1.
bed load: consists of sand, pebbles and cobbles
2.
carry capacity: total amount of sediment a stream carries
3.
cut bank: outside stream or river where erosion occurs and higher velocity. deep
4.
delta: the triangular deposit that forms where a stream enters into a large body of water
5.
deposition by mass movement: sediment at bottom of cliff/slope is poorly sorted
6.
deposition by wind: are layered and cross bedded, sand grains are highly sorted, rounded, frosted and pitted. wind direction controls shape of sand dunes.
7.
dissolved load: material is carried by solution
8.
divide: elevated land that divides one watershed or drainage basin from another
9.
drumlin: mounded moraine (glacial till) in shape of upside down spoon.
shows direction of movement, steeper slope on side glacier came from.
10.
erosion: involves transport. agents are wind, water, glaciers, and mass movement.
11.
erratic: large boulder different than bedrock
12.
flood plain: flat area that extends out from a streams bank and is covered by excess water during times of flooding
13.
glacial erosion: occurs where it is cold (high elevation, high latitude)
14.
gravity: most driving force behind all agents of erosion
15.
headwaters: the region where water first accumulates to supply a stream
16.
high velocity: = more erosion
17.
highest kinetic energy: with highest velocity, stream carrying capacity ( stream load )
18.
kettle lakes: chunks of ice break off as glacier retreats, outwash sediment then builds up around. ice melts then makes lake.
19.
kinetic energy: energy in motion (doing work)
20.
levees: forming sediment mounds
21.
moraine: unsorted, sub rounded material dropped by a glacier when glacier melts.
22.
outwash plain: melt water at end of glacier sorts and carries smaller sediment from glacier, makes layers.
23.
oxbow lake: part of lake that eventually dries up
24.
point bar: inside stream or river where deposition occurs and lower velocity. shallow
25.
potential energy: stored energy (available to do work)
26.
shoreline deposition: spit deposits in bays used to tell direction of longshore current. break walls and jetties used to block current and cause deposition.
27.
stream deposition: process by which sediments are released, dropped or settled from an erosional system. caused by loss of kinetic energy (velocity) in agent of erosion
28.
stream erosion: most responsible for shaping land.
29.
streams: have highest potential energy at highest elevation
30.
suspended: particles small enough to be held up by the turbulence of a streams moving water
31.
tributary: small stream or river that flows into a larger stream or river
32.
watershed: where all the lands area water drains into a stream
33.
wind erosion: dominates on arid (dry) regions, best sorter grains become frosted and pitted.
