There are various types of maple and pine each with its own characteristics but the main difference in characteristics is that maple is hard and fine grained whereas pine is relatively soft and coarse grained. There is a list of various types of wood and their characteristics at `Properties and Uses of Woods' - http://www.inquirewithin.biz/Vol1/Woods/wood_properties.htm.
Maple is a hard wood (from a leafed tree) and pine is a soft wood (from a conifer). In this case both wood also have the described character (hard vs soft) not always the case.
Maple is the hardest of those woods. Oak is a hardwood also but not a dense as Maple. Pine is a softwood and thusly not near as strong or dense a Maple
a maple tree is vascular and a pine tree is nonvasclar
one is pine and one is teak....
The difference between coniferous and non-coniferous wood lies in cone-bearing wood coming from trees that produce needles such as pine and spruce species. Non-coniferous wood comes from trees that produce leaves such as maple, oak and apple.

There are many types. The main ones are Maple, Oak, Pine, and Locust.
Wood is named by the type of tree that it comes from. Maple, oak, pine, poplar, chesnut, walnut, cherry, etc.
...They're not the same. Maple trees are like regular trees and pine trees are Christmas trees. Maple trees produce syrup that you can eat. Where-as pine trees make sap but you can't eat that.
Maple would be the more durable choice as it is a harder wood than pine. This is important because the repeated insertion of knives into the block can cut grooves in the block where bacteria can fester leading to big problems in the future.
Pine is considered a softwood. As a general rule conifers are softwood and deciduas trees are hardwood. This is not always the case but there are not many exceptions.
