Question 1 6.76 pts The diagram I represents a map view of a stream with reference points A through F within the stream bed. Diagram II represents a geologic cross section of the area over which the stream flows. Assume that the volume of water in the stream is constant. If overturning of rock layers has not occurred, at which point is the stream flowing over the youngest bedrock? \begin{tabular}{l|l|l|l|l|l} O & 0 & 0 & 0 & 0 & 0 \\ 7 & m & 0 & & & > \end{tabular} The diagram represents a cross section on the Earth's crust showing several rock layers containing marine fossils. Overturning of rock layers has not occurred. The diagram is not to scale. Use this to answer questions 2 and 3 . (Note: Contact metamorphism occurs when hot magma comes into contact with cool rock causing the rock to change form due to the heat from the magma). Which best describes the order of events for the formation of this section of the Earth's crust? deposition of rock layers 1 , 2 , 3 , 4 , 5 , and 6 ; intrusion of basalt deposition of rock layers 1, 2, 3, 4, and 5; intrusion of basalt; deposition of rock layer 6 deposition of rock layers 1 , 2 , 3 ; intrusion of basalt; deposition of rock layers 4,5 , and 6 What best describes the absence of the Echinoderms fossil in layer 4 ? layer 4 was deposited very quickly the Echinoderms were extinct after layer 3 was formed the igneous intrusion burned off all trace of the Echinoderms fossil.
