Glacial melting
-
Ice sheet ablation
C
Correct answer
Explanation
Glacial melting is the term used to describe the process of ice sheets and ice caps melting and forming meltwater lakes.
What is the term used to describe the process of ice sheets and ice caps moving and flowing?
-
Ice sheet flow
-
Ice cap flow
-
Glacial flow
-
Ice sheet movement
C
Correct answer
Explanation
Glacial flow is the term used to describe the process of ice sheets and ice caps moving and flowing.
What is the term used to describe the process of ice sheets and ice caps forming and accumulating?
-
Ice sheet formation
-
Ice cap formation
-
Glacial formation
-
Ice sheet accumulation
C
Correct answer
Explanation
Glacial formation is the term used to describe the process of ice sheets and ice caps forming and accumulating.
In canyoning, what is the term for a natural, narrow passage with steep walls and flowing water?
-
Gorge
-
Canyon
-
Ravine
-
Gully
B
Correct answer
Explanation
A canyon is a deep, narrow valley with steep sides, typically formed by the erosive action of water over time.
What is the term for a hiking trail that follows a river or stream?
-
Riverside trail.
-
Streamside trail.
-
Waterfront trail.
-
Riparian trail.
D
Correct answer
Explanation
A riparian trail is a hiking trail that follows a river or stream and is typically located within a riparian zone, which is the area of land adjacent to a river or stream.
What is the term for the process by which salts are transported from the soil to the groundwater?
-
Leaching
-
Percolation
-
Infiltration
-
Runoff
A
Correct answer
Explanation
Leaching is the process by which salts are transported from the soil to the groundwater.
What is the term for the process by which salts are deposited on the soil surface by evaporation?
-
Saline deposition
-
Salt crusting
-
Efflorescence
-
All of the above
D
Correct answer
Explanation
Saline deposition, salt crusting, and efflorescence are all terms used to describe the process by which salts are deposited on the soil surface by evaporation.
Which geological phenomenon is responsible for the formation of caves?
-
Erosion by wind
-
Volcanic activity
-
Dissolution of soluble rocks by water
-
Metamorphic processes
C
Correct answer
Explanation
Caves are typically formed through the process of dissolution, where water seeps through cracks and joints in soluble rocks like limestone or dolomite, gradually dissolving and enlarging the openings over time.
What is the term used to describe the process of rock breakdown due to physical weathering?
-
Exfoliation
-
Hydrolysis
-
Carbonation
-
Frost wedging
D
Correct answer
Explanation
Frost wedging is a physical weathering process where water seeps into cracks and joints in rocks, freezes, expands, and exerts pressure, causing the rock to break apart.
Which geomorphic agent is primarily responsible for the formation of sand dunes?
-
Glaciers
-
Wind
-
Rivers
-
Volcanoes
B
Correct answer
Explanation
Wind is the primary geomorphic agent responsible for the formation and movement of sand dunes. Wind picks up and transports sand grains, causing them to accumulate and form dunes in areas with sufficient wind energy.
What is the term used to describe the process of soil formation?
-
Weathering
-
Erosion
-
Deposition
-
Pedogenesis
D
Correct answer
Explanation
Pedogenesis refers to the process of soil formation, where various factors such as climate, parent material, topography, and biological activity interact to transform weathered rock material into soil.
What is the term used to describe the process of rock breakdown due to chemical weathering?
-
Exfoliation
-
Hydrolysis
-
Carbonation
-
Frost wedging
B
Correct answer
Explanation
Hydrolysis is a chemical weathering process where water reacts with minerals in rocks, breaking them down and altering their composition.
Which geomorphic feature is formed by the erosive action of a river?
-
Sand dunes
-
Meanders
-
Cirques
-
Moraines
B
Correct answer
Explanation
Meanders are sinuous bends in a river's course, formed as the river erodes and deposits sediment along its banks.
What is the term used to describe the process of rock breakdown due to temperature changes?
-
Exfoliation
-
Hydrolysis
-
Carbonation
-
Frost wedging
A
Correct answer
Explanation
Exfoliation is a physical weathering process where concentric layers of rock peel off due to temperature variations, causing the rock to break down.
Which geomorphic feature is formed by the deposition of sediment by a glacier?
-
Sand dunes
-
Meanders
-
Cirques
-
Moraines
D
Correct answer
Explanation
Moraines are ridges or mounds of sediment deposited by glaciers at their terminus or along their sides.
