<v Speaker 1>brain Stuff from how Stuff works dot com where smart happens. Hi,

0:00:27.360 --> 0:00:31.840
<v Speaker 1>I'm Marshall Brain with today's question, what causes high tides

0:00:31.880 --> 0:00:35.440
<v Speaker 1>and low tides? And why are there two tides every day?

0:00:36.080 --> 0:00:39.520
<v Speaker 1>Think about the Moon. It's close enough and big enough

0:00:39.560 --> 0:00:42.680
<v Speaker 1>that it affects the oceans on Earth. You can imagine

0:00:42.720 --> 0:00:46.200
<v Speaker 1>that wherever the Moon is in its rotation, the water

0:00:46.400 --> 0:00:50.120
<v Speaker 1>is deeper at that point on Earth. The Moon's gravitational

0:00:50.200 --> 0:00:53.160
<v Speaker 1>force pulls on water in the oceans, so that there's

0:00:53.200 --> 0:00:56.319
<v Speaker 1>a bulge of water underneath the Moon. But there are

0:00:56.320 --> 0:00:59.720
<v Speaker 1>actually bulges in the ocean on both sides of the planet.

0:01:00.160 --> 0:01:02.600
<v Speaker 1>The bulge on the side of the Earth opposite the

0:01:02.600 --> 0:01:05.880
<v Speaker 1>Moon is caused by the Moon pulling the Earth away

0:01:06.000 --> 0:01:09.200
<v Speaker 1>from the water on that side. If you're on the

0:01:09.240 --> 0:01:12.600
<v Speaker 1>coast and the moon is directly overhead, you should experience

0:01:12.680 --> 0:01:15.920
<v Speaker 1>high tide. If the moon is directly overhead. On the

0:01:16.000 --> 0:01:19.920
<v Speaker 1>opposite side of the planet, you also experience a high tide.

0:01:20.280 --> 0:01:23.920
<v Speaker 1>Between these high tides are the low tides. During the day,

0:01:24.080 --> 0:01:27.600
<v Speaker 1>the Earth rotates a hundred eighty degrees in twelve hours.

0:01:27.959 --> 0:01:31.399
<v Speaker 1>The moon, meanwhile, rotates six degrees around the Earth in

0:01:31.480 --> 0:01:36.240
<v Speaker 1>twelve hours. The twin bulges and the moon's rotation mean

0:01:36.319 --> 0:01:40.800
<v Speaker 1>that any given coastal city experiences a high tide every

0:01:40.880 --> 0:01:45.280
<v Speaker 1>twelve hours and twenty five minutes or so. For more
