Which location will experience the greatest amount of weathering

Explanation:

Weathering occurs fastest in hot, wet climates. It occurs very slowly in hot and dry climates.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
