Indeed it is. Hey -- shoveling represents an intense workout even for healthy college-aged students! A study performed by researchers at North Dakota State University determined that, based on heart rate, shoveling was a moderately intense activity for college-aged subjects most of the time but was vigorous activity during about one-third of their shoveling time of 14 minutes.

Roughly ten. It varies a little with the type of snow.
Bird tracks in snow are not fossils, because snow melts and gets covered up by more snow, and so the bird that made them is probably still alive. (If it died shortly after and the tracks were still there, then they might be considered a trace fossil. ;))
A warm front typically brings light snowfall that is less intense compared to a cold front, resulting in wet and heavy snow. This type of snow is often associated with warmer temperatures and can lead to slushy conditions.
Activity series are useful for single displacement reactions.

Anaerobic and aerobic describes that type of physical activity.
Soccer is an aerobic physical activity in which a person has to move his large muscles. In the case of soccer, the player has to use the large muscles in his legs. This type of physical activity also makes the heart beat faster and the lungs work harder.
An acceptable job for high school students would be waitressing or maybe babysitting. Mowing lawns, shoveling snow and extra chores are also good.
Anaerobic and aerobic describes that type of physical activity.
A type of activity that uses (mainly) your lungs and respiration, eg. long distance running, swimming.
