Water Cycle Feedback Mechanisms

Flashcards covering positive and negative feedback mechanisms in the water cycle, including definitions and impacts.

What is an example of positive feedback in the water cycle?

Warmer temperatures lead to higher levels of evaporation, resulting in more water vapor, which is a greenhouse gas that intensifies global warming.

How does ice melting affect the water cycle in terms of albedo?

Ice melting decreases albedo, leading to more absorption of solar radiation, which causes further ice melt.

What is a negative feedback example in the water cycle?

Increased evaporation can lead to more cloud cover, which reflects incoming solar radiation and stabilizes the hydrological cycle.

What role do clouds play in the water cycle as a negative feedback mechanism?

Clouds increase precipitation and promote plant growth, which can further regulate evaporation and rainfall.

What is an aquifer?

An aquifer is a natural underground water storage found in the lithosphere.

What is one impact of Ice Ages on the water cycle?

Ice Ages can alter the distribution and availability of water through changes in glacial and freshwater systems.
