B) Cold and Dry. Chemical weathering generally occurs more rapidly in hot and wet climates, where moisture and higher temperatures promote chemical reactions. In cold and dry climates, the lack of moisture and lower temperatures slow down chemical reactions and thus result in slower chemical weathering.
28) B) It stays the same. When an object is broken into smaller pieces, the total volume of the object remains the same. The volume of an object is a measure of the space it occupies, and breaking it into smaller pieces does not change the amount of space it occupies.
