craters are some of the most dramatic features that can be seen on the Moon. They are formed when meteorites, asteroids, and comets struck its surface at speeds of
10-20 kilometers per second, craters record the Moon’s 4.5 billion year history.
have blocky rims like this crater from the highlands of the lunar far side.
tongues of lava-like material also extend downslope from the crater rim, its apperance is long, jumbled and gradually downward sloping. These
flows may consist of fragmented rock debris, but it is because of that
they are impact-produced melts ejected at low velocities during the late stages
of the formation of the impact crater. Andh hence it is formed.
