The photograph shows fossilized ammonoids in a rock outcrop.
The presence of these fossils in the outcrop indicates that in the past, this region was most likely covered by
desert sand
ocean water
glacial ice
molten rock
The cross section represents rock units within Earth’s crust. Sedimentary rock layers are labeled 1 through 6.
The age of the igneous rock is
older than rock layers 1 and 2
the same age as rock layer 3
older than rock layer 3
younger than rock layers 4, 5, and 6
The photograph shows boulders and other sediments that slid down a hillside.
This rock slide is most likely an example of
mass movement due to prolonged periods of heavy traffic
mass movement following prolonged periods of heavy rain
abrasion by prolonged exposure to moving ice
abrasion following prolonged exposure to wind action
