Which element is responsible for the red colour of red soil?
Iron
Red soil gets its characteristic colour from the presence of iron oxides that form when iron-bearing minerals in the parent rock undergo weathering under oxidising conditions.
These iron oxide compounds impart a reddish tint to the soil, distinguishing it from other soil types such as black or alluvial soil.
Calcium, copper, and magnesium are not the elements responsible for this characteristic red colouring.
