Does the rate of chemical weathering increase or stay the same when the rocks becomes more mechanically weathered?
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
What are two ways rocks are mechanically weathered?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
Why is chemical weathering common in places where there are large amounts of limestone and water?
Rainwater is naturally slightly acidic. The acid in rainwater reacts chemically with the calcium carbonate of limestone, dissolving it. The result is chemically weathered limestone, karst terrains, and cave structures.
What is the Basal surface of weathering?
Basal Surface of Weathering is also known as the Weathering Front, which is the boundary between weathered and unweathered rocks.
When granite is chemically weathered what happens?
it is changed to a clay form
If two identical rocks were weathered one mechnically and the other chemically how would the products of weathering for the two rocks differ?
The product of the mechanically weathered rock would be identical to the original rock. The product of the chemically weathered rock would be dissimilar to the original rock.
Are sedimentary rocks chemically weathered?
Sedimentary rocks can be both chemically and mechanically weathered.
Does the rate of chemical weathering increase or stay the same when the rocks becomes more mechanically weathered?
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
Does the rate of chemical weathering increase or stay the same when a rock becomes more mechanical weathered?
The rate of chemical weathering increases when a rock becomes more mechanically weathered, also called abrasion.
Which is best at weathering rocks?
Most surface rock is weathered by water. Naturally acidic rain and groundwater can react chemically with rock, causing dissolution and oxidation. Freezing water can also act on the rock mechanically, forcing open gaps and faults for further weathering attack by liquid water.
When rocks become reddish brown in color they have been chemically weathered through the process called?
The Weathering Cycle.
Does the rate at which a rock undergoes chemical weathering increase or stay the same when the rock becomes more mechanically weathered why?
The rate will increase due to the increase in surface area available for attack by chemical weathering.
What are two ways rocks are mechanically weathered?
Two forms of mechanical weathering are frost heaving and plant root wedging. All forms of mechanical weathering result in the breakage of rock into smaller size particles.
Is granite chemically weathered?
yep
How rocks are mechanically weathered.?
Frost Wedging hiya kids!=)

What is a karst terrain?
It is an area of exposed, mechanically and chemically weathered and eroded limestone landscape terrain and may contain sinkholes, caves, and other features. See the link below for pictures of an extreme karst terrain.
