What is Weathering?
The destructive process that
breaks down and changes
rocks that are exposed to
Earth’s surface
What are the 4 agents of
Weathering?
1. Water
2. Wind
3. Ice
4. Gravity
What does soluble mean? Give
an example of a substance
being soluble.
What is Chemical
Weathering?
Minerals and rocks at earth’s
surface weakens and breaks
down from exposure to water
and gases in the atmosphere &
changes the mineral
Composition
What is the strongest acid
type of acid rain?
What is Physical Weathering?
When carbon dioxide reacts
with water, what is formed?
What is the most common
agent of chemical weathering?
Sulfur Dioxide combined with
oxygen & water = sulfuric acid
Carbonic acid
Water
What are some pollute in the
air that reacts with oxygen to
generate acid rain.
What is found in the soil
profile of horizon A?
What is found in the soil
profile of horizon B?
Topmost layer of the soilcontains: small rocks,
minerals, humus, and dark
material due to organic
material
What is Transported Soil?
Dissolved minerals containing
clay, and is generally red or
brown
When the substance can be
dissolved. Example is sugar
dissolving in water
Sulfur dioxide, carbon dioxide
What is found in the soil
profile of horizon C?
What is Residual Soil?
Weathered parent material or
bedrock
Soil that remains in the same
location in which it was
formed
Breaking down of rock into
smaller pieces WITHOUT
changing its mineral
composition
Developed from weathered
material that has been moved
to a new location by wind,
water, and glaciers
What are the 3 agents of
chemical Weathering?
1.water
2. acid
3. oxygen
List examples of:
1. Chemical Weathered
objects.
Rust, statues turn green,
rocks starts to sizzle,
2. Physical weathered objects
Frost wedging, animals
burrowing, root growth
