a region in the southern united states has seen a steady increase of the depth of its water table over the past 20 years. what does this data suggest?

a) the inhabitants of the area have learned to conserve groundwater.

b) precipitation in this area has increased over the past 20 years.

c) the groundwater is being filtered through impermeable rock faster.

d) the groundwater is being discharged faster than it is being recharged.

The groundwater is being discharged faster than it is being recharged is the data suggested.

Option D

Ground water level is the level of underground storage of water above the impermeable rock layer. The underground water is getting filtered through different layers of permeable rocks before it enters the final layer. So it’s fresh and ready to be consumed as it is taken out. Thus for centuries, it’s being used as the source of drinking water.

But with increasing population, the ground water is being consumed at the rate very faster than it can be refilled from different sources like precipitation, rivers and other water bodies. So its level tends to get lower and lower as this continues until the point it gets finished.  

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
