A is a limestone pavement which is formed when the joints in the limestone are dissolved away by the rainwater. Limestone is dissolved because rainwater is a weak carbonic acid. The joints which are widened and deepened by this chemical weathering are called grikes. The blocks which stick up are called clints.

What is limestone swallow hole? What is a swallow hole? A swallow hole is a place where a stream or river disappears underground into limestone rock.
also How was Malham Cove formed? Malham Cove is a curved crag of carboniferous limestone formed after the last ice age. Meltwater, particularly from Malham Tarn, cut back the cove as it fell over the edge as a waterfall. This erosion took place more actively at the lip of the fall, hence the curved shape.
What are the cracks in limestone called?
Limestone is a sedimentary rock that is made up of horizontal blocks called bedding planes and vertical cracks called joints . Limestone is also a permeable rock which means that water can pass through its joints and cracks.
Where is the limestone pavement? Limestone pavements can be found in many previously-glaciated limestone environments around the world. Notable examples are found in the Yorkshire Dales and Cumbria in Northern England, such as those above Malham Cove, on the side of Ingleborough, and above Grange-over-Sands.
What is the difference between sinkhole and swallow hole?
A sinkhole, also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline (the different terms for sinkholes are often used interchangeably), is a depression or hole in the ground caused by some form of collapse of the surface layer. … Sinkholes may form gradually or suddenly, and are found worldwide.
Is limestone soluble? Limestone is partially soluble, especially in acid, and therefore forms many erosional landforms.
What are limestone uses?
Limestone is a source of lime (calcium oxide), which is used in steel manufacturing, mining, paper production, water treatment and purification, and plastic production. Lime also has major applications in the manufacture of glass and in agriculture.

What is limestone pavement made from? Limestone pavements
Rainwater is a weak carbonic acid which reacts with the limestone dissolving the stone, enlarging joints and bedding planes. … This leaves exposed blocks of limestone called clints and the resulting pattern of blocky rock is called a limestone pavement, eg Malham Cove.
What’s at the bottom of a sinkhole? Occasionally a sinkhole may exhibit a visible opening into a cave below. … Sinkholes are common where the rock below the land surface is limestone or other carbonate rock, salt beds, or in other soluble rocks, such as gypsum, that can be dissolved naturally by circulating ground water.
Which state has the most sinkholes in the United States?
The most damage from sinkholes tends to occur in Florida, Texas, Alabama, Missouri, Kentucky, Tennessee, and Pennsylvania.
What happens if you fall into a sinkhole? Take a look outside as well. When a sinkhole forms, water will start pooling on the ground. Trees and fence posts will start to tilt or fall over. The vegetation might wilt and die due to the sinkhole draining away water.
Does limestone absorb water?
Limestone is extremely durable. It does, however, absorb water and, since it is a carbonate rock, it is highly reactive when exposed to acids or even mildly acidic rain water, and it can suffer substantial deterioration. The most common effect of weathering and erosion is loss of precise detail.
What is marble used for? In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material.
