The process of Podsolization is predominantly found in:
Taiga forest
Podzolisation (also spelt Podsolisation) is a soil-forming process characteristic of cold, humid coniferous (taiga/boreal) forests. Slow decomposition of needle-leaf litter produces strongly acidic humus. Percolating rain leaches iron, aluminium and organic matter from the upper (A/E) horizons and redeposits them in the B horizon, forming the distinctive ashy-grey E horizon that gives Podzols their name (Russian pod zola = 'under the ash').
Correct answer: Taiga forest.
Which of the following statements regarding Barchan is/are correct?

2. The windward side has a convex steep slope with maximum height at the centre.
3. Two ends of Barchan are called horns and point opposite to the direction the wind blows.
