Which deposits occur in sands of valley floors and the base of hills?
Alluvial Deposits
Alluvial deposits are sediments laid down by flowing water — rivers deposit silt, sand and gravel on valley floors and at the foot of hills where the gradient suddenly decreases. These loose, fertile deposits are what give the Indo-Gangetic plain its agricultural richness and are typical of river-valley and piedmont environments.
Manganese and iron-ore deposits are formed by weathering and sedimentary/metamorphic processes in rocky terrain, and 'non-ferrous deposits' is a mineral classification, not a landform.
Hence, Alluvial Deposits.
