Weathering And Erosion

Front 1

abrasion

Back 1

the grinding and wearing down of rock surfaces by other rock or sand particles

Front 2

breaking wave

Back 2

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.

Front 3

chemical weathering

Back 3

breakdown of rock's composition caused by the effects of chemicals on them

Front 4

delta

Back 4

a very fertile flat land made of silt left behind as a river drains into a larger body of water.

Front 5

erosion

Back 5

wearing away and moving particles of soil and rock by water, ice, and other agents.

Front 6

Sandblasting

Back 6

An erosional process by which blowing sand impacts and abrades rock surfaces resulting in shaped landscape features and new sediments.

Front 7

sediment

Back 7

Particles or materials formed by the weathering and erosion of rocks or organic material.

Front 8

stream

Back 8

Water flowing through a channel on land.

Front 9

stream abrasion

Back 9

The rounding, smoothing, and size reduction of sediments resulting from rolling, sliding, or bouncing of solid elements along a stream bottom.

Front 10

stream channel shape

Back 10

The shape of the body of rock or loose materials that confine the stream

Front 11

Tributary

Back 11

small stream or river that flows into a larger stream or river

Front 12

U-shaped valley

Back 12

The characteristic shape of a valley that forms when a glacier erodes a river valley from its original shape to a U shape.

Front 13

V-shaped valley

Back 13

The characteristic shape of a valley eroded by a stream or river, as compared to a U-shaped glacial valley.

Front 14

watershed

Back 14

The area of land drained by any one stream, also called a drainage area.

Front 15

weathering

Back 15

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.

Front 16

Finger Lake

Back 16

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.

Front 17

Flood Plain

Back 17

A nearly level plain that borders a stream that is subject to flooding unless protected artificially.

Front 18

Glacial Groove

Back 18

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.

Front 19

Glacial Parallel Scratches

Back 19

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.

Front 20

Glacial

Back 20

A large mass of naturally formed ice on land that moves downhill due to gravity.

Front 21

Mass Movement

Back 21

Any variety of erosion and deposition done directly by gravity.

Front 22

Meander

Back 22

A curve or bend in a stream or river.

Front 23

Physical Weathering

Back 23

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.

Front 24

Sandbar

Back 24

A pile or low ridge of sand, often just above or just below water level, deposited by waves and currants.
