When your body starts exercising it undergoes various physiological changes in order to try and maintain homeostasis (keeping everything inside the body constant). During exercise your muscles require more oxygen so that they can carry out respiration and synthesis ATP (energy). This requires the heart to beat harder and faster (according to Starling's Law). A secondary effect is the release of adrenaline. This causes local vasodilation (blood vessels get wider), in effect reducing the total peripheral resistance to blood flow (think about water flowing through narrow and wide tubes - its faster in the wide ones).

The difference you are asking about could be due to many factors - the proximity of the dilated blood vessels to the skin; the number of blood vessles; and the extent to which they dilate.

What is the difference between aerobic exercise and anaerobic exercise?

Aerobic exercise is exercise with oxygen, in other words, exercise that gets you breathing hard by utilizing your cardiovascular system. Running, jogging, swimming, and walking are examples of aerobic exercise. Anaerobic exercise is exercise without oxygen, in other words, exercise that does not get you breathing hard. Doing a single squat or bench press are examples of anaerobic exercise. Actually, every exercise is at least slightly aerobic or slightly anaerobic. Also, many anaerobic exercises can be made aerobic simply by doing more of them, for example, doing 50 bench presses or squats without pausing.
