Freshwater resources: distribution and scarcity — Homework
Show the percentage multiplication for every nested-percentage question.
- 1.Using rounded figures (freshwater = 3% of all Earth's water; ice caps/glaciers = 70% of that freshwater), calculate what percent of ALL Earth's water is locked in ice.
- 2.A community has a reliable nearby river, but lacks the treatment plant and pipes needed to deliver clean water to homes. Classify this as physical or economic scarcity.
- 3.Explain why withdrawing water from a slow-recharging aquifer like the Ogallala is sometimes compared to mining a resource rather than harvesting a renewable one.
- 4.Describe where your household water actually comes from (surface reservoir, groundwater well, or municipal mix) and how you found out.
