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.
What are limestone pillars?
Limestone pillars are natural rock formations that are tall, narrow structures made of limestone. They are typically found in areas where erosion has worn away softer rock surrounding the limestone, leaving behind these distinctive pillars. Examples of limestone pillars can be found in places like caves, coastlines, and karst landscapes.
What are rocks that have been worn away or broken up by chemical biological or physical processes called?
Rocks that have been worn away or broken up by chemical, biological, or physical processes are called "sedimentary rocks." These processes, known as weathering and erosion, lead to the breakdown of pre-existing rocks into smaller particles, which can then accumulate and eventually lithify into sedimentary formations. Examples of sedimentary rocks include sandstone, limestone, and shale.
What could take a layer of limestone away from a fossil?
If the fossil is replaced with silica the easiest way to remove the limestone is with weak acid such as vinegar. If the fossil is also limestone the best way to free it is by carefully removing the limestone with small picks and drills. This is usually best left to expert conservators as it can be delicate work.
What forms when limestone found in the earth has been eatin away?
When limestone is eaten away, it forms various features such as sinkholes, caves, and underground tunnels. This process occurs due to the dissolution of the limestone by acidic groundwater. The result is the creation of unique and sometimes expansive underground landscapes.
What did they use to build the pyramids of egypt?
Limestone, but is has mostly worn away because of the elements.

Does acid rain have affect in sandstone?
yes it does ,the surface is worn away because there is a reaction between the sandstone and limestone.
Why is limestone not used for buildings?
Because it is a permiable rock, this means it will be worn away over time. Although it does still get used for buildings
What is a fact about waterfalls?
Sometimes, a waterfall when a river flows from hard rock to softer rock. The softer rock, such as limestone, is easily eroded, or worn away, by the flow of the river.
What type of rock is worn away by weak acid in water to create a cave?
Limestone is the type of rock that is commonly dissolved by weak acids in water, such as carbonic acid, to form caves through a process known as chemical weathering.
What is the chemical that can wear away limestone?
H2O Yes water is a chemical and it can wear away limestone.
Why are the twelve apostles in Victoria Australia collapsing?
Water is one of the most effective substances at eroding away material, particularly when it is a relatively soft substance like limestone. The "Twelve Apostles" are made of soft and harder limestone, and the softer limestone has worn away over time. The constant action of the waves beating at the limestone pillars of the Twelve Apostles, over time, has resulted in weakening of the thinner foundations at the waterline. The weight above the waterline is sufficient to cause the collapse.
What are limestone pillars?

They are typically found in areas where erosion has worn away softer rock surrounding the limestone, leaving behind these distinctive pillars.

What does acid rain make house's from limestone do?
acid rain decomposes limestone (calcium carbonate), causing houses and buildings made out of them to become worn
How is limestone connected with hill sheep farming?
