Exogenic Process Flashcards
Is the process of disintegration(physical)
decomposition(chemical) of rocks
or breaking down of rocks into smaller particles
weathering
Produces smaller, angular fragments of the same rocks, such as scree
Disintegration
Refers to chemical weathering and create changes in rock
Decomposition
Two types of weathering
Mechanical weathering
Chemical weathering
breaking down of rocks without its composition
Mechanical weathering
(physical weathering)
There are changes in the composition of rocks due to chemical reaction
Chemical weathering
What are the mechanical weathering factors
Pressure, temperature, abrasion, organic activity, human activity, burrowing animals
Rocks or minerals are dissolved by water
Dissolution
Breaking down of rocks by acidic water produce clay and soluble salts
hydrolysis
Breaking down of rocks by oxygen in/and water, often giving iron-rich rocks a rusty-colored weathered surface
oxidation
Seperation and removal of weathered rocks due to different agents like water,wind,and ice
Erosion
Movement of sending downslope under the influence of gravity
Mass wasting
Settle down in a particular location
Deposition
Formed or occurring on the surface of the earth
exogenic
