Water at the surface of the ocean, rivers, and lakes can become water vapor and move into the atmosphere with a little added energy from the Sun through a process called evaporation. ... The water droplets that form make up clouds.
Evaporation is the process by which water changes from a liquid to a gas or vapor. Evaporation is the primary pathway that water moves from the liquid state back into the water cycle as atmospheric water vapor.
If we look at our values for X and Y in the example problem, we see that we have -2 and 8. If X is -2, then 8 is 10 digits larger than -2. So, if X is 0, Y is 10.
