the breakdown of a rock in place by chemical, physical or biologicl proccess acting on rocks close to or at the earths surface, with no movement of debris
wethering
1 of 12
a rock breaks apart when its individual grains get weakend (this could be due to chemical reactions attacking certain minerals or the onion skin efeect, with the expansion and contraction of the minerals)
granular disintrigration
2 of 12
when a rock brakes into blocks (any lines of weakness are attacked, like bedding planes or joints)
block disintrigration
3 of 12
grains of sediment come into contact with rocks they are traveling over
abrasion
4 of 12
when the load being carried by the river collides and rubs against itself, breaking up into smaller and smaller pieces. The rough edges also become smooth, forming smaller, rounder material.
attrition
5 of 12
material moved by the agent of eroision
load
6 of 12
debris/ fragments must be completely or partially in contact with ground
bed load
7 of 12
debris/ fragments must be completely in contact with ground
traction
8 of 12
the transport of material by bouncing
saltation
9 of 12
the transport of material in water or air, without touching the earths surface
suspension
10 of 12
transport of ions dissolved in water
dissolved load
11 of 12
is the degree to which particles are the same size
sorting
