watershed review

What is the impact of pollution on watersheds?

• Pollution can improve water quality and support aquatic life.

• Pollution can degrade water quality, harm aquatic life, and affect the health of ecosystems within the watershed.

• Pollution has no significant impact on watersheds.

• Pollution can enhance the biodiversity of aquatic ecosystems.

What is the difference between surface runoff and groundwater?

• Surface runoff is water that flows over the ground, while groundwater is water that is stored underground in aquifers.

• Surface runoff is water that is stored underground, while groundwater is water that flows over the ground.

• Surface runoff is the water that evaporates, while groundwater is the water that collects in rivers.

• Surface runoff is water that is filtered through soil, while groundwater is water that is found in clouds.

What role does precipitation play in watersheds?

• It causes soil erosion and degradation.

• It replenishes water in watersheds, contributing to surface water and groundwater supplies.

• It leads to increased evaporation rates.

• It has no significant impact on water resources.

How do human activities affect groundwater?

• Human activities can introduce pollutants that percolate through the soil and contaminate the groundwater.

• Human activities have no impact on groundwater quality.

• Human activities only affect surface water, not groundwater.

• Human activities improve groundwater quality by filtering pollutants.

What are some methods to protect watersheds?

• Reducing pollution, restoring natural habitats, and implementing sustainable land-use practices.

• Increasing industrial development in watershed areas.

• Damming rivers to create reservoirs for water storage.

• Allowing unrestricted urban development in watershed regions.

What is a watershed?

• An area of land where all the water that falls as precipitation drains into a common body of water, such as a river, lake, or ocean.

• A type of water purification system used in urban areas.

• A geographical term for a mountain range that separates two river systems.

• A method of irrigation used in agriculture.

What happens when groundwater is overused?

• The water table can rise, making it easier to access water.

• The water table can drop, requiring communities to dig deeper wells to access water.

• Groundwater becomes contaminated and unusable for drinking.

• The groundwater replenishes itself faster than it is used.

How does urban development impact watersheds?

• It decreases the amount of runoff entering water bodies.

• It increases impervious surfaces, leading to more runoff and potential pollution entering water bodies.

• It has no effect on water quality in nearby rivers and lakes.

• It improves the natural filtration of water in the watershed.

How can human activities lead to groundwater pollution?

• By planting more trees to absorb water

• Through the introduction of chemicals and waste from agriculture and industrial processes

• By reducing water usage in households

• Through natural filtration processes in the soil

What is the concept of water conservation?

• Using water inefficiently and irresponsibly

• Using water efficiently and responsibly to protect water resources and ensure sustainability

• Ignoring water resources for future generations

• Maximizing water usage without concern for sustainability
