What else can I help you with?
Ice wedging occurs because a given amount of ice has a volume?
Volume increase which exerts force.
What is another name for frost wedging?
Another name for frost wedging is ice wedging. This process occurs when water freezes in cracks and crevices in rocks, causing them to expand and eventually break apart.
What kind of weathering occurs fastest in cold wet climates?
frost wedging
Would ice wedging happen if water did not expand as it froze?
No, it would not. Wedging cannot occur if the solid form (ice) didn't occupy a greater volume than the liquid form.
How is frost wedging similar to root wedging?
they are both a type of physical weathering and both may break rock through a crack or a crevice. Frost wedging is when water enters a crack and may freeze causing the crack to expand because when water freezes it contrasts and expands. Root wedging is when a plant grows through a crack causing the roots to expand and break through the rock. -michael yap
What weathering occurs when rocks are broken apart by physical processes?
Mechanical weathering occurs when rocks are broken apart by physical processes such as frost wedging, root wedging, or abrasion. These processes break down rocks into smaller fragments without altering their chemical composition.
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.
What is the one type of frost action?
The one type of frost action is frost wedging, which occurs when water seeps into cracks in rocks, freezes, and expands, causing the rock to break apart.
Where does Ice wedging occurs?
This tends to be a polar or sub-polar effect, where a small crack becomes enlarged over time with thaw-freeze cycles.
What type of frost action occurs when a crack ina rock widens from the freezing and thawing of water?
ice wedging
This occurs when the need for moisture is greater than the amount of rainfall and the soil water supply is depleted?
A deficit of water, and a desert!
A greater amount of DNA damage occurs when a living organism is exposed to a greater amount of a radioactive isotope. How might this affect the number of mutations acquired by the organ?
Answer this question… More mutations will be acquired, leading to more phenotypic changes.
