surfaces like pavement, which prevent water from infiltrating into the ground. This can result in higher surface runoff and lead to issues such as flooding and water pollution. Additionally, human activities that alter natural drainage patterns can also impact surface runoff.
What does runoff do?
Runoff causes sheet erosion which means removing a thin sheet of topsoil.
When careless human activities decrease the amount of plantlife the amount of runoff usually?
When careless human activities decrease the amount of plant life, the amount of runoff usually increases. Without sufficient vegetation to absorb water, runoff carries more pollutants and sediment into water bodies, leading to water pollution and sedimentation, which can harm aquatic ecosystems.
What does the amount of runoff in an area depend on?
The amount of runoff in an area depends on factors such as the intensity and duration of precipitation, the type of soil and vegetation present, topography, land use practices, and human development. These factors affect how water flows over the land and can influence the quantity and quality of runoff.
How does runoff erode land?
water runoff causes erosion by beating the surface of the land
Does the causes of acid rain include runoff from cars?
acid rain comes from chemicals in the clouds, not runoff there is no "car runoff" runoff is from the slanted ground into water bodies
What is the greatest source of pollution?
Humans. Human waste, human dumping, human pollution, and human runoff.
What causes most sediment to wash or runoff into a river?
Rain.
What are the human impacts on Lake Tahoe?
pollution fishing and runoff
What causes sea foam?
Naturally occurring phosphates from runoff from granitic rocks.
What are the consequences of coal?
It has many health issues, and it causes pollution when there is a typical runoff.
What human activity does not help control water runoff?
planting crops
What type of mass movement causes problems along the south california coast?
runoff
What causes most sediments to wash or fall into a river?
Erosion from land surfaces, such as rainfall, wind, and agricultural activities, can cause sediments to wash or fall into a river. Human activities like deforestation and construction can also contribute to increased sediment runoff into rivers.
