Question
You hear that studies have found a evidence for a volcanic eruption of nearly pure nickel-iron, reportedly from the Earth's outer core. This story is most likely to be accurate if (circle best answer): it is aired on Channel 30 with an interview of a Fresno State geology professor; It is published in the Collegian with quotations from a U.S. Geological Survey geologist; It was posted on the website of a USC geology professor who is an expert in the studies of the core; it was published in a peer-reviewed scientific journal; There is a feature on Wikipedia about this finding. More people in the world are threatened or harmed by natural disasters today than 100 years ago because (circle best answer) plate tectonics are more active today than 50 years ago; of the dependence of people on cell phones; of improvement in construction technology have made people overly complacent and careless; human activities, including pollution are triggering more earthquakes and volcanic eruptions; of satellite communications technology; of more rapid and efficient transportation systems, of global population increase When you hear about moving plates on the Earth ("plate tectonics") one is referring to plates composed of (circle one): various galaxies that are plate- like in 3 dimensional shape; oceanic crust only; clouds; the inner core; the lithosphere; dry crust that forms on some soil; the biosphere only; the lower mantle; the outer core; continental crust only.
Explanation / Answer
2 Option D: Any scientific finding can are needed to be published in scientific journal so that any body can get access in order to get the thing verified without which it's of no use, in science world. As I can too can give any theory but it'll be of no use until it's being verified and published in scientific journal.
3 Option D: 100 years back life was easy and we were not so much dependent on the natural resources and we were not exploiting our natural resources, but now we are not only exploiting but the rate is at greatest peak and the tackiness that we are using is disturbing the cohesion of the inside rock this is causing or triggering more disaster.
4 Option E: Plate tectonics refer to the division of the earth lithosphere into major 7 to 8 plates based upon our choice of classification.
