There are many trees we use like the deciduous tree, poplar, willow, elm, beech, oak and many more. There split into 2 different kinds of wood. Hardwood and softwood. But that doesn’t mean the wood is hard or soft.
The form of a tree can be different in many ways. They can be small with the roots in the ground, or the exact opposite. A very big tree with the roots in and above the ground so you can walk or even drive with your car underneath it.
