Which is not true of the intertropical convergence zone? a. it's a high-pressure zone with sinking air. b. it features heavy precipitation. c. it is also known as the doldrums. d. it's where the trade winds collide.

It's a high-pressure zone with sinking air is not true of the Intertropical Convergence Zone. This is because the Intertropical Convergence Zone is low pressure zone with sinking air therefore it is wrong statement.

Intertropical Convergence Zone is the region surrounding Earth close to the Equator where the northeast and southeast trade blows meet. It features heavy precipitation. It is also known as the doldrums. It’s where the trade winds collide. These are all correct statements about the Intertropical Convergence Zone. It is a low pressure zone.

The correct answer is option A, that is, it is a high pressure zone with sinking air.

Explanation:

The intertropical convergence zone denotes a girdle of low pressure that encircles the Earth usually close to the equator where the trade winds of the Southern and the Northern Hemispheres combine together. It is featured by the convective activity that produces dynamic thunderstorms over the huge regions.  

The intertropical convergence zone possesses mounting air with common thunderstorms and consequent precipitation and is termed by the seamen as the doldrums. Thus, it is not a high-pressure zone with sinking air.  

a warm, wet climate will produce the highest rate of weathering. the warmer a climate is, the more types of vegetation it will have and the greater the rate of biological weathering (figure below). this happens because plants and bacteria grow and multiply faster in warmer temperatures.
