processes
Learning Objectives:
• describe how rocks undergo weathering;
• identify the agents of erosion; and
• explain how the products of weathering are
carried away by erosion and deposited
elsewhere.
ROCK CYCLE
exogenic processes
geologic processes that occur on the surface of the Earth.
(External)
Weathering occurs in situ (in place) that is, particles stay put
and no movement is involved.
Types of Weathering
• Mechanical Weathering/Physical weathering -
is the breakdown of rocks into pieces without
any change in its composition.
2. Chemical Weathering- there are changes in the
composition of rocks due to the chemical reactions
