Why marble is a impure substance?
The absolute purity doesn't exist; all the materials have impurities, less or more.
How does marble differ from limestone there than color?
Hardness, Elasticity, Porosity, Permeability, Density, resistance to diagenesis, conditions of formation. Generalities (this means that in general the following are true and rules don't follow the exception if any exist) Hardness: marble is harder than limestone. It has a higher compressive strength and cohesion. This can get much more technical so let's leave it at that. Elasticity: Young's Modulus, shear modulus of marble is higher. Bulk modulus and poisson's ratio of marble is lower. Porosity of marble is lower. Permeability of marble is lower. Density of marble is higher. Limestone is often altered via fluids and chemical underground and marble isn't. Marble is metamorphic rock and limestone in sedimentary. Marble and Limestone are spelled different.
What concerns exist about the mining and the processing of natural sources of uranium?
Disadvantages of uranium: 1. Uranium is a possible polluting agent of the natural environment. 2. Uranium is a toxic and a radioactive chemical element. 3. Uranium release radium and radon. 4. Radioactive wastes are dangerous and need to be isolated.
Why did the solar system exist?

Why is marble useful for carving chess pieces?

Are there any mining helmets in minecraft?

How much does a large marble weigh?
Marble is a type of rock and it exist in nature as a mountain or hill. There is no size limit for this answer. It can weight a few kg for construction marble cut to a few Gigaton of mountain rock.
Why does mining exist?
To supply people and industries with minerals, metal ores and coal, etc.
Why marble is a impure substance?
The absolute purity doesn't exist; all the materials have impurities, less or more.
Why aren't quarries dug everywhere in the UK?
Because not all areas have raw materials suitable for quarrying ! Many minerals exist in 'pockets' - some of which are confined to small areas.
Is uranium found in Greenland?
Yes, uranium exist in Greenland and is prospected now by an Australian mining company.
If there was no mining would the gold rush exist?
The gold rushes existed because gold was first found on the surface. Much of the gold was extracted by panning . Actual mining , digging deeper , came later.

Why opencast mining is cheaper for companies?
because opencast mining doesnt require shafts and tunnels to be built unlike other approaches such as deep mining. it is on the surface so transportation costs from underground to ground level do not exist. insurance costs for miners may be lower as there is no risk of the mine 'caving in'.
What is the Molarity of a solution made from dissolving 53.6grams of calcium carbonate in 0.94 liters of water?
It doesn't exist - calcium carbonate is limestone/marble - its insoluble
What is a possible danger of obtaining rock salt by mining?
Two problems exist: - Collapse of the mine roof - Flooding the mine and salt dissolution
