Earth's Surface Processes

What is the term for the process of wind removing the top layer of fine sediment, leaving behind rocks that are too heavy to be lifted?

What type of glacier forms in a mountain area, creating a rugged landscape?

What is the term for the extremely slow movement of materials downslope?

What is the term for the process of wind carrying extremely fine material long distances?

What is the term for the process of glaciers moving and depositing materials?

What is the term for the sudden rapid movement of a large amount of material downslope?

What is the term for the grinding and wearing down of rock surfaces by other rock or sand particles?

What is the term for thick sheets of ice that may spread over entire continents?

Wind shapes the Earth through abrasion, deflation, dunes, and loess
Abrasion is the grinding and wearing down of rock surfaces by other rocks or sand particles
Deflation is the removal of top layers of fine sediment by wind, leaving behind rocks that are too heavy to be lifted
Dunes are mounds of wind-deposited sand that move in the same direction as the wind
Loess is a thick deposit of fine-grained sediment carried long distances by wind

Ice shapes the Earth through glacial drift, alpine glaciers, and continental glaciers
Glacial drift is the process of glaciers moving under gravity, picking up materials (erosion) and depositing them as they melt
Alpine glaciers form in mountain areas, creating rugged landscapes
Continental glaciers are thick sheets of ice that spread over entire continents, eroding and removing existing features

Gravity shapes the Earth through creep, rockfall, landslide, and mudflow
Creep is the extremely slow movement of materials downslope, influenced by factors such as water, plant roots, and burrowing animals
Rockfall is the sudden falling of loose rocks down a steep slope
Landslide is the sudden rapid movement of a large amount of material downslope
Mudflow is the rapid movement of a large mass of mud
