Bacteria breaking down the materials cause heat. The compost should rise as high as 146-165 Degrees to fully kill all weed seeds and other organisms.
A compost heap is hot in the middle because this is where the microbes are starting to break down the material in the compost heap and as part of their process they generate heat.
To cause the material to heat up and aid decomposition.
Composting relies on natural processes that decompose organic materials. This includes certain chemical processes that are carried out by microorganisms which thrive under ideal conditions. They work most efficiently when the correct moisture level is present and they are given enough oxygen. Their activity creates the heat in a compost bin which can be warm enough to kill weed seeds and sterilize the material.
Well, there are more than two, strictly speaking, but oxygen and moisture content--although it should be understood that one can also have too much moisture.
If a substance can be broken down by biological action, it is considered "biodegradable". A good example of biodegradable material is anything you would put in a compost heap: egg shells, fruit remains, etc.
The internal temperature of a compost heap will fluctuate, due to the amount of carbon, nitrogen, and oxygen in the active pile. When all influences are in balance, the internal temperature will be between 90 degrees and 140 degrees Fahrenheit.

A compost heap is a pile of composting material that is in a pile on the ground. A compost pit is dug into the ground and the composting material is placed in it.
A compost heap has slits at the bottom so that oxygen can circulate through the dirt.
A compost heap is either anearobic or aerobic. Anaerobic bacteria are usually quite smelly, so to encourage aerobic bacteria, the compost heap supports are designed to allow air to get at as much as possible of the compost, by having gaps between them.
A compost pile is compost in a pile or heap. a compost pit is compost in a pit or hole in the ground.
A compost pit is composting materials put into a pit dug in the ground. A compost heap is when composting materials are placed in a heap on the surface of the ground.

You either turn them over so they compost or you let them grow and use them. It is better to remove potatoes from your compost heap turning them over will make no difference.
A compost heap is basically a big pile of leftover food scraps. As the material stacks up, the temperature inside the pile gets increasingly higher everyday. This is good because it means that microorganisms are at work. Once the food is fully decomposed by decomposers, the gardener has cheap and environmentally sound topsoil.
School gardens and science experiments are ways in which a school can use a compost heap. A compost heap functions as a repository for kitchen scraps and yard debris. It may lend itself therefore to community gardens and science class experiments.
Absolutely. ^_^ Rabbit droppings make GREAT compost!
