Term

 

weathering

Definition
  • chemical or mechanical process that beaks down and changes rocks on or near Earth's surface
  •  rate is infuenced by factors such as precipitation and temperature 
Term

 

deposition

Definition

removal and transport of weathered materials from one location to another; agents such as

  • water
  • wind
  • glaciers
  • gravity
Term

 

deposition

Definition
occurs when eroded materials are dropped in another location
Term

 

agent of erosion

Definition

forces that move or transport sediment:

  • wind, water, gravity, ice, waves
Term

 

gradient

Definition
the rate of change from place to place within a feild; also called slope
Term

 

discharge

Definition
measuere of volume of stream water that flows over a speicfic location in a particular ammount of time
Term

 

sediments

Definition
small pieces of rock that are moved and deposited by water, wind, glaciers, and gravity
Term

 

V-shaped valley

Definition
the characteristic shape of a valley eroded by a stream or rivers, as compared to a U-shaped valley
Term

 

U-shaped valley

Definition
the characteristic shape of a valley after it has been eroded by glaciers, especially mountain glacier, as compared to the V-shaped valley eroded by streams
Term

 

moraine

Definition
ridge or layer of mixed debris deposited by a melting glacier
Term

 

delta

Definition
triangular deposit, usually made up of silt and clay particles that forms where a stream enters a large body of water
Term

 

flood plain

Definition
broad, flat, fertile area extending out from a stream's bank that is covered with water during floods 
Term

 

abrasion

Definition
process of erosion in which wind-blown or water borne particles, such as sand, scrape aginst roeck surfaces or other materials and wear them away
Term

 

meander

Definition

 

curve or bend in a stream formed when a stream's slope decreases, water builds up in the stream's channel and moving water eroded away the sides of the stream bed

Term

 

dynamic equilibrium

Definition
a condition of the balancing out of opposing forces or actions, such as evaporation and condensation
Term

 

glacier

Definition
large, moving mass of ice that forms near Earth's poles and in mountinous regions at high elevation
Term

 

sandbar

Definition
a pile or low ridge of sand, often just above or just below water level, deposited by waves and currents; found near ocean shores or within streams and rivers
Term

 

drumlin

Definition
elongated landform that results when a glacier moves over an older moraine
Term

 

kettle lake

Definition
a lake formed when runoff and precipitation filled a kettle hole, which is a depression that formed when an ice block from a continental glacier became covered with sediments and melted
Term

 

outwash plain

Definition
area at the leading edge of a glacier, where outwash is deposited by meltwater streams
Term

 

plateau

Definition
a relatively flat-topped area
Term

 

ridge

Definition
a long, narrow, high, steep-sloped part of the landscape that is usually part of a mountain range
Term

 

escarpment

Definition
a steep slope or cliff in layered rocks; often formed from certain rock layer that are resistant to wathering and erosion
