I. As population increases, people must pump more water into aquifers. II. As population increases, people must use more water to irrigate crops. III. As population increases, people must treat more gray and black water. I only II only III only I and II only II and III only

like a layer of water
eyust707
  • eyust707
yep a very special one underground because its filtered by all the dirt and is usually clean enough to drink or water crops with
eyust707
  • eyust707
We typically pump water up from the aquifer not in to it.
eyust707
  • eyust707
In fact sometimes its illegal to pump water from the surface back in to the aquifer

lol
eyust707
  • eyust707
So it cant be I
anonymous
  • anonymous
so that is out
eyust707
  • eyust707
yup what are you thinking for the next two?
anonymous
  • anonymous
i think it could be II only
eyust707
  • eyust707
Do you know what grey and black water is?
eyust707
  • eyust707
II is correct btw but what about III
anonymous
  • anonymous
oh that is also true thank you so much
eyust707
  • eyust707
yup no problem

Which of the following water bodies is most likely polluted? a stream with a pH of 6.3 a river with a large stonefly population a pond with low levels of fecal coliform a reservoir with a turbidity of 0.4 NTUs a lake with low levels of dissolved oxygen
eyust707
  • eyust707
Whats a really high ph? whats a really low ph? what a nuetral Ph?
eyust707
  • eyust707
Or better yet which ones can you eliminate for sure
anonymous
  • anonymous
high ph is a base. low is a acid
eyust707
  • eyust707
yep. 14 is really high 2 is realy low 7 is nuetral
eyust707
  • eyust707
6.3 is almost neutral and often times well find that surface water is slightly acidic anyways so 6.3 is a healthy ph for a stream
eyust707
  • eyust707
are there any other ones you feel you can rule out?
anonymous
  • anonymous
we should rule out the second choice
eyust707
  • eyust707
ok any others?
anonymous
  • anonymous
the third choice
eyust707
  • eyust707
I agree
eyust707
  • eyust707
Now we have left one about turbidity and one about dissolved oxygen
anonymous
  • anonymous
I think the answer is the last option
eyust707
  • eyust707
Correct
anonymous
  • anonymous
ok i have one more question
anonymous
  • anonymous
this a math/ science one
eyust707
  • eyust707
In the last 50 to 75 years we started using petroleum products mined from deep inside the earth to initiate a chemical reaction that takes nitrogen from the air and creates a chemical that looks a lot like salt. That chemical version of nitrogen is vital for plant grow and we realized that we could apply it to our crops and it would make our plants grow super big. Now farmers use it a lot and somtimes it ends up in our lakes. Well algea can grow off this nitrogen too. Like all plants the algea also needs oxygen inside the water. So when a lake gets polluted with nitrates a ton of algea gros, the algea uses all the oxygen in the water and then the fish and other aquatic life is left with very little oxygen to survive.

If you'ce curious its called the haber-bosch process and aquatic dead zones.

  • anonymous
thank you so much

There are approximately 1,386 million cubic kilometers (km3) of water on Earth. Approximately how much of that total is saline? 4,158,000 km3 41,580,000 km3 134,442,000 km3 415,800,000 km3 1,344,420,000 km3

Remember how I said that the aquifer was very special?
eyust707
  • eyust707
This question explains why
anonymous
  • anonymous
true
eyust707
  • eyust707
97.5% of our water has salt in it
eyust707
  • eyust707
"saline" btw means salty
anonymous
  • anonymous
I think I can solve this one
eyust707
  • eyust707
no need to solve only one answer is even remotely close
anonymous
  • anonymous
ik
anonymous
  • anonymous
the last option lol
eyust707
  • eyust707
yup
anonymous
  • anonymous
Well alright thanks for the great help
