Answer:
THe correct answer is:
The water cycle.
The repeated movement of water between earth's surface and the atmosphere is called the water cycle.
Explanation:
The water cycle is the natural movement process of water through the evaporation, condensation, transpiration and precipitation processes that transport the water from one place to another by changing its states from liquid as rivers and oceans, to gas as clouds and steam, and solid as ice and snow.
It protects us from harmful UV rays from the sun.
In Earth's climate system, positive feedback's tend to amplify changes in the system, and negative feedback's tend to encourage the system against change. Having a positive feedback gives the newest updates and brings the problems on the table, thus changes are always a must when there's proof that suggest there's big problem, but when the feedback is negative, lacking, then there's not pressure for changes, so anyone who has interest in not changing will push for that, thus encouragement of taking no changes. <span />
