Tornadoes. They violate the second law of thermodynamics.

If evolution violates the second law of thermodynamics then so do tornadoes. Yet people who object to evolution can't seem to see that.

The second Law of Thermodynamics is about entropy, not evolution.

The four laws of thermodynamics are:

Zeroth law of Thermodynamics: If two systems are in thermal equilibrium respectively with a third system, they must be in thermal equilibrium with each other.

First law of Thermodynamics: When energy passes, as work, as heat, or with matter, into or out from a system, its internal energy changes in accord with the law of conservation of energy.

Second law of Thermodynamics: In a natural thermodynamic process, the sum of the entropies of the interacting thermodynamic systems increases.

Third law of Thermodynamics: The entropy of a system approaches a constant value as the temperature approaches absolute zero.

Tornados actually demonstrate entropy by their expenditure of energy and eventual dissipation.

Tornadoes are order coming from disorder. Those who object to evolution like to claim that evolution violates the 2nd law of thermodynamics because it is order coming from disorder. If that were the case, then tornadoes would violate that law too. How do people who object to evolution who think it violates the 2nd law explain tornadoes?

They're probably ignorant of science in general, and both evolution and thermodynamics in particular.

Actually, tornadoes arise from certain ordered conditions of humidity, heat, and air flow. It is only the destruction they leave behind that is chaotic.

The second law of thermodynamics is about closed systems and even though the Universe is a closed system (As far as we know at least; we don't know for sure if wormholes toward other universe is possible or exists yet.), it's a very big one and it's even a expanding one, so there is more than enough space to let heat escape as photons, and as long as there is place for the increasing disorder and a energy source some order can form in a closed system. The energy for tornadoes and living things simply come from the sun.

Hmm...

If evolution is just a theory then so is gravity.

Those who object evolution are simply ignorant, either by choice or forced by their surroundings.

Evolution is as close to a fact as you can get within science, the 'theory' is simply about the underlying mechanism; the same with tornadoes.

Indeed, the second law of thermodynamics (which is completely irrelevant, as biology has several active processes, and the 2nd law is only about passive/spontaneous effects), applies only to closed systems, which earth is not.
