Final answer:
Shield areas in continental interiors are characterized by ancient, stable, and exposed bedrock.
Step-by-step explanation:
Shield areas in continental interiors are characterized by ancient, stable, and exposed bedrock. These regions are made up of the Earth's oldest rocks, which have been heavily eroded over time, resulting in a relatively flat landscape with few mountains or valleys. Examples of shield areas include the Canadian Shield in North America and the Fennoscandian Shield in Northern Europe.
