7. The diagram below represents a cross section of a pOliion of the Earth's crust.
Ocean
Oceanic crust (basalt)

9. The diagram below represents a geologic cross section of a portion of Earth's crust.
Continental crust (granite)
I
\~
( Not drawn to scaie )
Folding and erosion occurred after the fOlmation of the (1) Gayle shale (2) Freeport sandstone (3) Erie coal, but before formation of Freeport sa.lldstone (4) Dunbar limestone, but before formation or Erie coal
¥lmch statement about the Earth's crust is best supported by the diagram? (1) The oceanic crust is thicker than the mantle. (2) The continental crust is thicker than the oceanic crust. (3) The continental crust is composed primarily of sedimentary rock. (4) The crust is composed of denser rock than the mantle is.
10. Which geologic event occurred most recently in New York State? (1) A continental glacier covered most of the State. (2) The entire State was uplifted fi.om below sea leveL (3) The Palisades Sill intruded. (4) The Taconic Mountains formed.
8. The diagram below represents cross sections of three rock outcrops approximately 100 kilometers apart. \\That would be the best method or correlating the rock layers of each outcrop?
