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.
Mars' atmosphere is made mostly of carbon dioxide, much like Venus. It is not as hot as Venus because the Martian atmosphere is extremely thin. Venus has a thick layer of carbon dioxide gas surrounding the planet. This is why it is the hottest planet in the solar system even though it is not the closest to the sun. Carbon dioxide is a greenhouse gas so it has the ability to trap infrared radiation. The atmosphere on Mars is thin and so it will not trap as much heat as the Venusian atmosphere.
