sand) because the sand has formed from rocks that weathered away more easily. We consider the dolerite dike more resistant to weathering, because it resists weathering. Differential weathering in an outcropping of rock can produce dramatic landscapes. If a rock weathers easily, it will break down easily making gentle slopes. If a rock resists weathering, it will make steep cliffs. Visit Monument Valley in Arizona. Notice that the towers of rock are more resistant to weathering, while the gentle sided slopes at the bottom of the towers weather more easily. (7 points) Now visit LaSalle Canyon at Starved Rock State Park in Illinois. The evidence of differential erosion is less obvious. Describe where in the LaSalle Canyon you see resistant or easily weathered layers. What evidence can you observe of differential weathering?
