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.
This region is most likely a part of the tundra biome. Tundra biomes can have the conditions that are listed such as low average temperatures year round, very little precipitation, and this region supports only small plants and a few animal species. Specifically plant life in Tundra regions are usually low to the ground with very few trees because of the flat area and the harsh winds that blow through these regions. This region is also most likely an arctic tundra due to the very low temperatures.
