Formations
Dune
The tell for the amount of weathering a rock has gone through.
Color
Valuable topsoil containing equal parts sand and silt with about half as much clay.
Loam
The process in which layers of rock flake off to form rounded boulders.
Exfoliation YOU’VE WON 1,000,0- oops wrong one here like 5 points
The general term for all downhill movement of rocks and soil due to gravity.
Mass Wasting
A layer of soil resulting from the weathering of bedrock.
Horizon
The usual chemical balance of soils in rainy or wet climates.
Acidic
The well mixed combination of rocks, pebbles, sand, and silt carried by glaciers.
Glacial Till
When water enters a crack in a rock, expands as it freezes, and cracks the rock.
Frost Wedging (+500)
Strip cropping, wind breaks, and flood control dams are methods to fulfill this.
Soil Conservation
A bowl-shaped depression caused by strong winds blowing away an area’s loose materials.
Blowout

Landslide
Long, streamlined hills composed of unsorted glacial till.
Drumlin
Medial
Most of a stream’s sediment load are these.
Suspended Sediments
The upward thrust of rocks and boulders above the surface due to water freezing and expanding below them.
Frost Heaving (+499)
A type of mass wasting that moves quickly, but slips just a short distance.
