A. a gradual change in species over time
B. a change in the quartz
C. gold deposits in the veins of rocks
D. a change in the waters of the Bay of Fundy
B
One explanation for a relatively sudden extinction at the end of the Triassic may be that a large meteorite struck the earth at the time and is responsible for a 70- kilometer hole nearby. If geologists 15 and other researchers can find evidence, such as shocked quartz in the rock formations, that a meteorite did strike the earth, it would give more credence to the theory of rapid Triassic extinctions.
