Thornthwaite's modified climatic classification is based on the concept of :

• Effective temperature

• Precipitation index

• Potential evapotranspiration

• Potential precipitation

The climatic conditions under which erosion is most rapid are

• Hot and moist

• Cold and dry

• Hot and dry

• Cold and moist

ASSERTION (A) : Pressure in the troposphere falls with increasing heights.

REASON (R) : The upper atmosphere has relatively low temperature.

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true , but (R) is false.

• (A) is false , but (R) is true.

ASSERTION (A) : The equatorial area at which the trade winds converge is known as Inter Tropical Convergence Zone(ITCZ).

REASON (R) : The ITCZ usually lies at or near the meteorological equator (doldrums).
