Verified
Because shales and siltstones are easily eroded, the areas where they are exposed typically:
A) have soft slopes and soil cover
B) are covered in angular boulders and cobbles
C) form steep cliffs
Shales
Fine-grained sedimentary rocks that can split into thin, parallel layers, composed mainly of clay minerals.
Siltstones
Fine-grained sedimentary rocks that consist predominantly of silt particles, smaller than sand grains but larger than clay, often formed in quiet water environments.

Final Answer :
A
Explanation :
Shales and siltstones are easily eroded due to their fine-grained nature, leading to the formation of softer slopes and soil cover rather than steep cliffs or areas covered in angular boulders and cobbles.
