Weathering And Erosion

Front 1

Stream Channel

Back 1

Narrow Pathway Carved into sediment or rock by the movement of surface water

Front 2

Stream Bank

Back 2

Grand bordering each side of a stream that keeps moving water confined

Front 3

Meander

Back 3

A Bend or curve in a stream channel caused by moving water

Front 4

Delta

Back 4

Triangular Deposit that forms where a stream enters a large body of water

Front 5

Flood plain

Back 5

Broad , flat area that extends out from a stream's band and is covered by excess water during times of flooding

Front 6

Discharge

Back 6

The measure of the volume of stream water that flows over particular location within given time.

Front 7

Bed Load

Back 7

Consists of sand, pebbles and cobbles that the stream's water can roll or push along the bed of a stream

Front 8

Solution

Back 8

Material carried in this after it becomes dissolved in stream water

Front 9

Divide

Back 9

High land area that separates one water shed from another

Front 10

Watershed

Back 10

Land area drained by a stream system

Front 11

Run Off

Back 11

water flowing down slope along earth's surface

Front 12

Loess

Back 12

thick wind -blown silt deposits

Front 13

Dune

Back 13

Overtime pile of wind blown development

Front 14

Ventifact

Back 14

Rocks shaped by wind-blown sediments.

Front 15

Abrasion

Back 15

Another process of erosion. Occurs when particles such as sand rub against the surface of rocks or other materials

Front 16

Deflation

Back 16

The lowering of land surface that result from the wind's removal of surface particles

Front 17

Weathering

Back 17

process by which rocks on or near earth's surface break down and change.

Front 18

Erosion

Back 18

Removal and transport of weathered material from one location to another

Front 19

Mechanical weathering

Back 19

Process by which rocks and minerals break down into smaller pieces

Front 20

Frost wedging

Back 20

Repeated thawing and freezing of water in the cracks of rocks

Front 21

Exfoliation

Back 21

Process by which other rock layers are striped away

Front 22

Chemical weathering

Back 22

Process by which rocks and mineral undergo changes in their composition as the result of chemical reactions.

Front 23

Oxidation

Back 23

Chemical reaction of oxygen with other substances

Front 24

Deposition

Back 24

Final stage of erosional process. the natural process of laying down a deposit of something

Front 25

Rill erosion

Back 25

Running water in small channels , on side of a slope

Front 26

Mudflows

Back 26

Swiftly moving mixtures of mud and water

Front 27

Landslide

Back 27

A rapid, down slope movement of earth materials that occurs when a relatively thin block of lose soil , rock , debris separates from underlying bedrock

Front 28

Slump

Back 28

When the mass of material in landslide rotates and slodes along a curved surface.

Front 29

Avalanche

Back 29

Landslide that occur in mountainous areas with thick accumulations of snow

Front 30

Mass Movement

Back 30

Down slope movement of loose sediments and weathered rock resulting the force of gravity.

Front 31

Creep

Back 31

Slow steady downhill flow of loose, weathered earth materials , especially soils.
