What else can I help you with?
Is water a cause of physical weathering or chemical weathering?
It is a cause of both.
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.
How is limestone worn away?
Limestone can be worn away through a process called chemical weathering, where rainwater and acidic pollutants cause the rock to dissolve slowly over time. Physical weathering, such as freeze-thaw cycles and abrasion by wind and water, can also erode limestone by breaking it into smaller pieces. These processes combine to create features like caves, sinkholes, and cliffs in limestone landscapes.
How does physical weathering cause chemical weathering to be more effective?
by helping each other by breaking down the minerals
How does limestone affect monuments?
Limestone is primarily made of Calcium Carbonate which is a soluable in water and weak acid solutions. Anytime rainfall hits a monument made of limestone, it weathers it a bit faster than if it were made of marble.
How does water entering spaces in limestone cause physical weathering?
Mainly through expansion of cracks and fissures from frost expansion which leads to further and deeper cracks and fissures. Plant roots seeking moisture may extend roots into limestone cracks and fissures, prying the rock apart.

How is chemical weathering effect marble and limestone?
Chemical weathering can dissolve the calcite in marble and limestone over time, especially in the presence of acidic rain or groundwater. This can cause the rocks to deteriorate, forming cracks and pits on their surface. The dissolution of calcite can also weaken the structure of the rocks, leading to physical weathering processes like erosion.
What can cause physical weathering?
nothing
Is ice a cause of physical weathering?
no
What of these does not cause physical weathering?
Chemical weathering does not cause physical weathering. Chemical weathering refers to the breakdown of rocks through chemical reactions, while physical weathering is the process of breaking down rocks into smaller pieces without changing their chemical composition.

How does limestone break?
Limestone can break through physical weathering processes such as freeze-thaw cycles, which cause the rock to expand and contract, leading to cracks and eventual breakage. It can also break through chemical weathering, where exposure to acidic rainwater or groundwater can dissolve the minerals binding the limestone together. Additionally, biological weathering by plant roots or burrowing animals can contribute to the breakdown of limestone.
Can earthworms cause physical weathering?
not really.
Which is a cause of mechanical weathering?
physical forces
How can pocket gophers cause physical weathering?
By digging deep holes in the ground and breaking up rocks.
