Explanation:
(a)
There is inverse relation between concentration of aluminium and pH value and it can lead to aluminium toxicity. In this case it will dominate in the form of Hydroxy- aluminium, Al³⁺ cation and polynuclear species.
(b)
Various minerals are brought to the soil during its formation . As we know the pedogenesis process starts due to erosion of the rocks and rocks contain various minerals, of which aluminium is also a part. With time, aluminium gets dissolved in water and the soil and as the rocks become soil after going through various processes like traction, solution etc, it gets aluminium ions also with it.

Answer:
A Mercator map projection greatly distorts the area of land masses near the poles.
Explanation:
Mercator projection is a projection method where the meridians are deposited vertically on the parallel circles, and where the distance along these circles is gradually stretched more in relation to the terrain it gets closer to the pole. The method is common, for example on world and sea maps. It maintains directions correctly.
The projection gets right at the equator but in theory never reaches the poles and it depends on the cylindrical projection. Gerhardus Mercator's projection became famous in the 16th century and has since been used on the seas.
Answer: Since the base of a cylinder is a circle, we substitute 2πr for p and πr2 for B where r is the radius of the base of the cylinder.
