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.

What river forms a large portion of the border between the United states and Mexico?
The Rio Grande River forms a large portion of the border between the United States and Mexico. The Rio Grande River is a global river that separates Mexico and the United States. It starts from Colorado, and then dribbles till Gulf of Mexico.
Hope I helped :D
Answer:
Geomorphological processes and resultant topography are related with glacial, aeolian, fluvial and ground water movement.
- Outwash plain: <em>deposited mostly by water from melting glaciers.</em>
- Sand dunes: <em>not related to glaciation</em>
- Offshore bar: <em>not related to glaciation</em>
- Moraine: <em>deposited by glaciers</em>
Explanation:
Each and every geomorphological process has three types work. For e.g. erosional work, transportational work and depositional work.
- Outwash plain produced by fluvio-glacial depositional work where firstly glaciers melt and then the water flows and deposits sediments in a flat area.
- Moraine produced by glacial deposition. Glaciers carry sediments (pebbles, cobbles) and when it deposits in the valley floor it results a distinguished landform i.e. moraine.
- Sand dunes produced by aeolian action (depositional work). When wind receives obstacle in the form of tree or stone in its way it deposits sand in desert area and produce sand dunes.
- Offshore bar produced by marine processes. when sediments deposited in the coastal area in a huge quantity and friction take place between the wave and sea floor it creates offshore bar.
