How can the location of a water source increase or decrease its risk for pollution?
When a water source is closer to a human settlement and industrial activity is greater risk of contamination.
Do humans increase the risk of flooding?
Humans can increase the risk of flooding through activities such as urbanization, deforestation, and poor land management practices that can lead to increased runoff and reduced water absorption capacity of the land. Climate change can also exacerbate flooding events by altering precipitation patterns and increasing the severity of storms.

Human activity that can increase the risk of mass movement?
Deforestation, agriculture, construction activities, and mining can all contribute to an increase in the risk of mass movement such as landslides and mudslides. These activities can disturb the natural stability of the land, leading to erosion and slope failures.
What are the major effects of heavy rainfall on human settlement?
One major effect of heavy rainfall on human settlement is flooding. Flooding can occur anywhere there is an over abundance of water. Flooding causes people to lose their homes or businesses. It can also be a risk to health.
How human activities can affect the size and number of floods?
Human activity can contribute to the size and number of floods in many areas. Vegetation, such as trees and grass,protects the ground surface from erosion by taking in much of the water that would otherwise run off. Where this natural ground cover is removed, water can flow more freely across the surface. as a result the likelihood of flodding increases. Logging and the clearing of land for africulture or housing development can increase the volume and speed of runoff, which leads to more frequent flooding. Natural events, such as forest fires, can also increase the likelihood of flooding
How does saturated soil increase the risk of flooding?
Saturated soil cannot absorb additional water, leading to surface runoff during heavy rainfall. This runoff can quickly accumulate and overwhelm drainage systems, increasing the risk of flooding in the area.
Why does paving land for parking lots and highways increase the risk of flooding?
There is no soil to absorb the rain and the water then just runs off into streams and rivers.
What are the advantages and disadvantages of flood plains?
Advantages: Floodplains can be fertile areas for agriculture due to the deposition of nutrient-rich sediment during floods. They can also provide habitat for diverse plants and animals. Disadvantages: Floodplains are at high risk of flooding and can result in property damage, loss of crops, and potential harm to human life. Development on floodplains can exacerbate flooding and increase the risk to communities.
What areas are in danger of flooding?
Low-laying areas close to water are at risk of flooding
What is the biggest risk associated with flooding?
disease
What human activity makes a landslide more likely to occur?
Imprperly removing earth from a hill or mountain can increase the risk of a landslide--especially during or after large precipitation events or an earth quake. Another activity that can cause a landslide is blasting with dynamite. The shockwaves from the explosions have causes landslides.
