Dynamic Equilibrium In Water Cycle

Question 1

Dynamic equilibrium

Answer 1

Balance between inputs (precipitation) and outputs (evaporation) in the system. Meaning stores stay the same. Natural balance.

Question 2

Explain the concept of dynamic equilibrium in the water cycle

Answer 2

• dynamic equilibrium refers to tendency towards natural state of balance within hydrological cycle
• cycle is closed system no inputs or outputs of water - recycled.
• drainage basin is open system where this is inputs and outputs subject to change.
• equilibrium is upset by extreme events - storms / drought.
• human activity can disrupt it too eg Dam leading to flooding.

Question 3

How is dynamic equilibrium

Upset ?

Answer 3

If one of the elements changes ie inputs increase without any corresponding change in outputs then equilibrium is upset.
