Minerals like tin and gold are sometimes mixed with _______ in the river bed.
The correct option is C Alluvium
The alluvium is the substance deposit
by a river. It is generally most widely developed in the subordinate element of
the course of a river, forming
floodplains and deltas, but may be deposited at any point where the river overflow
its bank or where the speed of a river is check—for example, where it runs into
a lake.
Alluvium consists
of deposit, polish, soil, and gravel and
normally contains a good deal of organic matter. It as a result yields very
fertile soils such as those of the deltas of the Mississippi, the Nile, the
Ganges and Brahmaputra, and the Huang rivers. In a quantity of region, alluvial
deposits contain gold, platinum, or gemstones and the superior part of the world’s
supply of tin ore.
Thus, the correct option is C.
