1
downslope movements of rocks, regolith and soil because of gravity.
mass movement
2
process in which some of the minerals in rocks are directly dissolved in water.
solution
3
result of the absorption or combination of water and a particular substance on the rock, leading to change in shape
hydration
4
contribute to both mechanical and chemical weathering.
plants
5
process involving the formation of various types of carbonates in rocks.
carbonation
6
carthworms, rabbits, termites and breakdown the rock burrowing.
animals
7
play a very important role in the weathering of rocks.
Provisions for agriculture,
construction of houses, and construction of roads, among others require large amounts of rocks to be broken down.
humans
8
weathering or disintegration of rocks caused by living organisms
biotic
9
happens when winds carry vast quantity of fine soil particles and sand away from a region, spreading it over adjoining cultivated land and destroying their fertility.
wind erosion
10
removal of soil in water channels or drainage
lines.
gully erosion
11
involves the movement of weathered rocks (now soil, sand or pebbles) from their site
of
weathering
erosion
12
the removal of thin layers of soil because of surface runoff and rain. This type of erosion is common along river beds and areas affected by flood
sheet erosion
13
removal of soil by the action of concentrated running water.
This process
creates numerous centimetre deep tiny channels
rill erosion
14
caused by successive heating and cooling which causes the expansion and contraction of rocks.
block disintegration
15
The combined action of all physical and chemical processes that disintegrate and decompose rocks near Earth's surface
weathering
16
refers to the alternate freezing and thawing of water inside the joints of the rock, causing them to split into small particles or fragments
frost weathering
17
can all causes physical weathering. Tiny grains of sand are picked up and carried off by the wind, which are then blasted
on the surface
rocks,
smoothening them. This could wear away the rock and weather it.
wind and waves weathering
18
also known
as
mechanical weathering refers to the breakdown of rocks without change in its composition
Pause
physical weathering
19
stripping of the outer layer of rocks due to intense hearing. The successive expansion and contraction of the outer layers of the rock peels off from the main rock in the form of concentric shells
exfoliation
20
is the
weakening or disintegration of rocks and the formation of compounds or new substances caused by chemical reactions.
