What role does weathering play in the formation of soil?
weathering occurs faster in warm and rainy climate. the rate of which soil forms depends on the climate and type of rock. so soil formation is faster when weathering is quicker too.
How can physical weathering increase the rate of chemical weathering?
Physical weathering breaks rock down into much smaller pieces and gives the original rock a much greater surface area which, when exposed to chemical agents such as carbonic acid, reacts at a much faster rate than it would had the larger rock not undergone physical weathering.
A rock will weather faster after it has been crushed because it?
The crushed rock pieces have a greater surface area then whole rock giving more exposure to weathering.
How does air pollution affect the rate of weathering?
If the air pollution is strong it will weather away the rock faster
What increases the rate of chemical weathering of rock?
Chemical weathering can be increased if rainwater has is more acidic. Meaning it has a pH level higher than 5.5. Chemical weathering occurs quicker in warm and moist climates. :)
How does freezingwater cause the weathering of rocks?
Water can get into fractures/joints/pores of rock, freeze, and then expand, weathering the rock.
Does weathering go with metamorphic or igneas or sedimentary?
Weathering can happen to any rock. It is the first stage in the process that leads to the formation of sedimentary rock.
WHAT ROLE DOES WEATHERING PLAY IN THE FORMATION OF WEATHERING?
weathering occurs faster in warm and rainy climate. the rate of which soil forms depends on the climate and type of rock. so soil formation is faster when weathering is quicker too.
How does release of pressure affect mechanical weathering?
There are two main types of weathering: mechanical (also called 'physical') and chemical. Pressure release is a form of mechanical weathering. Pressure release usually occurs when rock that has been deeply buried, rises toward the surface due to the erosion of the mass of rock above it. Pressure release causes fractures and exfoliation in the depressurizing rock body. These fractures in the rock make it more susceptible to, and accelerate, other modes of mechanical weathering attack, such as freeze/thaw hydraulics and plant root growth.
What Is geologe?
When a mass of rock is exposed by weathering and by removal of the overlying rock there is a decrease in the confining pressure on the rock, and a slight expansion of the rock volume. This unloading promotes cracking of the rock – known as exfoliation - and the development of cracks leads to other kinds of weathering.
What are the five ways that leads to the formation of sedimentary rock?
Depositing, weathering, erosion, compacting, cementing
What is geologic exfoliation?
When a mass of rock is exposed by weathering and by removal of the overlying rock there is a decrease in the confining pressure on the rock, and a slight expansion of the rock volume. This unloading promotes cracking of the rock – known as exfoliation - and the development of cracks leads to other kinds of weathering.

How does chemical weathering speed up the effects of mechanical weathering?
Mechanical weathering breaks down the rock into smaller pieces, exposing more surface area. This allows the acid and chemicals to break down the pieces of rock faster.
How can physical weathering increase the rate of chemical weathering?
Physical weathering breaks rock down into much smaller pieces and gives the original rock a much greater surface area which, when exposed to chemical agents such as carbonic acid, reacts at a much faster rate than it would had the larger rock not undergone physical weathering.
What is caused by stress and the bending tiliting and breaking of rock?
Stress changes the shape or breaks (fractures) rocks whereas bending leads to folding
A rock will weather faster after it has been crushed because it?
The crushed rock pieces have a greater surface area then whole rock giving more exposure to weathering.
