<human>:  What is the difference between hardwood and softwood?
<bot>: Hardwood is typically composed of denser grain and is stronger than softwood, making it resistant to temperature and moisture changes. Hardwood is also more difficult and expensive to work with than softwood, and it takes longer to cure, so it's usually used for furniture and flooring because of its durability. Softwood, on the other hand, is easier and more affordable to work with, so it's often used for construction and structural framing.
