D. Cold and wet.

1 answer

The fastest chemical weathering of granite, sandstone, and shale will occur under conditions that promote chemical reactions, which are typically enhanced by warmth and moisture. Among the options given, the ideal conditions for rapid chemical weathering would be:

B. Warm and wet.

Warm temperatures increase the rates of chemical reactions, and ample moisture facilitates the reactions by providing the necessary water for processes such as hydrolysis and dissolution.
