Answer 2

Step-by-step explanation:

Groundwater is recharged naturally by rain and snow melt and to a smaller extent by surface water (rivers and lakes). ... Recharge can help move excess salts that accumulate in the root zone to deeper soil layers, or into the groundwater system. Tree roots increase water saturation into groundwater reducing water runoff.
