A geologist looks at a map to determine which of two areas would experience more chemical weathering. Area 1 is on the coast of a country in South America, near the equator. The temperatures are hot, and the climate is humid with heavy rainfall. Area 2 is in the Midwestern United States. The temperature is relatively cool, and the climate does not include much humidity or rainfall. Based on the given information, which area is most likely to have more chemical weathering?
