19
Q

Flooding

A

Increase of water volume —> overflow

On FLAT land only

20
Q

Plants and flooding

A

Protects from erosion

Takes in would be run off water

21
Q

Relief

A

Difference in elevation

22
Q

Plains

A

Low relief
Flat
Horizontal SED bedrock
Rivers, valleys

23
Q

Plateaus

A

Mid. Relief
Horizontal SED bedrock
Catskills⭐️, dissected plateau

24
Q

Mountain

A

Highest relief
Extreme elevation
META IGN bedrock

25
Q

Arid climate

A

Dry
Steep slopes, angled rocks, no vege.
Thin soils
Phys. weathering

26
Q

Humid climate

A

Moist, gentle slopes, round rocks, lots of vege

Thick souls, chem. Weathering

27
Q

Radial drainage

A

Off slope

Diff. Directions off MOUNT

28
Q

Dendritic drainage

A

Flow off plains, low points
Flat water
Branches

29
Q

Trellis drainage

A

Flow off plateau
Faulted/folded rock
Flow through folds

30
Q

Annular

A

Erratic

A

Boulders leftover left behind from glaciers

33
Q

Surface ocean currents

A

Shallow currents in 1 cont. movement by prevailing winds

34
Q

Wave height

A

Wind speed
How long the wind blows
Distance wind has blown(fetch)

35
Q

Longshore drift longshore current

A

Carry sediments to beaches parallel to shore

36
Q

Jetty

A

Reduce erosion
Rock or wood walls
1 side deposition other erosion

37
Q

Breakwaters

A

Reduce erosion

Walls to lose wave and their carry power

38
Q

Groyne

A

Fences to limit carrying power of waves

Reduce erosion

39
Q

Spits

A

Narrow sandbars

Finger points to direction wave is going

40
Q

Longshore drift

A

Zigzag movement of sand

41
Q

Longshore current

A

Waves travel at angle transport sand

42
Q

Barrier islands

A

Sandbars that build up

43
Q

Isolines

A

Connected points of equal value on map w/similar measurements

44
Q

Meandering streams

A
Inside = depósitos
Outside = erosion
