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.

Under what conditions is limestone formed?
Many living things, including coral, clams, oysters, and snails, have shells or skeletons made of calcite. When these animals die, their shells pile up a sediment on the ocean floor. Over millions of years, these layers of sediment can grow to a depth of hundreds of meters. Slowly, the pressure of waveringly layers compacts the sediment .Some of the shells dissolve, forming a solution of calcite that seeps into the spaces between the shell fragments. Later, the dissolved material comes out of solution, forming calcite. The calcite cements the shell particles together, forming limestone.
How many steps are there to create a clastic sedimentary rock?
# Weathering--the physical or chemical breakdown of rock into smaller particles. # Erosion--occurs when water, wind, ice, or gravity transport the rock particles. # Deposition-- the process by which sediment settles out of the water, wind, or ice carrying it. # Compaction- the process that presses sediments together, squeezing out air and fluids from spaces between particles. # Cementation- the process in which dissolved minerals crystalize and glue particles of sediment together. Note: it takes millions of years for compaction and cementation to transform loose sediments into solid sedimentary rock
What is the definition for a divergent boundary?
It is where 2 plates are separating, moving away from each other and magma fills the space.
How does fossil fuel affect limestone?
The question is a little difficult to answer because the way it is worded. Fossil fuels are hydrocarbons (oil and gas), and coal. Hydrocarbons result after organic materials are confined underground for very long periods of time under the right conditions of pressure and temperature. Generally, hydrocarbons are found in sandstones and carbonates. The carbonates may be complex mixtures, but are generally reservoir carbonate rocks are classified as consisting primarily of dolomites or limestones. There are changes in the limestone structure as a result of the decomposition of organic material, but these changes are more the result of water which may contain other salts and other minerals that water contains. Water is responsible for the transport of clays or silts into the pore structure. The pores of the limestone may become larger due to the dissolving of calcium by the water or the substitution of calcium for magnesium, which is called dolomitization. Clays can form in the pore spaces and restrict flow. .
What is the movement of surface water into rocks or soil through cracks or pore spaces?
Infiltration is the movement of surface water into rocks or soil through cracks or pore spaces.
How does water in the spaces of a limestone cause physical weathering of the limestone?
Water in the spaces of limestone can cause physical weathering through a process called freeze-thaw. When water seeps into the cracks and pores of the limestone, it freezes and expands upon freezing, exerting pressure on the surrounding rock. This expansion and contraction cycle weakens the limestone, causing it to crack and break apart over time.
How can chemical wethering form a cavern?
Chemical weathering can form a cavern by infiltrating pore spaces in limestone.
What is the large underground opening formed by weathering and erosion?
cavern Answer #2: A sinkhole.cavern
How does acid and rain water affect the land underground?
Acid in the rainwater causes limestone to dissolve, leaving open spaces, or caves.
Are you at fault if you pull through end to end parking spaces and a person entering the space from the travel lane collides with you?
no!
What type of building foundations were used to build the Rockefeller Center?
Rockefeller Center Complex of 14 limestone skyscrapers set amid a series of outdoor spaces on a 12-acre (5-hectare) site, built between 1929 and 1
What is a Clint and grike in topography?
A Limestone pavement is made up of two separate but important parts known as clints and grykes,Clints are the blocks of limestone that forms the paving, their area and shape is directly reliant upon the occurrence and pattern of grykes, Grykes are the spaces that separate the individual clints.
Cell references in formulas must be entered in uppercase and spaces cannot be added before or after arithmetic operators?
Formulas can be entered in any case, but after entering them they will convert to uppercase. Spaces can also be entered with no problems, and the formulas will still work.

Why is plastic foam good at reducing heat loss?
It fills in spaces where air can penetrate and your conditioned air can escape. It is also great for keeping insects from entering your home.
Why does permeable weather chemically at a fast rate?
It is because the rock is full of tiny air spaces that allow water to seep through it, so as the water seeps through the spaces it dissolves and removes material broken down by weathering. If you are doing this for a school science question, that's what textbooks are for. If not, then I can tell you are a person who enjoys to read and is a scientist.
