Load transport

Question 1

load transport

Answer 1

traction, saltation, suspension and solution

Question 2

Load

Answer 2

amount of sediment transported by a river

Question 3

3 subgroups

Answer 3

bedload= pebbles

suspended load = smallest particles carried along in suspension

solution load = material dissolved in solution

Question 4

traction

Answer 4

process of transporting coarse bedload

rocks and pebbles more intermittently by sliding

intermittent because of uneveness in the channel such as turbulent flow + frictional resistance of the bed

only occurs when river energy levels are high

Question 5

saltation

Answer 5

skipping/ bouncing motion of sand sized particles
leapfrog each other
momentum idea = many saind grains begin to move as soon as some are in motion

Question 6

suspension

Answer 6

applies to the smallest particles - silt and clay

high velocities are required although once in suspension they can travel long distances
solution

Question 7

solution

Answer 7

streams draining areas of dissolvable minerals

most effective in humid tropical environments

takes place at frequent intervals
