Is frost wedging related to chemical weathering?
No, frost wedging is a physical weathering process caused by the expansion of freezing water in cracks and crevices of rocks. Chemical weathering involves the breakdown of rocks through chemical reactions rather than physical forces like frost.
Is water seeping into the cracks of rocks and freezing an example of physical weathering?
Yes, as the water freezes it expands and cracks the rock a little bit more pushing off pieces. This is a process of mechanical / physical weathering- called 'frost wedging' or 'freeze thaw'.
When a boulder cracks in half because water freezes and thaws over time. What process has occurred is it chemical or physical weathering?
The process that occurs when a boulder cracks due to water freezing and thawing over time is physical weathering. This is because the mechanical force of the expanding ice causes the rock to break apart, without involving any chemical reactions.
Which is an agent of physical weathering?
Frost is an agent of physical weathering. When water freezes in cracks in rocks, it expands and exerts pressure on the surrounding rock, causing it to break apart.
Is ice wedging physical weathering or chemical weathering?
Ice wedging is physical weathering. As water freezes it grows, so when water flows into cracks or holes and then freezes it causes the water to expand, which brakes apart whatever it seeped into.
How does physical weathering make the job easier for chemical weathering?
Physical weathering, such as cracks, creates more surface area for chemical weathering to occur on.
Is water freezing in cracks in a rock a physical weathering?
Yes, water freezing in cracks in a rock is a form of physical weathering called frost wedging. As water freezes, it expands, putting pressure on the rock and causing it to break apart over time.
Is frost wedging related to chemical weathering?
No, frost wedging is a physical weathering process caused by the expansion of freezing water in cracks and crevices of rocks. Chemical weathering involves the breakdown of rocks through chemical reactions rather than physical forces like frost.
How do cracks get wider in limestone?
Cracks in limestone can widen due to a combination of factors, such as physical weathering from water freezing and thawing, chemical weathering from acidic rainwater, and biological weathering from roots growing and expanding within the cracks. Over time, this continuous process of erosion can cause the cracks to widen significantly.
Which one of the following is a source of chemical weathering a The abrasion of running water b Water freezing in the cracks of exposed rocks?
b. water freezing in the cracks of exposed rocks
Is water seeping into the cracks of rocks and freezing an example of physical weathering?
Yes, as the water freezes it expands and cracks the rock a little bit more pushing off pieces. This is a process of mechanical / physical weathering- called 'frost wedging' or 'freeze thaw'.
Is freezing and thawing classified as chemical weathering or mechanical weathering?
Freezing and thawing is classified as a type of mechanical weathering, specifically known as frost wedging. This process occurs when water seeps into cracks in rocks, freezes and expands, causing the rock to break apart over time.
When a boulder cracks in half because water freezes and thaws over time. What process has occurred is it chemical or physical weathering?
The process that occurs when a boulder cracks due to water freezing and thawing over time is physical weathering. This is because the mechanical force of the expanding ice causes the rock to break apart, without involving any chemical reactions.
Is water freezing in the cracks of exposed rocks a source chemical weathering?
No. Chemical weathering is only when acid rain etc. is involved. I suppose you could call this 'natural weathering' but I'm not sure that is the correct term because it is simply water freezing and expanding.
Which is an agent of physical weathering?
Frost is an agent of physical weathering. When water freezes in cracks in rocks, it expands and exerts pressure on the surrounding rock, causing it to break apart.
Is ice wedging physical weathering or chemical weathering?
Ice wedging is physical weathering. As water freezes it grows, so when water flows into cracks or holes and then freezes it causes the water to expand, which brakes apart whatever it seeped into.
How does physical weathering cause chemical weathering to be more effective?
by helping each other by breaking down the minerals
