24 Cards in this Set

  • Front
  • Back
abrasion
the grinding and wearing down of rock surfaces by other rock or sand particles
breaking wave
The result of waves dragging on the ocean bottom causing the water in waves to fall forward as the waves bunch together, rise up, and break against the shore.
chemical weathering
breakdown of rock's composition caused by the effects of chemicals on them
delta
a very fertile flat land made of silt left behind as a river drains into a larger body of water.
erosion
wearing away and moving particles of soil and rock by water, ice, and other agents.
Sandblasting
An erosional process by which blowing sand impacts and abrades rock surfaces resulting in shaped landscape features and new sediments.
sediment
Particles or materials formed by the weathering and erosion of rocks or organic material.
stream
Water flowing through a channel on land.
stream abrasion
The rounding, smoothing, and size reduction of sediments resulting from rolling, sliding, or bouncing of solid elements along a stream bottom.
stream channel shape
The shape of the body of rock or loose materials that confine the stream
Tributary
small stream or river that flows into a larger stream or river
U-shaped valley
The characteristic shape of a valley that forms when a glacier erodes a river valley from its original shape to a U shape.
V-shaped valley
The characteristic shape of a valley eroded by a stream or river, as compared to a U-shaped glacial valley.
watershed
The area of land drained by any one stream, also called a drainage area.
weathering
The physical (mechanical) and chemical alterations of rock and other of Earth's materials at or near Earth's surface,that is exposed to the weather (elements),through temperature changes, water, chemical agents, atmospheric gases, and organic materials.
Finger Lake
A body of water that forms in a long, narrow U- shaped glacial valley, often partly dammed at one end by a mound of glacial moraine sediment.
Flood Plain
A nearly level plain that borders a stream that is subject to flooding unless protected artificially.
Glacial Groove
A long narrow channel or furrow on bedrock formed by the gouging and sanding actions of rocks and sediments frozen to the bottom of a glacier; show the direction of former glacial movement.
Glacial Parallel Scratches
Parallel cuts in bedrock formed by abrasion (gouging and sanding) of rocks
and sediments frozen to the bottom of a glacier; show the direction of former glacial movement.
Glacial
A large mass of naturally formed ice on land that moves downhill due to gravity.
Mass Movement
Any variety of erosion and deposition done directly by gravity.
Meander
A curve or bend in a stream or river.
Physical Weathering
The mechanical or physical breakdown of rock and other Earth materials at or near Earth's surface into smaller pieces (sediments) without change in the mineral or chemical composition.
Sandbar
A pile or low ridge of sand, often just above or just below water level, deposited by waves and currants.
