mechanical weathering process in which outer rock layers are stripped away, often resulting in dome - shaped formations
exfoliation
frost wedging
pitch scarring
chemical weathering

Explanation:

To solve this, we analyze each option:

• Exfoliation: A mechanical weathering process where outer rock layers peel off, forming dome - like structures. This matches the description.
• Frost wedging: Involves water freezing and expanding in rock cracks, breaking rocks, not related to outer layers stripping for domes.
• Pitch scarring: Not a recognized weathering process related to this description.
• Chemical weathering: Involves chemical reactions altering rock composition, not mechanical stripping of layers.

Answer:

A. exfoliation
