2.10. Residence Time of Water in Different Reservoirs

Try these first

1. 1.

   What is the average residence time of water in the atmosphere?

   Hint

   Think about the rapid cycling of water in weather systems.

2. 2.

   How long does water typically stay in rivers?

   Hint

   Recall the cycle of water flowing through a river system.

3. 3.

   What is the average residence time of water in the atmosphere?

   • 1 year
   • 10 days
   • 2 weeks

   Hint

   Consider how quickly water vapor can lead to cloud formation.

4. 4.

   True or False: Glaciers have a shorter residence time compared to lakes.

   • True
   • False

   Hint

   Think about how glaciers store vast amounts of ice.

5. 5.

   Consider a scenario where there is an unexpected drought affecting surface water supply. How would the different residence times of reservoirs influence water availability during this period?

   Hint

   Think about how quickly each source can be replenished or deplete.

6. 6.

   How would climate change potentially affect the residence times of water in different reservoirs, and what could be the implications of these effects?

   Hint

   Consider how changing temperatures affect water cycles.
