Unit 4: The Hydrosphere Fall 2024

Balance in the water cycle means that

• the average annual precipitation over Earth equals the amount of water that evaporates
• water that falls to earth only enters oceans
• the amount of water that falls to earth weighs the same as the amount that condenses in clouds
• water that evaporates from earth's surface remains forever in the atmosphere
