What are potholes? A. Long ridges of glacial till B. Circular depressions formed by stream erosion C. Crescent-shaped sand dunes D. Large, deep holes at the base of waterfalls Explanation: Potholes are rounded depressions in the bedrock of a riverbed, formed by the swirling action of water and sediment. 2 / 202. What are stalactites? A. Icicle-like formations hanging from cave ceilings B. Cone-shaped formations rising from cave floors C. Long ridges of glacial till D. Crescent-shaped sand dunes with points downwind Explanation: Stalactites are icicle-shaped mineral deposits hanging from the ceilings of caves, formed by the dripping of mineral-rich water. 3 / 203. What is a cirque? A. A deep, bowl-shaped basin carved by a glacier B. A crescent-shaped sand dune with points downwind C. A long ridge of glacial till D. A sharp, narrow ridge between two cirques Explanation: A cirque is a bowl-shaped, amphitheater-like depression carved out by the head of a glacier. 4 / 204. What are incised meanders? A. Meanders found in plains of alluvium B. Meanders formed by wind C. Meanders cut in hard rocks D. Meanders formed by glaciers Explanation: Incised meanders are meandering river channels that have cut deeply into bedrock, often found in areas where the land has been uplifted. 5 / 205. What is a gorge? A. A circular depression formed by wind erosion B. A deep valley with very steep to straight sides C. A flat plain formed by deposition D. A shallow valley with gentle slopes Explanation: A gorge is a narrow, deep valley with steep sides, often formed by river erosion in resistant rock formations. 6 / 206. What is a glacial valley? A. A V-shaped valley carved by a river B. A crescent-shaped sand dune with points downwind C. A long ridge of glacial till 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. 7 / 207. What is a peneplain? A. A type of desert B. A type of mountain C. An almost plain formed by stream erosion D. A type of glacier Explanation: A peneplain is a low-lying, nearly flat landform created by the erosional forces of running water over long periods. 8 / 208. What are stalagmites? A. Long ridges of glacial till B. Cone-shaped formations rising from cave floors C. Icicle-like formations hanging from cave ceilings D. Crescent-shaped sand dunes with points downwind Explanation: Stalagmites are upward-growing mineral deposits from the floor of caves, formed by the dripping of mineral-rich water. 9 / 209. What are river terraces? A. High, sharp-pointed peaks formed by glaciers B. Long ridges of sand and shingle parallel to the coast C. Surfaces marking old valley floor or floodplain levels 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. 10 / 2010. 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. 11 / 2011. 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. 12 / 2012. What are natural levees? A. Long ridges of sand and shingle parallel to the coast B. Low ridges of coarse deposits along river banks C. High, sharp-pointed peaks formed by glaciers D. Crescent-shaped sand dunes with points downwind Explanation: Natural levees are low, linear ridges of sediment that form along the banks of rivers, often during floods. 13 / 2013. What is the most important geomorphic agent in humid regions? A. Glaciers B. Groundwater C. Wind D. Running water 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. 14 / 2014. What is a meander? A. A waterfall B. A sharp bend in a river channel C. A straight channel pattern D. A loop-like channel pattern Explanation: A meander is a bend or curve in a river’s course, formed by the lateral erosion and deposition of sediment. 15 / 2015. What are sinkholes? A. Crescent-shaped sand dunes with points downwind B. Openings in the ground formed by the collapse of caves C. Circular depressions formed by wind erosion D. Long ridges of glacial till 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. 16 / 2016. What is an alluvial fan? A. A crescent-shaped sand dune with points downwind B. A flat plain formed by deposition at the mouth of a river C. A long ridge of glacial till D. A cone-shaped deposit formed where a stream enters a valley 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. 17 / 2017. What are caves? A. Long ridges of glacial till B. Crescent-shaped sand dunes with points downwind C. Underground chambers formed by wind erosion 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. 18 / 2018. What are point bars? A. Sediments deposited on the inside of meander bends B. High, sharp-pointed peaks formed by glaciers C. Crescent-shaped sand dunes with points downwind D. Long ridges of sand and shingle parallel to the coast Explanation: Point bars are crescent-shaped deposits of sediment found on the inside bends of meandering rivers. 19 / 2019. What is a horn? A. A deep, bowl-shaped basin carved by a glacier B. A long ridge of glacial till C. A crescent-shaped sand dune with points downwind 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. 20 / 2020. What is a delta? A. A flat plain formed by deposition at the mouth of a river B. A crescent-shaped sand dune with points downwind C. A cone-shaped deposit formed where a stream enters a valley D. A long ridge of glacial till 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.
