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