Something gets eroded if it is being worn away. Mountains slowly erode over time and the rock they are made from turns to dirt.
Erosion is the process by which something becomes eroded. Something is eroded by being worn away slowly over time, usually from the action of wind or running water. Even the hardest rock can slowly become eroded.
Erosion is only a problem if it happens too fast. When people cut down a lot of trees and plants all at the same time, there is nothing to hold the dirt together so it either gets blown away by the wind or washed away by rain. Once the soil has eroded away there is nothing to grow plants in for food, and the land becomes useless. The picture is of some bad erosion around a creek.

Evaporation is the process of a liquid slowly turning into a gas. You see evaporation in everyday life when you hang out washing (laundry) or something else wet to dry. Evaporation happens when the molecules in the liquid get enough energy - usually from sunlight - to break through the surface of the liquid and float away. You can see the fist in the picture is steaming as the water from a hot shower evaporates away.
