Question
In the photograph of Stephen's Isle below, what change in the environment could account for this sequence of rocks?
a. the sequence represents a transgression
b. the sequence represents an angular unconformity
c. the sequence represents an unconformity
d. the sequence represents a regression
What is the sequence of events that occurred to deposit the rocks in the photograph of the Inner Granite Gorge (below) and what is the nature of the contact below the sandstone?
a. The metamorphic rocks formed first and were then intruded by the granitic dikes. The metamorphic and granitic rocks were then uplifted and eroded, forming an unconformity. Finally, the sandstone was deposited
b. The sandstone was formed and then the bottom was eroded to form an unconformity. The metamorphic rocks and granitic dikes were pressed into the sides of the sandstone.
c. The granitic dikes formed first and then were inundated by the metamorphic rocks. The granitic dikes and metamorphic rocks were uplifted and eroded. Finally, the sandstone was deposited.
d. The sandstone was formed first and then the granitic dikes intruded to the bottom of the sandstone, the metamorphic rocks were then formed and created a transgression.

1.
Answer: a. the sequence represents a transgression
Explanation: From the figure, the sequence represents a transgression.
2.
Answer: a
Explanation: From the figure, the metamorphic rocks formed first and were then intruded by the granitic dikes. The metamorphic and granitic rocks were then uplifted and eroded, forming an unconformity. Finally, the sandstone was deposited.
