Explanation by: Admin

Terra Rossa is a type of red soil that typically forms in karst (limestone) regions through the process of chemical weathering.

  • It develops when limestone dissolves due to carbonic acid in rainwater, leaving behind insoluble red clay residues rich in iron oxides, which give the soil its reddish color.

Key Features:

  • Found in Mediterranean climates.
  • Fertile and good for agriculture like viticulture (grape growing).

Why other options are incorrect:

  • (B) Granite – Leads to sandy, acidic soils, not Terra Rossa.
  • (C) Syenite – Similar to granite but poor in quartz; does not produce Terra Rossa.
  • (D) Red sandstone – Weathers into loamy or sandy soils, not Terra Rossa.

Hence, Terra Rossa is most closely associated with (A) Limestone terrains.
