What is glacial till? A. A crescent-shaped sand dune with points downwind B. A long ridge of glacial till C. Sorted and stratified sediment deposited by glacial meltwater D. Unsorted and unstratified debris deposited by a glacier Explanation: Glacial till is unsorted glacial sediment, comprising a wide range of particle sizes, from clay to boulders, deposited directly by the ice. 2 / 202.

A deep glacial trough flooded by seawater D. A crescent-shaped sand dune with points downwind Explanation: An off-shore bar is a submerged or partly exposed ridge of sand and gravel, formed in the offshore zone parallel to the coast.3 / 203. What is a wave-built terrace? A. A crescent-shaped sand dune with points downwind B. A deep glacial trough flooded by seawater C. A flat or gently sloping platform in front of a sea cliff D. A depositional feature formed by the accumulation of sediment in the offshore zone Explanation: A wave-built terrace is a submerged, flat or gently sloping platform formed by the deposition of sediment eroded from the coast. 4 / 204. What are sand dunes? A. Mounds or ridges of sand formed by wind deposition B. Crescent-shaped sand dunes with points downwind C. Long ridges of sand and shingle parallel to the coast D. Deep glacial troughs flooded by seawater Explanation: Sand dunes are mounds or ridges of sand formed by the deposition of wind-blown sand, often found in deserts and coastal areas. 5 / 205. What is a wave-cut platform? A. A flat or gently sloping platform in front of a sea cliff B. A long ridge of sand and shingle parallel to the coast C. A crescent-shaped sand dune with points downwind D. A deep glacial trough flooded by seawater Explanation: A wave-cut platform is a flat or gently sloping surface cut by wave erosion at the base of a sea cliff. 6 / 206. What is the primary agent of change along coasts? A. Running water B. Waves C. Wind D. Glaciers Explanation: Waves are the primary agent of change along coasts, as they constantly erode, transport, and deposit sediment, shaping the shoreline over time. 7 / 207. What are drumlins? A. Deep, bowl-shaped basins carved by glaciers B. Crescent-shaped sand dunes with points downwind C. Long ridges of glacial till D. Oval-shaped hills of glacial till Explanation: Drumlins are elongated, teardrop-shaped hills composed of glacial till, formed beneath a moving glacier. 8 / 208. What are eskers? A. Long ridges of glacial till B. Sorted and stratified sediment deposited by glacial meltwater C. Sinuous ridges of sand and gravel deposited by subglacial streams D. Crescent-shaped sand dunes with points downwind Explanation: Eskers are long, winding ridges of stratified sand and gravel, formed by the deposition of sediment within meltwater channels beneath a glacier. 9 / 209. What are sand dunes? A. Deep glacial troughs flooded by seawater B. Mounds or ridges of sand formed by wind deposition C. Long ridges of sand and shingle parallel to the coast D. Crescent-shaped sand dunes with points downwind Explanation: Sand dunes are mounds or ridges of sand formed by the deposition of wind-blown sand, often found in deserts and coastal areas. 10 / 2010. What is a spit? A. A deep glacial trough flooded by seawater B. A crescent-shaped sand dune with points downwind C. A barrier bar that is connected to the mainland at one end D. A long ridge of sand and shingle formed in the sea parallel to the coast Explanation: A spit is a narrow, elongated coastal landform, typically composed of sand or shingle, that extends from the mainland into a body of water. 11 / 2011. What is a pediment? A. A long ridge of glacial till B. A gently inclined rocky floor at the foot of a mountain C. A flat plain formed by deposition at the mouth of a river D. A crescent-shaped sand dune with points downwind Explanation: A pediment is a gently sloping, erosional surface of bedrock found at the base of a mountain or other high ground, often covered by a thin veneer of sediment. 12 / 2012. What are the two dominant agents of erosion in hot deserts? A. Running water and glaciers B. Wind and running water C. Coastal processes and wind D. Glaciers and wind Explanation: Wind and running water are the two dominant agents of erosion in hot deserts, shaping the landscape through deflation, abrasion, and transportation of sediment. 13 / 2013. What is a lagoon? A. A deep glacial trough flooded by seawater B. A long ridge of glacial till C. A shallow body of water separated from the sea by a barrier bar or spit D. A crescent-shaped sand dune with points downwind Explanation: A lagoon is a shallow body of water separated from the open sea by a barrier bar, spit, or other coastal landform. 14 / 2014. What are the two types of coasts considered in the context of coastal landform evolution? A. Coral coasts and mangrove coasts B. Sandy coasts and rocky coasts C. High, rocky coasts and low, sedimentary coasts D. Glacial coasts and volcanic coasts Explanation: The two types of coasts considered in the context of coastal landform evolution are high, rocky coasts (submerged coasts) and low, sedimentary coasts (emerged coasts). 15 / 2015. What is a playa? A. A gently inclined rocky floor at the foot of a mountain B. A shallow, temporary lake in a desert basin C. A flat plain formed by deposition at the mouth of a river D. A crescent-shaped sand dune with points downwind Explanation: A playa is a dry, flat lake bed found in desert basins, often covered with salt deposits due to evaporation. 16 / 2016. What is a beach? A. A deep glacial trough flooded by seawater B. A crescent-shaped sand dune with points downwind C. A long ridge of sand and shingle parallel to the coast D. A depositional landform made up of sand-sized materials Explanation: A beach is a narrow strip of land along the shoreline, typically composed of sand, gravel, or pebbles, deposited by waves and currents. 17 / 2017. What is a fjord? A. A sharp, narrow ridge between two cirques B. A deep glacial trough flooded by seawater C. A long ridge of glacial till D. A crescent-shaped sand dune with points downwind Explanation: A fjord is a long, narrow, deep inlet of the sea between high cliffs, typically formed by submergence of a glaciated valley. 18 / 2018. What are moraines? A. Deep, bowl-shaped basins carved by glaciers B. Crescent-shaped sand dunes with points downwind C. Long ridges of glacial till D. Sorted and stratified sediment deposited by glacial meltwater Explanation: Moraines are linear landforms composed of glacial till, deposited at the sides, base, or terminus of a glacier. 19 / 2019. What are the most dynamic and destructive geological agents? A. Coastal processes B. Running water C. Glaciers D. Wind Explanation: Coastal processes are the most dynamic and destructive geological agents due to the constant interaction of waves, currents, and tides with the land. 20 / 2020. What are outwash plains? A. Flat plains formed by the deposition of glacial meltwater B. Crescent-shaped sand dunes with points downwind C. Long ridges of glacial till D. Deep, bowl-shaped basins carved by glaciers Explanation: Outwash plains are flat or gently sloping areas of sediment deposited by meltwater streams flowing out from a glacier.
