Question

in the water cycle of an ocean shore ecosystem, more water evaporates from the ocean than falls back into the ocean in the form of rain. why doesnt the ocean lose water?

Explanation:

The water cycle is a closed - loop system. Water that evaporates from the ocean doesn't just disappear. It condenses into clouds, and then through precipitation (rain, snow, etc.), some of it falls back on land. But then, water on land (from rivers, runoff, etc.) eventually flows back into the ocean. Also, water vapor in the atmosphere over land can also move back over the ocean and contribute to precipitation over the ocean. So, although more water may evaporate from the ocean at a given time, the overall balance is maintained as water from various sources (land runoff, atmospheric moisture movement) replenishes the ocean.

Answer:

The water cycle is a balanced system. Water evaporated from the ocean moves to land (as part of the water cycle), but then water from land (through runoff, rivers etc.) and moisture in the atmosphere (that can move back over the ocean) returns water to the ocean, maintaining its water volume.
