100:00:00,008 --> 00:00:02,103K ocean what sort of assault200:00:03,003 --> 00:00:09,094the hi everyone join here for news at UT300:00:09,094 --> 00:00:13,253space LA recently we got a question frommaine a 7 1984400:00:14,099 --> 00:00:18,100asking why the oceans were salty andeveryone in the office kinda looked at500:00:18,109 --> 00:00:19,490each other when600:00:19,049 --> 00:00:22,848yeah why I'm going to assume she's notasking when the oceans are all sassy and700:00:23,289 --> 00:00:23,293better800:00:23,689 --> 00:00:26,782but instead is asking why their salt inthe oceans but not in our lakes and900:00:27,619 --> 00:00:28,260streams1000:00:28,026 --> 00:00:31,055except some lakes like the Great SaltLake I know1100:00:31,289 --> 00:00:35,550people in Utah and internet trollscheese for stop the salt in the oceans1200:00:35,055 --> 00:00:38,061is ninety percent the same chemicalmakeup as your table salt1300:00:38,061 --> 00:00:41,160good old NaCl sodium chloride is theonly kind of salter is there many1400:00:42,006 --> 00:00:43,010varieties because1500:00:43,064 --> 00:00:46,145assault is just a compound held togetherby an ironic bond what happens is an1600:00:47,045 --> 00:00:48,134Adam steals electron from another1700:00:49,034 --> 00:00:53,098and becomes negatively charged or and aneye on that attracted the positive cat1800:00:53,098 --> 00:00:54,157
eye on and two atoms bond
19
00:00:55,057 --> 00:00:58,476
so a lot different chemicals can come
together and make salts and because it
20
00:00:58,989 --> 00:01:00,920
is the ocean salt is also made a little
21
00:01:00,092 --> 00:01:03,481
magnesium calcium potassium and a
polyatomic
22
00:01:04,309 --> 00:01:07,850
an eye on made its offer and four
oxygens called sulfate
23
00:01:07,085 --> 00:01:10,111
but how does the salt get there from the
rocks on land
24
00:01:11,011 --> 00:01:15,072
actually according the US Geological
Survey dissolved co2 in rainwater makes
25
00:01:15,072 --> 00:01:18,129
slightly acidic eroding rocks when it
falls that's not the only tread water
26
00:01:19,029 --> 00:01:19,998
has up its sleeve
27
00:01:20,259 --> 00:01:24,810
and h2o molecule is polar the oxygen
atom hogs the electron so it's more
28
00:01:24,081 --> 00:01:26,179
negatively charged on one side and more
positively charged
29
00:01:27,079 --> 00:01:30,143
by hydrogen atoms when salter on water
they break apart because the only thing
30
00:01:31,043 --> 00:01:33,128
holding them in the crystal shape was
that my own attraction
31
00:01:34,028 --> 00:01:37,090
once the rain lands it flows downhill
carrying the dissolved minerals and ions
32
00:01:37,009 --> 00:01:38,101
to streams and lakes and rivers
33
00:01:39,082 --> 00:01:43,125
eventually the ocean the USGS also
points out salt comes from inside the
34
00:01:44,025 --> 00:01:44,092
ocean to
35
00:01:44,092 --> 00:01:47,931
volcanoes and hydrothermal vents heat
water so cans of some other basalt on
36
00:01:48,759 --> 00:01:48,768
the ocean floor
37
00:01:49,659 --> 00:01:52,790
adding salt to the mix but what is the
ocean stay salty
38
00:01:52,079 --> 00:01:55,157
because salt has been accumulating there
faster than it leaps some organisms use
39
00:01:56,057 --> 00:01:56,636
assault
40
00:01:57,149 --> 00:02:00,225
or the salt on the ocean floor take some
back but the exchange rate isn't even
41
00:02:00,909 --> 00:02:04,310
there's also a factor either that
poration water evaporates the molecule
42
00:02:04,031 --> 00:02:07,053
spread farther apart and the Magnetic
Pole for the vapor is enough to bring
43
00:02:07,053 --> 00:02:08,053
the ions with them
44
00:02:08,053 --> 00:02:11,081
as a result the salt stays behind and it
brings fresh water
45
00:02:11,081 --> 00:02:14,083
so long as the water doesn't get stuck
inland allow the Great Salt Lake
46
00:02:14,083 --> 00:02:18,151
slaney levels will stay below point zero
five percent compared to the 3.5 percent
47
00:02:19,051 --> 00:02:19,133
average salinity
48
00:02:20,033 --> 00:02:23,862
the oceans so there's lots of water up
here on the service but it turns out
49
00:02:24,159 --> 00:02:25,195
there might be plenty more
50
00:02:25,519 --> 00:02:29,572
hundreds of miles below doctor Karen
bond our guest host this episode the
51
00:02:30,049 --> 00:02:30,910
news explain
52
00:02:30,091 --> 00:02:34,116
it's often speculated that water is
trapped in the transition zone
53
00:02:35,016 --> 00:02:38,955
or the area between the upper and the
lower mantle layers of our planet and
54
00:02:39,099 --> 00:02:41,163
scientists have actually been looking
for it for decades
55
00:02:41,739 --> 00:02:44,750
this video was made because I love your
question we read them we store then we
56
00:02:44,849 --> 00:02:46,110
pick the ones we want to tackle
57
00:02:46,011 --> 00:02:49,042
that interest us or that we think you'll
like keep sending them our way in the
58
00:02:49,042 --> 00:02:51,090
comments or on Facebook and Twitter at
@attnews
59
00:02:51,009 --> 00:02:52,016
and I'll see all next time
