16. which of the following families of the trilobites would be the most effective index fossil?
ans. (a) phacopina
17. during the time of the formation of the Franciscan Complex, the wison cycle stage of california was
ans.(a) subduction zone
18. true or false. volcanoes are often present during the continental rift part of the early rifting stage of the wilson cycle
ans. False
because at the continental rift plates moves away from each other and lava comes ffrom the interior of the earth and makes mid oceanic ridge whether volcanos are found at the subduction zone at the surface of the lless dense plate.
19. a gas is considered a "greenhouse gas " when it.
ans . greenhouse gases are capable to store the solar radiation with in and prevent the solar raiation to go into the space. so the right option is (C) prevents some heat radiation from escaping the atmosphere into space
20. which of the following best descibes the facies that would be formed in a delta
ans. (a) limestone and fossil
21. which of the following could be considered a hypothesis.
ans . hypothesis word refer the supposition or assumption of any evevnt without any full proof evidence. here A and B are the hypothesis and C is the analytical work, which concluded by the research work . so the option (e) is right
(e) A and B only
22. Recall that on our trip to Patrick's point we observed an outcrop with Franciscan Complex rocks at the base, overlain by conglomerate with large boulders , overlain by granule sized sediment , overlain by fine sand , silt and clay. this form an overall
ans. it is regression.
all material is in organized manned by our weights, which is possible in regression process when a submerged land come out on the surface
23. many jurrasic rocks in the southwest have cross bed sets are several meters high . these formed because during the jurrasic
ans. (a) there was an interior seaway that left behind marine sedimentary rocks.
24. which modern day location is an example of a closing remnant ocean basin?
ans (D) the mediterranean sea
this is the example of the continent continent collision and then upliftment
