15 Questions
What are some ways in which wind can erode rock?
Wind erodes rock through abrasion, as high-speed sediments gradually tear away at rock surfaces.
How does wind deposit sediments?
Wind can deposit sediments by blowing fine dust all around the globe, creating accumulations of wind-blown dust on the ocean seafloor, or through dust storms and volcanic eruptions.
What role does wind play in shaping desert landscapes?
Wind moves sand to form sand dunes and creates desert pavement by blowing sand and dust off the ground.
What is the primary cause of erosion in deserts?
Water, particularly from occasional flash floods, is the primary cause of erosion in deserts.
How are shorelines shaped?
Shorelines are shaped by the action of ocean waves and longshore currents that pick up and transport sediment.
How do waves erode headlands?
The force of waves erodes headlands.
What happens to coastlines over time?
Coastlines tend to become straighter over time.
Name one process that can produce new headlands and bays.
Deposition of sediments at river deltas, changes in global or regional sea levels, and disruptive erosion or deposition due to storms.
What is the name of the process that explains the presence of folded metamorphic rocks in old mountains?
Isostatic rebound.
Explain the principle of isostasy.
Thicker crust floats more deeply in Earth’s mantle, and thinner crust floats less deeply.
What is the result of tectonic plate collision in terms of isostatic pressure?
The isostatic pressure becomes imbalanced.
What happens to the crust during the process of isostatic rebound?
The whole crust rebounds upward.
What are some examples of metamorphic rocks that can be exposed at the surface as a result of the isostatic rebound?
Marble, slate, and gneiss.
What is the name of the principle that explains why the continental crust gets pushed down into the mantle during tectonic plate collision?
Isostasy.
What is the name of the process that causes the crust to gradually rebound during the erosion of mountains?
Isostatic rebound.
