Which statement is true regarding geologic features on Earth?

The statement about continents having elevated areas called plateaus is true. Plateaus are significant geological features that rise sharply above the surrounding area and are characterized by flat terrain. They can be formed through various geological processes, including volcanic activity, erosion of land, and the uplift of the Earth's crust due to tectonic forces. These elevated regions can cover extensive areas and are often found on continents, demonstrating the varied topography of Earth's surface.

In contrast, mid-ocean ridges are not limited to the Atlantic Ocean; they are found in all major oceans, making option A inaccurate. Seamounts, which are underwater mountains, can indeed contribute to the formation of island arcs, especially in subduction zone settings, rendering option B wrong. Lastly, abyssal plains are not mountainous regions but rather expansive, flat areas of the ocean floor, typically found at great depths, which contradicts option D. Thus, the true and accurate statement pertains to the presence of plateaus on continents.
