1 Mathematician Science EOG Review: Landforms Vocabulary Definition Term canyon deep, large, V- shaped valley formed by a river over millions of years of erosion; sometimes called gorges (example: Linville Gorge in North Carolina) Picture deforestation when trees are removed from a forest contour lines a line on a topographic map the shows elevation (one line = same elevation) deposits left over particles

soil that falls down the side of a mountain, erodes

can also be caused by an increase in precipitation

2 drought lack of water or precipitation, a lengthy period of dry weather flood plain low areas near the river bank, covered by water when the river overflows its bank landslide flood pile of rock or soil that falls down the side of a mountain, erodes mountains and changes the shape of the mountain, can also be caused by an increase in precipitation once the land is saturated and there is an overflow of water

3 model three-dimensional (3-D) representation plain nearly level area that has been eroded or where material has been deposited reforestation when native trees are replanted in areas where deforestation has occurred drainage basin system of rivers and streams that drain in one area delta fan-shaped deposit of sediment at the mouth of a stream

4 dune mound or hill of wind-blown sand dam erosion built across a body of water, slows the movement of water behind it, creates large reservoir for water supply, decreases erosion wearing away of earth materials by water, wind, or ice water cycle the movement of water from earth to the atmosphere, a continual process weathering, chemical when rock is broken down by removing/changin g elements (i.e. weathering from carbon dioxide, CO2, acid)

5 windbreak row(s) of tall trees that prevent the wind from carrying off too much topsoil valley low area of land between higher land, often where a river flows tributary stream that flows into a larger river symbol picture on a map that represents a land feature soil terracing step-like formations for crops, slows the flow of water downhill and decreases runoff

6 sustainable practices farming practices that reduces the environmental impact (i.e. reducing runoff) reservoir artificial lake used to store water, mostly man-made saturated when no more water can me held scale relates map distance to real life distance (example: 1 cm = 1 mile)

7 sediment tiny bits of earth particles transported and deposited by water, wind, or ice slope steepness or incline, more steep = more erosion topographic map a two-dimensional (2-D) representation of the elevation of the land vegetation plants, shrubbery (shrubs), trees, etc.; roots help to hold the soil together to prevent erosion

8 weathering when rock is broken down to smaller pieces (the breaking down of particles) landforms features on the earth s surface hydroelectric electricity generated by moving water meander loop or curve in a river mouth where the river flows into the ocean

9 silt finely ground rock weathering, mechanical when rock is broken down by smaller pieces of wind, by water, by ice or heat (physically broken down) contour interval the distance between contour lines beach flash flood gently sloping shore next to a body of water, washed by waves or tides, often covered by sand or pebbles when an abundance of water rises and falls rapidly

10 weathering, biological caused by living organisms (ex.: animals that burrow, plant roots) water vapor water in the form of a gas aerial photographs a picture of the earth s surface taken from above gravity a constant force that pulls objects toward the center of the earth key explains information found on a map

11 erosion, glacial (glacier) the transport of soil or rock by a glacier (large moving body of ice) plateau a large nearly level area that has been lifted above the surrounding area runoff water that moves over the surface of the land precipitation a form of water that falls to the earth evaporation when liquid water changes to a gas (water vapor)

12 erosion, water the transport of soil or rock by water mountain high uplifted area with steep slopes erosion, wind the transport of soil or rock by wind condensatio n changes water from a vapor(gas) to a liquid logging cutting down of trees

13 levee natural or artificial wall of earth material along a river or sea that keeps the land from being flooded moraine Mound or ridge of unsorted soil and rock deposited directly by glacial ice fjord Long, deep, U- shaped valley inlet formed by a glacier and filled with sea water clear-cut When all of the trees in an area are cut down, easy but not the best for the environment
