The breaking down of rock by physical processes.
What is mechanical weathering?
When chemical interactions in the environment react with minerals in rock to break it down.
Sediment from weather rock mixes with water air and organic material to form _________.
What is soil?
Caves are most likely to form in this rock type.
What is Limestone?
__________ weathering is the process by which softer, less weather resistant rocks wear away at a faster rate than harder, more weather resistant rock.
What is differential?
The collision of rocks resulting in the breaking and weathering away of material. Agents include running water and wind.
What is abrasion?
When compounds in the atmosphere mix with water vapor to produce weak acids and then fall back to earth.
What is carbonation?
The deep red color of soil found in Georgia and other warm humid regions is caused by ______ oxides.
What is iron?
The image shows weathering in limestone.
What is the name of landscape that is created
underground due to weathering limestone?
Karst Topography
Use the graph to answer.
AYT 20 C, AYP 150 cm
STRONG CHEMICAL WEATHERING
A mechanical weathering process when tree roots grow and expand in the cracks of rocks
What is root wedging?
Chalk and limestone dissolve in water because rainwater contain a weak _________ acid. (The most common natural acid on the planet.)
What is carbonic acid?
__________ rock has the greatest impact on soil composition.
What is parent rock?
A natural opening, usually in rocks, that is large enough for human entry.
What is a cave?
Use the graph to answer.
AYT 0 C, AYP 50 cm
SLIGHT FROST ACTION
A mechanical weathering process when water freezes and expands in the cracks of rocks.
What is ice wedging?
When minerals react with oxygen in the air and turns iron mineral a brown-red color.
What is oxidation?
Use the soil triangle to answer.
25% clay, 55% sand, 20% silt
SANDY CLAY LOAM
Circular depression that forms when rocks dissolve.
What is a sinkhole?
Use the particle size image to correctly label clay, silt, & sand.
sand - X
silt - Y
clay - Z

Which of the soil layers contains the greatest number of biological organisms?
H
What type of weathering forms Karst landforms?
Carbonation
Which layer is bedrock?
K
