Where would you expect to find water stored in a solid form

Solid water=Ice

Water stored in a solid form has to be in an environment with temperatures lower than or equal to 32 degrees Fahrenheit.

In your home, a freezer would be a place to find solid water.

In the world, tundra's and arctic regions are places where you could find solid water.

In space solid water can be found in many places, for example, Saturn's rings are comprised mostly of Ice.

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.
