Say you wake up in Vail and itâs snowing hard. If the temperature at the base is 20Â°F and the summit is about 3,000 feet higher, then you could estimate the temperature at the top would be about 10Â°F (3,000 feet elevation change at 3.3Â°F per 1,000 feet equals about 10Â°F temperature decrease).
Crepitus is the medical term for cracking or popping sound in a joint such as the knee. Learn about crepitus pain symptoms and treatment in this article.
The sound can be created when two rough surfaces in an organism's body come into contactâfor example, in osteoarthritis or rheumatoid arthritis when the cartilage around joints erodes and the surfaces in the joint grind against one another, or when the fractured surfaces of two broken bones rub together. Crepitus is a common sign of bone fracture.
