Answer: Option B
Solution
Answer: Option B
Solution:
Entisols are the young soils with no horizon. These are the most abundant soil order, occupying about 16% of the global ice-free land area.Vertisols are clay-rich soil. The high content of clay minerals shrinks and swells as they change water content.
Spodosols are acid soils with the leached upper horizon and are characterized by an accumulation of humus that is complexed with aluminium and Iron.
Oxisol is highly weathered tropical and subtropical soil. These are found primarily in the intertropical regions of the world.
