Document Summary
Chapter 8: moon: what is tidal coupling, due to earth gravitational influence on the moon, it has forced the moon into exactly the same rotational period and orbital period as the earth. Because it has a low escape velocity (the speed which any object needs to escape gravity) and the gas atoms near its surface escape easily into space. Thus, you cant make a new one without hitting an old one. The marias on the other hand don"t have as many as the highlands. Thus, we can conclude that the highlands are old region where we see craters from early in history when the. Whats a rilles: a maria is a darkened area on the nearside of the moon. The dark material filling the maria is solidified basalt lava. If the same size meteorite were to hit the earth and moon, which would form the bigger crater: the meteorite hitting the moon.
