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. 2 / 202. What is a peneplain? A. A type of mountain B. A type of glacier 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. 3 / 203. What is a horn? A. A crescent-shaped sand dune with points downwind B. A deep, bowl-shaped basin carved by a glacier C. A sharp, pointed peak formed by the intersection of three or more cirques D. A long ridge of glacial till Explanation: A horn is a sharp, pyramidal peak formed by the headward erosion of multiple glaciers converging on a central point. 4 / 204. What are potholes? A. Circular depressions formed by stream erosion B. Long ridges of glacial till 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. 5 / 205. What is a glacial valley? A. A crescent-shaped sand dune with points downwind B. A U-shaped valley carved by a glacier C. A V-shaped valley carved by a river 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. 6 / 206. What is a meander? A. A loop-like channel pattern B. A straight channel pattern C. A waterfall D. A sharp bend in a river channel 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 is an alluvial fan? A. A flat plain formed by deposition at the mouth of a river B. A long ridge of glacial till C. A crescent-shaped sand dune with points downwind 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. 8 / 208. What is a cirque? A. A long ridge of glacial till B. A sharp, narrow ridge between two cirques 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. 9 / 209. What are stalagmites? 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: Stalagmites are upward-growing mineral deposits from the floor of caves, formed by the dripping of mineral-rich water. 10 / 2010. What are caves? A. Underground chambers formed by the dissolution of limestone B. Crescent-shaped sand dunes with points downwind C. Underground chambers formed by wind erosion D. Long ridges of glacial till Explanation: Caves are natural underground voids or chambers, often formed by the dissolving action of acidic groundwater on soluble rock like limestone. 11 / 2011. 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. 12 / 2012. What are river terraces? A. Surfaces marking old valley floor or floodplain levels B. Crescent-shaped sand dunes with points downwind C. High, sharp-pointed peaks formed by glaciers 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. 13 / 2013. What are incised meanders? A. Meanders formed by wind B. Meanders found in plains of alluvium C. Meanders formed by glaciers 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. 14 / 2014. What is the most important geomorphic agent in humid regions? A. Running water B. Groundwater C. Glaciers D. Wind 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. 15 / 2015. What are point bars? A. Long ridges of sand and shingle parallel to the coast B. Crescent-shaped sand dunes with points downwind C. Sediments deposited on the inside of meander bends 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. 16 / 2016. 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. 17 / 2017. What is a Karst topography? A. A landscape formed by wind erosion B. A landscape formed by glacial erosion C. A landscape formed by volcanic activity D. A landscape formed by groundwater erosion in limestone Explanation: Karst topography is a distinctive landscape characterized by sinkholes, caves, and underground drainage systems, formed by the dissolution of soluble rocks like limestone. 18 / 2018. What are sinkholes? A. Long ridges of glacial till B. Circular depressions formed by wind erosion C. Openings in the ground formed by the collapse of caves D. Crescent-shaped sand dunes with points downwind 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. 19 / 2019. 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 long ridge of glacial till D. A large mass of ice formed by compacted snow 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. 20 / 2020. What are natural levees? A. Crescent-shaped sand dunes with points downwind B. Long ridges of sand and shingle parallel to the coast 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.
