Final answer:
The seafloor landscape is best described as containing diverse features such as ridges, trenches, seamounts, and bed forms, shaped by tectonic and sedimentary processes.
Step-by-step explanation:
The landscape of the seafloor is best described as (d) containing ridges, trenches, seamounts, and other features different from those found on land. The seafloor is not a featureless plain, but instead is a dynamic and complex environment. Features such as trenches are associated with convergent plate boundaries and can be very deep and long, creating significant topographic depressions. The bed forms of the seafloor are also influenced by currents and waves, leading to a variety of undulating surfaces including ripples and sand ridges. Additionally, the geology of the seafloor involves volcanic rock compositions and the presence of both deep-water sediments like shales and sedimentary rock layers. These layers can be flat and parallel in calm areas, or disrupted and deformed in regions of tectonic activity. Deep-sea features like basins are characterized by their dipped strata that collect thick accumulations of sediment. Collectively, these aspects highlight the diversity and variance of subaquatic geology and topography.
