how is the Alvarez hypothesis relate to geology astronomy meteorology and oceanography?

Answer 1

are you referring to the alvarez team of pysicists from uc berkeley? if so, then he theorized and was later proven correct that a celestial object..meteor..slammed into hte earth some 65 million years ago thus sending billions of tons of particles into the atmosphere blocking out the sun...the earth cooled and was held in darkness for some time. the food chain was crushed and the dinosaurs died out. 20 year later the meoteor impact crater was located in the yucatan pen insula in mexico. iridium was the key ingrediant as it is common in meteors but uncomon in earths crust. iridim is found in abundance in the layer of rockdated 65 million years ago. iridium from space... for a more clear explanation check out info on dinasaur extinction

The Alvarez layer can be seen in ocean sediment cores, and has been dated to 65 million years old. It is high in the element, iridium, which is not native to this planet. It is thought that this iridium came to earth when an asteroid crashed into Earth, landing in the Yucatan Peninsula of Mexico. The resulting explosion caused a huge tsunami, raging firestorms, and a "nuclear winter" which lasted many years. Consequently over 90% of all living things on earth at the time perished due to lack of sunlight for photosythesis.

because of the fact the others have reported, they are maximum magnificent.. additionally, in each and every occupation, there are additionally sub-categories of scientists too.. there are various categories of "Oceanographers".. anybody that learn the "ocean" or issues with, approximately or interior the sea are definitely oceanographers too.. nonetheless they opt to pass by potential of their expert titles as such.. Making "Oceanographer" greater of a time-honored term (nonetheless the identify does additionally keep on with to an definitely expert who does in actuality "be taught the oceans".. And scientists from different fields could additionally in good shape into the comparable field in the event that they keep on with their occupation directly to the given field (Oceanography).. An Icthyologist is a scientist who learn fish.. yet in time-honored words, they are seen a consultant expert interior the oceanographic field or occupation.. it is the comparable with Geology.. In Geology, there are sub categories which include a Gemologist or a Minerologist.. And yet, a Geologist or Minerologist or maybe a Meteorologist, is additionally seen "Oceanographers" in the event that they keep on with their awareness to ocean learn, to which many specialists in actuality do.. the comparable is going with different scientific specialists besides.. desire this facilitates..
