Given an estimate of the mass and speed of the asteroid, the effects can be modeled (see Activities 2–4 in this chapter). For instance, if we assume the asteroid was 10 km in diameter (based on the size of the crater beneath the Yucatán Peninsula), and was traveling about 30 km per second (about the average speed of meteorites), and had the density of an average asteroid, then the energy released by its impact would be equal to about 10 billion 15-kiloton (about the size of the atomic bomb dropped on Hiroshima) atomic bombs.
They have a single large bone in the upper arm (humerus) or upper leg (femur), two long bones in the lower arm (radius and ulna) or lower leg (tibia and fibula), small bones in the wrist (carpals) and ankle (tarsals), bones in the palm of the hand (metacarpals) and foot (metatarsals), and fingers and toes (digits). 23 Human (left) and crocodile (right) leg.
