Answer to q. 1

The buildup of salts decreases soil water potential. Reducing soil water potential can lead to plant
wilting because the movement of water from the soil into the roots and up to the leaves depends on a
water potential gradient. When soil water potential is at the wilting point, leaves will wilt.

Answer to q. 2

The lower the relative humidity, the lower (more negative) the water potential in the atmosphere. A
hot day will speed evaporation at the leaf surface. Air moving across a leaf surface carries water vapor
away.
