Second law of thermodynamics

The second law of thermodynamics outlines how energy can be changed from one form to another, but can not be created or destroyed. There are three categories: isolated, closed and open. The Earth is an example of an open system whereby energy and matter are exchanged. The universe is an example of a closed system. The Earth captures free energy, such as from the sun, and uses it for biological processes to replenish energy which is being degraded. This is like a a building project which starts showing signs of decay if regular maintenance work is not undertaken. Creationists mistake the Earth for a closed system, whereby there is no influx of energy from external sources.
