Wood is a natural material that comes from the stems and branches of trees and shrubs. It is a versatile material that has been used by humans for thousands of years for various purposes, including building, fuel, and crafting.
Types of Wood
There are two main types of wood: hardwood and softwood. Hardwood comes from deciduous trees, which are trees that shed their leaves annually, such as oak, maple, and cherry. Softwood comes from coniferous trees, which are trees that have needles and cones, such as pine, cedar, and spruce.
