Wood.

Lumbar - Freshly felled tree trunk

Wood - The material gained from Lumbar

Timber - Processed wood (material)

Hard woods-Comes from deciduous trees-Slow growing-More expensive than soft woods, due to time taken to grow.
Soft woods-Comes from coniferous trees-Relatively fast growing-Relatively cheap as they take less time to grow - Better land use.

You can tell the age of a tree by the number of 'age rings' (annual rings) in its trunk.Light rings signify summersDark rings signify autumn/winters - when a tree collects resin to just underneath the bark to protect the tree from the colder temperatures
