GROUNDWATER

 Expand the GROUNDWATER folder. Double‑click and fineeded Gray County, Kansas.

This is Gray County, Kansas. As you can discriminate from the nature pivot irrigation circles, cultivation is the dominant plant use in the county. The Arkansas Large stream – open west to east – bisects the county. There is not ample inaccessible in the large stream to furnish competent inaccessible for irrigation. Therefore, inaccessible fountain for irrigation is basiswater.

We cannot see the aquifer that is supplying the inaccessible for irrigation, but we do feel polite-behaved-behaved-behaved-behaved notification that indicates the profoundness of the inaccessible board. In open, we exhibit the deeper the inaccessible board, the deeper the polite-behaved-behaved-behaved.

 Double‑click and fineeded Well Depths.

This map shows the profoundness of the inaccessible board. It was composed using grounds from 100 polite-behaved-behaved-behaveds. The further yellow the area, the shalinferior the polite-behaved-behaved-behaved-behaved and the further blue-colored, the deeper. The deepest polite-behaved-behaved-behaveds feel a profoundness of closely 500 feet.

 Double‑click and fineed, Surface Profile. Right‑click Surface Profile, and then fineeded Show Loftiness Profile.

This surface profinish cord is closely 25 miles in elongation and the loftiness varies by 24 meters barely. This is not fur vary in loftiness balance 25 miles.

With the loftiness profinish showing at the deep of the protect, run your cursor along the x-axis. Look at the situation of the red arrow, not-absolute to the polite-behaved-behaved-behaved-behaved profoundness map.

Question 25: What is the conformity betwixt demeanor loftiness and polite-behaved-behaved-behaved-behaved profoundness?

A.   In open, the prouder the plant loftiness, the deeper the polite-behaved-behaved-behaved-behaved profoundness

B.   In open, the inferior the plant loftiness, the deeper the polite-behaved-behaved-behaved-behaved profoundness

C.   In open, the prouder the plant loftiness, the shalinferior the polite-behaved-behaved-behaved-behaved profoundness

D.   Unefficient to discriminate from vision

 

Question 26: What does this conformity hint?

A.   In this area, basisinaccessible flattens tends to soar and decline after a while the topography of the plant

B.   In this area, basisinaccessible flattens are not-absolutely the same

C.   In this area, polite-behaved-behaved-behaveds are barely drilled where the basisinaccessible flatten is nigh the demeanor

D.   Unefficient to determine.

 Double‑click and fineeded Withdrawal.

This is a map of the Proud Plains aquifer showing varys in the inaccessible tefficient flatten for a twenty year age (1980-1999). Green areas are not-absolutely lasting, but as the pretense varys from yellow to red to pink, the flatten of the inaccessible tefficient declines, balance 60 feet in the pink areas. The dominant plant use is cultivation.

Question 27: Why is the inaccessible flatten in some portions of the Proud Plains aquifer missing? (Check all that use).

A.   Agricultural use is after a whiledrawing inaccessible

B.   Recharge rates are less than after a whiledrawal rates

C.   Recharge rates are further than after a whiledrawal rates

D.   Unefficient to determine
