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.
d. continuous urban development connected by transportation routes.
It is a false statement that an occluded fronts is characterized as the beginning stages of a middle latitude cyclone.
<h3>What is a middle latitude cyclone?</h3>
It refers to the synoptic scale low pressure system that has cyclonic flow that is found in the middle latitudes in a counter-clockwise form in northern hemisphere.
Most time, what occurs during the occluded front phase of a middle latitude cyclone is that there is a dryness and coolness of the air that causing a dissipation of the system.
Therefore, It is a false statement that an occluded fronts is characterized as the beginning stages of a middle latitude cyclone.
