2. VOCABULARY WORDS
Weathering
When a destructive
force breaks up and
wears away rocks on
Earth's surface
through physical and
chemical change
Physical
Weathering
Breaks rock down
through physical
change, no chemical
change
Chemical Weathering
Breaks rocks down through
chemical change, needs water,
creates particles that have a
different mineral composition
3. Types of rock that are physical and chemical
weathering
5. Physical weathering
Frost weathering is a collective term for several
mechanical weathering processes induced by
stresses created by the freezing of water into ice.
6. Chemical weathering
The erosion or disintegration of rocks, building materials, etc., caused
by chemical reactions (chiefly with water and substances dissolved in
it) rather than by mechanical processes.
7. Chemical and physical weathering
Weathering processes crack, wear away, and weaken rocks. Over time, it may
cause large changes to the landscape. Physical and chemical weathering
degrade rocks in different ways. While physical weathering breaks down a
rock's physical structure, chemical weathering alters a rock's chemical
composition. Physical weathering works with mechanical forces, such as
friction and impact, while chemical weathering takes place at the molecular
level with the exchange of ions and cations.

9. THIS IS MORE INFORMATION ABOUT THE ROCKS
PHYSICAL WEATHERING, ALSO KNOWN AS MECHANICAL
WEATHERING, IS THE CLASS OF PROCESSES THAT CAUSES THE
DISINTEGRATION OF ROCKS WITHOUT CHEMICAL CHANGE. THE
PRIMARY PROCESS IN PHYSICAL WEATHERING IS ABRASION
(THE PROCESS BY WHICH CLASTS AND OTHER PARTICLES ARE
REDUCED IN SIZE).
