What is the primary role of biological weathering in rock breakdown?
Action of living organisms
Which type of weathering involves the addition or removal of chemical elements from rocks?
Chemical weathering
How does physical weathering contribute to the process of chemical weathering?
By increasing surface area for chemical attack
Which weathering process involves the breakdown of rock caused by living organisms such as burrowing animals and plants?
Biological weathering
What is the definition of weathering?
The physical and chemical alteration of rocks at or near the Earth's surface
How is weathering different from erosion?
Erosion involves transportation while weathering does not
What makes rocks vulnerable to weathering according to the text?
The presence of joints, cracks, and openings
In the context of weathering, what does the interface between lithosphere and atmosphere refer to?
A zone extending into the ground where air and water can penetrate
What role does transportation play in erosion?
Transportation is needed for movement of weathered debris
Which process is the initial phase in denudation according to the text?
Weathering
What type of weathering predominates in cold and dry regions?
Physical weathering
How does climate impact the rate of weathering in hot and moist regions?
It accelerates chemical decay
What kind of vegetation can accelerate the weathering process on rocks beneath it?
Coniferous forest
How does the period of exposure affect the magnitude of weathering on rocks?
The longer the exposure, the more intense the weathering
What type of debris can act as a weak acid sponge to accelerate weathering?
Permeable sandy debris
How does slope gradient influence the rate of weathering?
Steep slopes lead to faster water flow and higher infiltration
