1. what makes up the salt in the ocean? (like ions)
2. place the following in order of most salinity to least: oligohaline, saline, euhaline, brine, polyhaline
3. what is primary and secondary salinity?

salt!

1. Chloride (Cl-) and sodium (Na+) ions
2. oligohaline, polyhaline, euhaline, saline, brine
3. Primary is naturally occurring while secondary is as a result of human activities (had to look this one up. great question!)

1. correct!
2. correct, but your order is least to most salinity, and it should be flipped
3. correct!
your turn

1. they filter feed so like they just let currents take food to them.
2. it uses its toothy radula to saw through it and then eats the soft stuff.
3. butterfly fishes, sweetlips, snappers

Yeah, the only addition I would make for 1 is they have specialized cells to produce those currents.
Your turn!

oops just realized i was supposed to post the next question ahhhhh >w<
sediments seem yummy! lol not really
1. what is the standard measurement for turbidity? what is the global standard for drinking water? what is ideal?
2. what are some ways to decrease sediment pollution?
3. how much erosion is natural and how much is human related? (in terms of US sediment production)

1)NTUs, <1 NTU, 0 NTU
2)Silt fences, grow plants near the edge of the water, essentially anything to limit runoff.
3)I honestly have no clue without looking it up..... Looked up answer: Natural: 0.8–1.9 Mg/ha/year Human-Derived: 6 Mg/ha/year

3 was a really good question.... wow!
1. the WHO says <5NTUs for drinking water, <1 ideally
2. yeap
3. i actually was looking for a percentage that 30% is natural and 70% is anthropogenic, but if you take 1.9 as the amount of natural sediment, it does come out to be a little under 30%!
