When limestone is exposed to air for two days, it can undergo a chemical reaction with carbon dioxide in the air to form calcium carbonate, which may result in weathering or erosion of the limestone surface. This process is known as carbonation and can lead to the formation of cracks or pits on the limestone surface over time.
Probably about 80%. This is what I have heard and learnt.
Limestone pavement is formed through a combination of weathering and erosion processes acting on the surface of limestone rock. This typically involves the dissolution of calcium carbonate in the limestone by rainwater, which creates fissures and cracks on the surface. Over time, these fissures widen and deepen, resulting in the characteristic large, flat slabs of rock separated by deep grooves that are typical of limestone pavement landscapes.
Limestone pavement can be found in a large number of places, however one famous example is Malham Cove in North Yorkshire in the United Kingdom. Please see the related link for more information and a photograph of the Limestone Pavement at Malham.
The Earth's surface is made up of various types of rocks, primarily igneous, sedimentary, and metamorphic rocks. The most abundant rock type is basalt, which makes up the oceanic crust, while granite is common in continental crust. Additionally, sedimentary rocks like sandstone and limestone are also found on the Earth's surface.

Shale, sandstone, limestone, basalt, and granite are fairly commonly exposed on the surface of the Earth.
Regions overlying limestone bedrock tend to have fewer visible groundwater sources (such as streams & ponds), since surface water easily drains downward through permeable fractures and fissures in the limestone

Crushing limestone would increase the surface area available for the acid to react with, thus increasing the rate of reaction between the acid and the limestone. This is because more particles of limestone would be exposed, allowing for more frequent collisions with the acid molecules.

I think it is 75 % of the earths surface is covered by limestone
The surface areas of the ocean have abundant nutrients.
Several regions throughout Mexico have considerable deposits of limestone, but the Yucatan Peninsula is the largest of them all, being mostly a flat land composed of limestone. Due to this nature, there are almost no surface rivers in the peninsula and most water comes from holes in the ground known as cenotes.
No. Over 75% of earths surface is covered with these rocks, but it is only a thin layer. Actually, only 5% of earth's inner crust is made up of it.

Limestone can be found in many parts of the world and is usually mined in surface quarries.
