Answer: Sediments
The interaction of igneous rock with wind and water over a long period of time will result in withering of rock. Withering is a natural process, which brings alteration to the structure and composition of rock, when the rock is exposed to agents like air, water and organic fluids. The eroded material from igneous rock will get settled place other than the one where parent rock existed. This eroded material is called as sediment.
Therefore, the interaction of igneous rock with wind and water over a long period of time will form sediments.
