At the elbow joint, two bones meet. There is a cavity between the bones and cartilage covers the ends of each bone for protection. What type of joint is it?

The elbow is a synovial joint. Synovial joints have a cavity between the bones, and cartilage covers the bone ends to reduce friction and protect them. A fixed joint does not allow movement, while a cartilaginous joint is joined by cartilage without a synovial cavity.
