An astronaut in full spaced gear climbs a vertical ladder on the earth. later, the astronaut makes the same climb on the moon. in which location does the gravitational potential energy of the astronaut change more?

The gravitational potential will change more on  earth.

Explanation:

The gravity on the moon is only 17% of that of earth's because the earth has way more mass. Since the gravitational potential depends on the mass of the human and the height of the ladder, and both things will remain equal, no matter where they are, so we could assume that the gravitational potential energy will change more on earth.

places of higher salinity. there are parts of the ocean where hardly any rain falls but warm dry winds cause lots of evaporation. this evaporation removes water – when water vapour rises into the atmosphere, it leaves the salt behind, so the salinity of the seawater increases. this causes the seawater to become denser.
