Sedimentary rock is formed through a process where particles from pre-existing rocks or biological remains accumulate, are compacted, and ultimately cemented together. This process typically occurs in layers, often in bodies of water, where sediments can settle over time. The compaction occurs when the weight of additional sediments above applies pressure to the lower layers, while cementation involves minerals precipitating from water and filling the spaces between the particles, binding them together.

Igneous rock, on the other hand, forms from the cooling and solidification of molten material (magma or lava), which is a different process than the one described in the question. Metamorphic rock arises from the alteration of existing rock types under heat and pressure but does not form from sediment accumulation. Basalt is a specific type of igneous rock that is formed from the rapid cooling of lava at the earth's surface and therefore does not fit the criteria for the type of rock in question. Thus, sedimentary rock is the correct answer as it directly relates to the process described.
