When an igneous rock is eroded and then deposited at the bottom of an ocean, it becomes which type of rock?

Explanation:
Weathering and erosion break rocks into sediments, which then settle and are turned into rock through lithification (compaction and cementation) in a depositional environment like the ocean floor. Since the rock started as igneous but has been broken down and reassembled as sediment, the resulting rock is sedimentary. It isn’t igneous because cooling isn’t involved, and it isn’t metamorphic because there hasn’t been the heat or pressure needed to change its mineral structure; if anything specific is considered, it would be a clastic type of sedimentary rock, formed from fragmented pieces.
