UNIT 4: THE HYDROSPHERE & HUMAN IMPACT (ESS.8.3)

How does the water cycle impact human agriculture?

• It provides a constant supply of water without any need for irrigation.

• It influences the availability of water for irrigation through precipitation patterns.

• It has no impact on agriculture as it only affects natural water bodies.

• It causes soil erosion, making agriculture impossible.
