What are sinkholes? A. Long ridges of glacial till B. Circular depressions formed by wind erosion C. Crescent-shaped sand dunes with points downwind D. Openings in the ground formed by the collapse of caves Explanation: Sinkholes are depressions or holes in the ground caused by the collapse of the surface layer, often in areas underlain by soluble rock like limestone. 2 / 202. What is a glacial valley? A. A crescent-shaped sand dune with points downwind B. A long ridge of glacial till C. A V-shaped valley carved by a river D. A U-shaped valley carved by a glacier Explanation: A glacial valley, also known as a glacial trough, is a long, U-shaped valley carved out by the erosive forces of a glacier. 3 / 203. What is a gorge? A. A flat plain formed by deposition B. A deep valley with very steep to straight sides C. A shallow valley with gentle slopes D. A circular depression formed by wind erosion Explanation: A gorge is a narrow, deep valley with steep sides, often formed by river erosion in resistant rock formations. 4 / 204. What is a cirque? A. A sharp, narrow ridge between two cirques B. A long ridge of glacial till C. A crescent-shaped sand dune with points downwind D. A deep, bowl-shaped basin carved by a glacier Explanation: A cirque is a bowl-shaped, amphitheater-like depression carved out by the head of a glacier. 5 / 205. What are incised meanders? A. Meanders formed by glaciers B. Meanders formed by wind C. Meanders cut in hard rocks D. Meanders found in plains of alluvium Explanation: Incised meanders are meandering river channels that have cut deeply into bedrock, often found in areas where the land has been uplifted. 6 / 206. What is a meander? A. A loop-like channel pattern B. A waterfall C. A sharp bend in a river channel D. A straight channel pattern Explanation: A meander is a bend or curve in a river’s course, formed by the lateral erosion and deposition of sediment. 7 / 207. What are point bars? A. Crescent-shaped sand dunes with points downwind B. Sediments deposited on the inside of meander bends C. Long ridges of sand and shingle parallel to the coast D. High, sharp-pointed peaks formed by glaciers Explanation: Point bars are crescent-shaped deposits of sediment found on the inside bends of meandering rivers. 8 / 208. What is a horn? A. A long ridge of glacial till B. A crescent-shaped sand dune with points downwind C. A deep, bowl-shaped basin carved by a glacier D. A sharp, pointed peak formed by the intersection of three or more cirques Explanation: A horn is a sharp, pyramidal peak formed by the headward erosion of multiple glaciers converging on a central point. 9 / 209. What is an alluvial fan? A. A cone-shaped deposit formed where a stream enters a valley B. A long ridge of glacial till C. A flat plain formed by deposition at the mouth of a river D. A crescent-shaped sand dune with points downwind Explanation: An alluvial fan is a fan-shaped deposit of sediment formed where a fast-flowing stream emerges from a mountainous area onto a flatter plain. 10 / 2010. What are stalactites? A. Long ridges of glacial till B. Icicle-like formations hanging from cave ceilings C. Crescent-shaped sand dunes with points downwind D. Cone-shaped formations rising from cave floors Explanation: Stalactites are icicle-shaped mineral deposits hanging from the ceilings of caves, formed by the dripping of mineral-rich water. 11 / 2011. What are river terraces? A. High, sharp-pointed peaks formed by glaciers B. Surfaces marking old valley floor or floodplain levels C. Long ridges of sand and shingle parallel to the coast D. Crescent-shaped sand dunes with points downwind Explanation: River terraces are step-like landforms along river valleys, representing former floodplains or valley floors that have been abandoned as the river cut down to a lower level. 12 / 2012. What are caves? A. Underground chambers formed by wind erosion B. Long ridges of glacial till C. Crescent-shaped sand dunes with points downwind D. Underground chambers formed by the dissolution of limestone Explanation: Caves are natural underground voids or chambers, often formed by the dissolving action of acidic groundwater on soluble rock like limestone. 13 / 2013. What are potholes? A. Large, deep holes at the base of waterfalls B. Crescent-shaped sand dunes C. Long ridges of glacial till D. Circular depressions formed by stream erosion Explanation: Potholes are rounded depressions in the bedrock of a riverbed, formed by the swirling action of water and sediment. 14 / 2014. What are stalagmites? A. Icicle-like formations hanging from cave ceilings B. Crescent-shaped sand dunes with points downwind C. Long ridges of glacial till D. Cone-shaped formations rising from cave floors Explanation: Stalagmites are upward-growing mineral deposits from the floor of caves, formed by the dripping of mineral-rich water. 15 / 2015. What is the most important geomorphic agent in humid regions? A. Groundwater B. Running water C. Wind D. Glaciers Explanation: Running water is the most important geomorphic agent in humid regions due to its ability to erode, transport, and deposit vast amounts of material, shaping the landscape over time. 16 / 2016. What is a glacier? A. A crescent-shaped sand dune with points downwind B. A large mass of ice floating in the ocean C. A large mass of ice formed by compacted snow D. A long ridge of glacial till Explanation: A glacier is a persistent body of dense ice that is constantly moving under its own weight, formed by the accumulation and compaction of snow over time. 17 / 2017. What is a delta? A. A long ridge of glacial till B. A crescent-shaped sand dune with points downwind C. A cone-shaped deposit formed where a stream enters a valley D. A flat plain formed by deposition at the mouth of a river Explanation: A delta is a landform created at the mouth of a river where it enters a slower-moving or standing body of water, like a lake or ocean. 18 / 2018. What is a peneplain? A. An almost plain formed by stream erosion B. A type of glacier C. A type of desert D. A type of mountain Explanation: A peneplain is a low-lying, nearly flat landform created by the erosional forces of running water over long periods. 19 / 2019. What is a Karst topography? A. A landscape formed by volcanic activity B. A landscape formed by glacial erosion C. A landscape formed by groundwater erosion in limestone D. A landscape formed by wind erosion Explanation: Karst topography is a distinctive landscape characterized by sinkholes, caves, and underground drainage systems, formed by the dissolution of soluble rocks like limestone. 20 / 2020. What are natural levees? A. Crescent-shaped sand dunes with points downwind B. High, sharp-pointed peaks formed by glaciers C. Low ridges of coarse deposits along river banks D. Long ridges of sand and shingle parallel to the coast Explanation: Natural levees are low, linear ridges of sediment that form along the banks of rivers, often during floods.
