Question

Quizplus · Accepted Answer

The continental platform, or continental shelf, is characterized by nearly horizontal sedimentary rocks that have been deposited on top of older, crystalline basement rocks. This description accurately reflects the geological features found within continental interiors. Shields are indeed old, stable, crystalline rock formations, but they are not described as basaltic volcanoes. The oldest exposed rocks are typically found in the interior parts of continents, such as in shields, rather than along coastlines. Broad domes and basins may have deformed beds, but they are not typically described as having nearly vertical beds around their flanks.
