When it strikes the surface of the earth, its velocity and ke go to zero in an instant, but the law of conservation of energy holds that the energy is not simply lost it is transferred to the surroundings as heat, light, and work, sending out shock waves and excavating a crater far larger than the meteorite itself.
Study site: meteor crater, arizona is located in semi-arid north-central arizona and is estimated to be 49,000 to 50,000 years old, making it one of the most. The moon’s surface is riddled with craters ranging in size and structural complexity, and billions of years ago before life emerged, the earth looked the same way “the bottom line is, everything that happened on the moon happened on the earth,” said david kring, crater expert and team leader .
