Question

select the correct answer.
the statue of leshan giant buddha in sichuan, china, is carved directly into the mountainside. the color and texture of the statue are constantly changing due to the pollutants from vehicles and industries nearby. what are the two main causes of the changes to the statue?

a. wind and rainfall
b. rainfall and chemical reaction
c. rainfall and gravity
d. gravity and wind
e. wind and chemical reaction

Explanation:

The Leshan Giant Buddha's changes are due to pollutants. Wind can carry pollutants (like dust, acidic particles) to the statue, and chemical reactions (e.g., acid rain from pollutants reacting with water in rain, or oxidation from pollutants) alter its color/texture. Rainfall alone (without chemical reactions from pollutants) or gravity/wind (gravity isn't a main cause here) don't explain. Option E (wind and chemical reaction) fits: wind transports pollutants, chemical reactions (from pollutants) change the statue.

Answer:

E. wind and chemical reaction
