Question

This residue contains aeolian dust, volcanic material, or sedimentary clastic rocks transported in limestone and dolomite regions. What is being talked about here?

• A. Limestone caves
• B. Sink holes
• C. Non-porous rocks
• D. Red Soil

Answer 1

The correct option is D Red Soil

In some Karst regions, the dissolution of limestone, and deposition results in the formation of a special kind of red clay soil. This soil is known as Terra Rossa. The residue is composed of parent materials like aeolian dust, volcanic material, or sedimentary clastic rocks transported to these limestone and dolomite regions in the past. The soil develops its red colour due to the presence of iron oxide.
