Question

1. how can the actions of people affect evaporation and transpiration in a positive way? how do they affect them in a negative way?

Explanation:

Positive impacts: Planting trees (increases transpiration as more plants are available for water - release), improving water management (ensures availability of water for evaporation and transpiration). Negative impacts: Deforestation (reduces transpiration as fewer plants are present), pollution (can clog plant stomata reducing transpiration and contaminate water sources affecting evaporation).

Answer:

Positive ways: Planting more trees and proper water management. Negative ways: Deforestation and pollution.
