d) The oldest streams within the drainage basin

Answer 1

Bedrock streams are those that are actively cutting into the bedrock of an area, often shaping the landscape by creating features like canyons or gorges.

Step-by-step explanation:

Bedrock streams are streams that are cutting into the bedrock of the area. These streams actively erode their channels into the underlying geological layers, which can consist of various types of rock, such as limestone, shale, or granite.

As bedrock streams cut into the bedrock, they often create distinctive features in the landscape, like canyons or gorges, and contribute to shaping the topography. Bedrock streams are different from other types of streams that may have channels lined with sediments or be integral parts of their local ecosystems without necessarily cutting into the bedrock.
