Watershed Sol 6.7 (Benton)

Front 1

Channel

Back 1

the bed of a stream or river, the path of ground through which a river flows

Front 2

Confluence

Back 2

the point where two rivers flow together

Front 3

Contour line

Back 3

a line on a topographic map that shows elevation above sea level

Front 4

Divide

Back 4

A ridge of land forming the highest points in a watershed

Front 5

Erosion

Back 5

The wearing away of Earth’s surface when soil or rock is loosened (for example, by wind or water) then moved from one place to another.

Front 6

Estuary

Back 6

A body of water formed where fresh water and salt water meet, and are mixed by tides. Salinity in an estuary varies

Front 7

Features

Back 7

the recognizable attributes of an area including landforms, vegetation, structures, and bodies of water.

Front 8

Flood plain

Back 8

Wide flat border areas of rivers and stream onto which water spills out at times of high water flow.

Front 9

Ground water

Back 9

Water that soaks into the ground and collects in the spaces between soil and rock particles.

Front 10

Landforms

Back 10

a natural feature of a land surface

Front 11

Meanders

Back 11

Large bends in a stream formed when a stream begins to erode its banks more than the channel bottom

Front 12

Natural features

Back 12

The attributes of an area that are not created by human power including landforms, vegetation, and bodies of water.

Front 13

Non-point source pollution

Back 13

pollution that enters the water from a variety of sources including homes, farms, streets, and construction sites

Front 14

Oxbow lakes

Back 14

A crescent-shaped lake formed when a meander of a river or stream is cut off from the main channel

Front 15

Point source

Back 15

pollution that enters the water from a single location as a concentrated source

Front 16

Ridgeline

Back 16

A long narrow chain of hills or mountains

Front 17

River

Back 17

A river is a stream of water of considerable volume, which travels downhill (from higher altitudes to lower altitudes due to gravity).

Front 18

River mouth

Back 18

the point where a smaller body of water enters a larger body of water

Front 19

River source

Back 19

the point of origin of a stream or river

Front 20

Runoff

Back 20

Water that flows over the land and eventually flows into lakes, rivers or streams

Front 21

Stream

Back 21

A natural body of flowing water. Streams are characterized by their order (or stream size). The joining of two first order (smallest size) streams creates a second order stream. In turn, the joining of two second order streams create a third order stream.

Front 22

Structure

Back 22

something that is made by human power, something that is constructed

Front 23

Symbol

Back 23

something that stands for or suggests something else by reason of relationship, association, convention, or accidental resemblance

Front 24

Topographical Map

Back 24

a map that shows elevation of a land area through the use of contour lines

Front 25

Tributaries

Back 25

a stream feeding a larger stream or lake

Front 26

Water quality monitoring

Back 26

The collection of water samples to analyze chemical and or biological parameters.

Front 27

Watershed

Back 27

The land water flows across or through on its way to a stream, lake or wetland.

Front 28

Watershed divide (or boundary)

Back 28

An elevated area, such as a ridgeline or divide, that separates one watershed from another

Front 29

Wetlands

Back 29

The transition zone between dry land and permanent bodies of water such as rivers, lakes or bays. Wetlands may be completely or partially covered by water at different times of the year.

Front 30

Boundary

Back 30

the limit or border of an area
a. political -a political boundary is artificially determined
b. natural -a natural boundary is marked by a landform such as a river

Front 31

Chesapeake Bay
