Find answers to hard questions at the SciJinks Weather Laboratory. Now, students can find answers to tidal mysteries on our web site. What causes the tides? We might remember that it has something to do with the Moon. But then why do we have two high tides each day if the Moon only rises and sets once? And why don’t the tides occur at the same time every day? All is revealed in a new “How & Why” page on the middle‑school‑level NOAA/NASA SciJinks Weather Laboratory website, http://scijinks.gov. Click on the “How & Why” button.
