Give reason: [3]

ii) wind is common agent of soil erosion in arid regions.

iii) terrace farming is an ideal soil conservation method for hilly regions. ​

Answer 1

Answer:

a. i. Alluvial Soil

⠀ii. Red Soil

b. i. Regions that receive less than 75 cm of rainfall are suitable for dry farming. Red soil is porous so does not retain moisture. So, dry farming is preferred in areas of dry farming.

ii. Arid regions are extensively flat lands with no or few vegetation cover. So, the dry ends are able to erode the upper surface soil surface which become loose due to absence of obstruction.

iii. Terraced farming checks erosion as it controls the direct flow of water down the slopes.
