What is a large mass of ice that moves slowly over land?

• A. Desert pavement
• B. Glacier
• C. Karst topography
• D. Soil

Answer: (B)

The main idea here is recognizing a large, moving ice mass that shapes the landscape as it travels over land. A glacier forms when snow piles up year after year, compresses into dense ice, and then slowly flows under its own weight due to gravity. This flow can move the ice across valleys and mountains, gradually carving the terrain. The movement is slow, but sustained, and it happens on land, not on water. Desert pavement describes a rocky desert surface covered with pebbles, karst topography is a landscape shaped by the dissolution of soluble rocks like limestone, and soil is loose mineral and organic material on the ground. None of these are massive bodies of ice that move across land, which is why a glacier is the correct choice.
