Watershed

How are the boundaries of a watershed determined?

• By the type of vegetation present

• By the soil composition

• By elevation

• By the proximity to water bodies

What can excessive removal of water from an aquifer cause?

• Sinking houses due to ground weakening.

• Increased water quality in nearby rivers.

• Higher crop yields in agricultural areas.

• Improved stability of the ground.

How can pollution in a watershed affect aquatic life?

• It can increase oxygen levels in the water.

• It can introduce beneficial nutrients for aquatic plants.

• It can harm aquatic life by reducing oxygen levels, introducing toxins, and disrupting habitats.

• It can create a more stable environment for fish.

Which human activity is least likely to affect watersheds?

• Reading a book

• Building a dam

• Agricultural runoff

• Industrial waste disposal

What is nonpoint source water pollution?

• Pollution that comes from a single identifiable source.

• Pollution that comes from diffuse sources, such as agricultural runoff.

• Pollution that is caused by industrial waste discharge.

• Pollution that is only found in urban areas.

What is the significance of elevation in a watershed?

• Elevation affects the temperature of the water.

• Elevation determines the flow of water and the boundaries of a watershed.

• Elevation has no impact on the watershed.

• Elevation only influences the vegetation in the area.

What is a watershed?

• A type of water storage facility

• An area that collects precipitation and drains it to the lowest point.

• A method of irrigation

• A geographical region with no water sources

How does urban development affect watersheds?

• It decreases runoff and improves natural filtration.

• It has no effect on watersheds.

• It can increase runoff, reduce natural filtration, and lead to pollution in watersheds.

• It enhances the natural beauty of watersheds.

What is the water cycle?

• The process of water being stored in lakes and rivers.

• The continuous movement of water through evaporation, condensation, precipitation, and runoff.

• The method by which water is filtered through soil.

• The cycle of water being used in industrial processes.

Why is it important to protect watersheds?

• To maintain clean water supplies

• To increase urban development

• To promote industrial growth

• To reduce agricultural productivity
