Balsa wood is the lightest.
strong lightweight wood is wood with small fibers, such as balsa
Because balsa wood is much lighter
Bamboo is a member of the grass family, so it isn't a hardwood in the sense of a maple or oak tree. However, because bamboo is very wood-like it can be cut into long, narrow planks which are laminated together into larger boards. Wood made this way can be used from construction-grade plywood, thicker furniture grade plywood, and flooring. Wood made from bamboo is hard, harder than oak, and so wood made from bamboo can be considered a hardwood in the way a maple or oak wood board is considered hardwood.
If the oak is down solid and no buckles, you can staple or glue most Bamboo over a suitable wood floor.. PLEASE check with the maker of teh Bamboo so you dont get blindsided.

i personally like wood or bamboo wainscoting and oak wainscoting is too great :)
There are several basic characteristics found in all wood, with several more present depending upon the type of wood being discussed. The basics of wood is that it is a fibrous, hard tissue harvested from the stems/trunks, roots and branches of trees and other woody plants. Most wood has a natural buoyancy, and most woods are able to be shaped with tools. For more specific attributes, it is best to focus on the wood type rather than wood in general, as the term "wood" applies to everything from oak and pine to balsa and bamboo.
Oak is strong, durable and not as easily dented. Having installed many bamboo, oak and maple floors, I find that maple generally shows wear the quickest, while oak generally takes the longest to show wear.
oak is a very hard wood
It depends on the wood. Most wood is lighter, some much lighter (e.g. balsa).However, some are heavier. English oak (quercus robur)and lignum vitae are classic examples.
