Document Summary
Low frequency soundwaves that are too low for humans to hear. Deep base tones reflecting huge amounts of energy. Deeper base tones are below the level of human hearing. Clues occurred was a low total frequency that can travel a long distance for a long time. Low frequency noise propagates longer than high frequency noise. The low frequency sound travelled and circled the world a few times from the blast. The stations with sensitive sensors that detected this were larger waves than ever seen before: describe the composition of a stony iron meteorite. The composition of a stony iron meteorite is a mixture of rock and metal. There is so much metal in them that they weight more than other meteorites and extremely dense, so the damage is huge with a large size and cosmic speed. They can survive the searing of the earth"s atmosphere and leave fragments on the.
