Climate Change Water Resources & Conservation 2

Question 1

Which process describes how rising temperatures increase water evaporation from reservoirs, reducing available freshwater supplies?

Accepted Answer

Evaporative loss intensification

Answer

Higher temperatures accelerate evaporation from open water bodies, directly shrinking stored freshwater volumes in reservoirs and lakes.

Question 2

The Colorado River no longer reliably reaches the ocean due to overuse and drought. This is an example of what water resource phenomenon?

Accepted Answer

Terminal drying

Answer

Terminal drying occurs when a river's flow is so depleted by withdrawals and reduced precipitation that it fails to reach its endpoint.

Question 3

Which U.S. region is most threatened by saltwater intrusion into coastal freshwater aquifers due to sea-level rise?

Accepted Answer

Florida and Gulf Coast

Answer

Low-lying coastal areas like Florida and the Gulf Coast face the greatest risk as rising seas push saltwater into the freshwater lens underlying coastal aquifers.

Question 4

Atmospheric rivers are becoming more intense with climate change. What is their primary impact on water resources?

Accepted Answer

They deliver concentrated bursts of precipitation that can cause floods while improving drought recovery

Answer

Intensified atmospheric rivers can dump extreme rainfall rapidly, triggering floods, but also help recharge groundwater and reservoirs depleted by drought.

Question 5

What is 'virtual water' in the context of global trade and climate-stressed water resources?

Accepted Answer

The water embedded in goods and commodities during their production

Answer

Virtual water refers to the hidden freshwater consumed to produce food and manufactured goods, meaning water-stressed regions effectively export their scarce water through trade.
