how are they identified?
Non-explosive volcanic craters can usually be distinguished by their irregular shape and the association of volcanic flows and other volcanic materials.

where was the first moon landing launched from Kennedy Space Center what was the name of the mission? Apollo 11 which operations were performed on the surface of the moon? They jettisoned "Eagle" before they performed the maneuvers that propelled "Columbia" out of the last of its 30 lunar orbits onto a trajectory back to Earth. what is the surface geology of the said astronomical body like? Its atmosphere and oceans were formed by volcanic activity and outgassing. how strong is its magnetic field compared to earth? It has an external magnetic field of generally less than 0.2 nanoteslas, or less than one hundred thousandth that of Earth. and gravitational field? UNANSWERABLE does it have any impact craters? Yes, which formed when asteroids and comets collided with the lunar surface. on which other planets are such craters found? Mercury, Callisto, Ganymede are there such craters on earth? Yes where are they located? UNANSWERABLE

Impact crater [SEP] Identifying impact craters
Non-explosive volcanic craters can usually be distinguished from impact craters by their irregular shape and the association of volcanic flows and other volcanic materials. Impact craters produce melted rocks as well, but usually in smaller volumes with different characteristics. The distinctive mark of an impact crater is the presence of rock that has undergone shock-metamorphic effects, such as shatter cones, melted rocks, and crystal deformations. The problem is that these materials tend to be deeply buried, at least for simple craters. They tend to be revealed in the uplifted center of a complex crater, however. Impacts produce distinctive shock-metamorphic effects that allow impact sites to be distinctively identified.
