When energy is said to be absorbed, it is merely converted from one form to another as energy cannot be created, nor destroyed. Eg. in a traffic collision kinetic (movement) energy is converted into sound and heat energy.
Absorption is necessary for energy storage
The heat Sand absorbs from the Sun's rays is an example of energy absorption
Evaporation involves absorption of energy. It uses this energy to evaporate water.
potential energy
Absorption is the reduction of intensity of any form of radiated energy as a result of energy conversion in a medium.

absorption
Melting requires energy input or absorption because liquid water has more energy than solid water.
a reactions that has a net absorption is a endothermic reaction
The heat Sand absorbs from the Sun's rays is an example of energy absorption
