The crater is not large enough to cause any permanent damage such as flooding, extinction for weather patterns. Since it is falling from the sky at such a great velocity it will of course leave a little "dent" in earths surface. This is short term because overtime the crater will fill in an become flat ground.
Dimples are usually found on both cheeks. A rarer form is the single dimple, which occurs on one side of the face only. Anatomically, dimples may be caused by variations in the structure of the facial muscle known as zygomaticus major.
