Final answer:
Fragmentation of bedrock is the most obvious result of weathering, which breaks down rocks into smaller particles that may be transported and deposited elsewhere, shaping the Earth's surface.
Step-by-step explanation:
The most obvious result of weathering is B) Fragmentation of bedrock. Weathering occurs when physical and chemical processes break down rocks into smaller particles, resulting in various sizes of fragments like gravel, sand, and clay. This layer of disintegrated rock material can ultimately contribute to soil development. Furthermore, these fragments may be transported by natural forces such as water, leading to their deposition in new locations. This cycle of weathering and transportation is crucial in shaping Earth's surface features such as valleys, cliffs, and caves.
