Soil and Erosion
Water Erosion
Dissolved Load
composed of ions in a solution
usually carried to ocean
Suspended Load
sediments carried as solids
velocity determines size of particles
greater streams that carry larger particles have greater competence
sand, silt, and clay
gradient=slope
Bed Load
particles are too big to carried by the stream
bumped and knocked against the bed of the river
no continuous movement
saltation
high velocity and steep rivers cut down on bed load quickly
Streams
Headwaters
mountains
beginning of river
steep gradients
fast
gets rid of bed load
Meander
stream is lower
as stream eroded banks creates curves in streams
Floodplains
flatter ground
stream erodes banks
flat level area that surrounds the stream
wider than the rest of he stream
velocity of the stream has decreased
Base Level
where stream meets big body of water
higher the elevation the further from the base level the stream is
Deposition
creates meanders
starts when gradient starts to disappear closer to the base level
Delta
triangle shaped
stream meets a still body of water
Alluvial Fan
fan shaped
stream comes from steep slope into a valley
Ground Water
Erosion
works to dissolve rocks
Cave Formation
water travels along cracks
dissolves rocks in cracks and they get bigger
Cave Developments
Stalagmites
calcium carbonate builds up on the floor
g=ground
Stalactites
form as calcium-carbonate drips from the ceilings of caves
c=ceiling
Deposition
flow of water underground
