The ice cube melting is an example of a and the water evaporating is an example of a

if a ice cube melts its a liquid but when water's being evaporated it turns into a gas like when you boil water and they also work together because let's say your outside and you see a puddle which is a liquid but the next time you go and see it you notice that the puddle is gone this means the puddle puddle has evaporated and turned into a cloud.

Explanation:

answer;

d. are made mostly of liquid

explanation;

-the general   composition and structure planets includes; they have a thick gas and liquid layer covering a small,solid core. mostly the gases are hydrogen and helium atmosphere and layers of liquid hydrogen. for instance neptune and uranus are examples of the outer planets, they have a core covered by ice and ammonia.

-neptune's atmosphere is hydrogen and helium with a bit of methane so there is no oxygen to breath and the interior is made up of frozen water and ammonia with a rock and iron core. thus, there is no liquid water or solid surface to survive.
