What is the process of cross cutting wood and how is it different from ripping wood?

Cross cutting wood involves cutting across the grain of the wood, while ripping wood involves cutting along the grain. Cross cutting is typically done to shorten the length of the wood, while ripping is done to reduce the width of the wood. The tools and techniques used for each process are different, with cross cutting often requiring a saw with finer teeth for a smoother cut, and ripping requiring a saw with coarser teeth for faster cutting along the grain.
