Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
<h3>What is humidity?</h3>
Humidity is used to determine the concentration of water vapour that is available in the air.
when the vapour is high there is high relative humidity when the vapour is low there is low relative humidity and water leaves the surface of leaf fast.
Therefore, Leaves in areas of low humidity have a steeper concentration gradient so water diffuses out of the leaf fast.
