Which of the following is true about how weathering affects fractured rocks?

A) Weathering affects rocks from the outside in, forming an outer weathered zone or rind.
B) Weathering attacks corners from three sides and so these are preferentially removed.
C) Preferential weathering along fractures can cause blocks to become rounded.
D) D. All of these.

Outer Weathered Zone

The top layer of the Earth's surface, altered by weathering processes, involving the physical and chemical breakdown of rocks and minerals.

Fractured Rocks

Rocks that have been broken or cracked through natural processes or human activity, often creating pathways for the movement of fluids or gases.

Preferential Weathering

The process where certain materials in rocks weather at different rates due to variations in properties like composition and hardness.
