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

When limestone is added to lakes why is it powdered?
Limestone is an alkali and will therefore react with the acid in the lake, thereby reducing the acidity.
How is lime mined?
Limestone may be mined in a surface quarry, typically by drilling, blasting, and crushing the shot rock. In some areas, limestone mines are underground. In Florida, some limestone mines are under water- the rock is drilled, shot, and mucked while under water. Limestone may be crushed to aggregate sizes, or finely crushed to a powder state for agricultural limestone, or used a "mine safety dust" to control methane and dust in coal mines. Powdered limestone (calcium carbonate) may be roasted and hydrated to form quicklime (Calcium oxide or calcium hydroxide)
What skin like surface is formed because of polar nature of water?
Surface Tension
What would be the long term effects of acid rain?
Acidic surface waters decrease the survivability of animal life in lakes and streams and in the more severe instances eliminate some or all types of fish and other organisms.
What is unique about surface reactions?
Surface reactions are considered unique because they are catalyzed by surfaces that will change the kinetics of a reaction.
What Regions of the earths surface where limestone is exposed and abundant are called?
Fluitary
Where can limestone caves befound?
generally, in limestone uplands, where the limestone is sufficiently massive to hold caves, and particularly but not exclusively where the local surface drainage can concentrate rainwater into discreet streams than can then form sink caves when they flow onto the limestone.
If limestone was crushed what would it do to the rate of reaction between an acid and the limestone?
If the limestone was crushed the reaction would speed up because the limestone would have a larger surface area available to react with the acid.
Why was sandstone used to build the cumbria bridge and not limestone?
limestone is not used in Columbia because crevices are present on its surface, while sand stone has porous surface which readily absorbs pollutants.
What percentage of Earth's surface is covered by limestone?
I think it is 75 % of the earths surface is covered by limestone
How is the Gibson Desert in Australia unique?
It is unique because of its treeless surface and its limestone geology
What region in Mexico has limestone?
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.
How are resurgent streams formed?
Resurgent Stream arise when the limestone is underlain by an impermeable rock, such as clay. this forces the water out into the open, forming a spring or resurgent stream.
Where do you get limestone?
Limestone can be found in many parts of the world and is usually mined in surface quarries.
Why did the Egyptians use sandstone to build pyramids?
1. It was available close to the pyramid site 2. Limestone is quite a soft stone so easy to work with copper tools
Why are limestone caves so common?
Limestone caves are common because limestone is a soluble rock that dissolves easily in water. Over time, groundwater flowing through cracks in the limestone gradually enlarges these passages to form caves. Additionally, limestone is often found in areas with karst topography, characterized by sinkholes, underground rivers, and other features that promote the formation of caves.
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.
