Social Studies BJC Set 2 Practice Test

Soil color shows what the ground is made of and how much weathering it has undergone in a tropical climate. Red soil forms when iron-rich minerals in the rock oxidize and create a reddish clay over time, a pattern that can develop where limestone bedrock is weathered in warm, wet conditions. The Bahamas are largely built on coral limestone and have many light, sandy soils, but Eleuthera has inland areas where this weathering produces a noticeable reddish clay layer, giving red soil its distinctive color. The other islands you mentioned are more associated with lighter sands or different soil types (for example, Nassau and Grand Bahama with light beach sands, and Andros with peat- and mangrove-influenced soils), so red soil is best linked to Eleuthera.
