Answer:
C. Continental glaciers are much larger and thicker.
Step-by-step explanation:
One main difference between continental glaciers and valley glaciers is their size and thickness. Continental glaciers are vast ice sheets that cover large areas of land and can be several kilometers thick, while valley glaciers are smaller and form in mountain valleys and can be a few hundred meters thick. This difference in size and thickness also affects the way they move and erode the landscape. Continental glaciers tend to flow slowly in all directions, while valley glaciers move faster down a steep slope and cause more erosion in the valleys they occupy.
