Melting ice significantly contributes to the supply of sediments in oceans, making the chosen answer valid. When ice sheets and glaciers melt, they release not only freshwater but also a variety of materials that have been trapped or stored within the ice, including rocks, minerals, and organic matter. This process effectively increases the amount of sediment entering the ocean, as these materials are washed away by melting ice and carried into the surrounding waters.

As a result, the melt contributes to enhanced sediment supply in areas that may have previously been starved of such materials. Increased sediment supply can impact marine ecosystems, coastal processes, and even global carbon cycles, as sediments play a fundamental role in ocean health and climate regulation. This distinction highlights the dynamic interplay between ice melt and sediment dynamics in marine environments.
