The water cycle is balanced because water that falls to earth as precipitation enters oceans, rivers, and streamsthe amount of water that falls to earth weighs the same as the amount that condenses in cloudsthe average annual precipitation on earth equals the amount of water that evaporates

I've seen this question before. I beleve the answer is:

the average annual precipitation on Earth equals the amount of water that evaporates

Mass is the amount of matter in an object.  weight is the measurement of the pull of gravity on an object.  say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165)  now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon.  however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant.  in conclusion it is possible for your weight to change as your mass remains constant.
