Geomorphic Processes Questions
What is the process by which coral reefs grow and expand?
-
Accretion
-
Erosion
-
Subduction
-
Metamorphism
A
Correct answer
Explanation
Coral reefs grow and expand through a process called accretion, where new coral colonies form on top of existing ones.
What is the term used for the process of removing soil or rock from a site to create a level surface for construction?
-
Excavation
-
Grading
-
Compaction
-
Trenching
A
Correct answer
Explanation
Excavation is the process of removing soil or rock from a site to create a level surface for construction or to make way for foundations, basements, or other underground structures.
What is the process by which water dissolves limestone and forms caves?
-
Erosion
-
Weathering
-
Dissolution
-
Percolation
C
Correct answer
Explanation
Dissolution is the process by which water dissolves limestone and forms caves. Water containing carbonic acid, formed when carbon dioxide from the atmosphere dissolves in water, reacts with limestone to form calcium bicarbonate, which is then carried away by water.
What is the term for a cave formation that is formed by the deposition of calcium carbonate from flowing water?
-
Stalagmite
-
Stalactite
-
Flowstone
-
Soda straw
C
Correct answer
Explanation
Flowstone is a cave formation that is formed by the deposition of calcium carbonate from flowing water. It typically forms on cave walls and floors.
What is the term for a cave passage that is formed by the collapse of a cave roof?
-
Canyon
-
Gorge
-
Valley
-
Breakdown
D
Correct answer
Explanation
A breakdown is a cave passage that is formed by the collapse of a cave roof. It is typically characterized by large blocks of rock and rubble.
What is the term for a cave passage that is formed by the erosion of a stream?
-
Canyon
-
Gorge
-
Valley
-
Meander
D
Correct answer
Explanation
A meander is a cave passage that is formed by the erosion of a stream. It is typically characterized by a sinuous course and a series of pools and riffles.
What is the term for a cave passage that is formed by the erosion of wind?
-
Blowhole
-
Karst window
-
Natural bridge
-
Sinkhole
A
Correct answer
Explanation
A blowhole is a cave passage that is formed by the erosion of wind. It is typically characterized by a narrow opening at the surface and a wider chamber at the bottom.
What is the term for a cave passage that is formed by the erosion of ice?
-
Ice cave
-
Glacier cave
-
Permafrost cave
-
Sea cave
A
Correct answer
Explanation
An ice cave is a cave passage that is formed by the erosion of ice. It is typically characterized by the presence of ice formations, such as stalactites, stalagmites, and flowstone.
What is the term for a cave passage that is formed by the erosion of waves?
-
Sea cave
-
Coastal cave
-
Tidal cave
-
Wave-cut cave
A
Correct answer
Explanation
A sea cave is a cave passage that is formed by the erosion of waves. It is typically characterized by a narrow opening at the surface and a wider chamber at the bottom.
What is the term for a cave passage that is formed by the erosion of volcanic activity?
-
Lava tube
-
Volcanic cave
-
Magma cave
-
Pyroclastic cave
A
Correct answer
Explanation
A lava tube is a cave passage that is formed by the erosion of volcanic activity. It is typically characterized by a long, narrow tunnel that was formed by the flow of lava.
What is the term for a cave passage that is formed by the erosion of human activity?
-
Mine
-
Quarry
-
Tunnel
-
Catacomb
A
Correct answer
Explanation
A mine is a cave passage that is formed by the erosion of human activity. It is typically characterized by a series of tunnels and chambers that were excavated to extract minerals or other resources.
What is the term used to describe the process of ice loss from glaciers and ice sheets?
-
Glacial retreat
-
Ice sheet collapse
-
Calving
-
Ablation
A
Correct answer
Explanation
Glacial retreat refers to the process of ice loss from glaciers and ice sheets, typically caused by melting or sublimation.
What is the term used to describe a steep slope or cliff of ice at the edge of a glacier or ice sheet?
-
Icefall
-
Serac
-
Bergschrund
-
Crevasse
A
Correct answer
Explanation
An icefall is a steep slope or cliff of ice at the edge of a glacier or ice sheet.
What is the term used to describe the movement of soil and rock caused by the freeze-thaw cycle in permafrost regions?
-
Cryoturbation
-
Thermokarst
-
Pingos
-
Needle ice
A
Correct answer
Explanation
Cryoturbation is the movement of soil and rock caused by the freeze-thaw cycle in permafrost regions, resulting in the formation of various features such as patterned ground and frost boils.
What is the term used to describe the process of permafrost formation?
-
Cryoturbation
-
Thermokarst
-
Pingos
-
Needle ice
A
Correct answer
Explanation
Cryoturbation is the process of permafrost formation, involving the freezing of soil and rock and the formation of ice lenses.
