Hi! I was taking a practice test and came upon this question:

If the high tide of a diurnal tide occurs at 10:00 AM on one day, when will the next high tide occur?
a. 10:25 P.M. the same day
b. 10:50 A.M. the next day
c. 10:00 A.M. the next day
d. 10:00 P.M. the same day
e. 10:25 A.M. the next day

Now, I know that 1 high and 1 low tide occur per day with a diurnal tide. So, it has a period of ~24 hours. This eliminates choices A and D. How do I choose between B, C, and E?
`B.`

Tides have a period of 24 hours and 50 mins

Oh, thanks! So then, if the question asked about a semi-diurnal tide, would the answer be 10:25 PM the same day?

Can someone make a list of the formulas we need to know? It's my first time doing this event and States is in a few days. Thanks!

Does anyone know if Essentials of Oceanography (11th or 12th Edition) is helpful for this event?

Anyone know how to make a post, and not a reply? I'm new to the forums

Anybody know if the events for Dynamic Planet next year (2017) will follow the same pattern as it has before? The topics were like this: Glaciers (2013 & 2014), Oceanography (2015 & 2016). If so, would that mean that Glaciers is the next upcoming topic? Or unless they decide to add some new random topic...

1) Since you're new to the forums, I'll go ahead and give you the general note about not posting multiple times in a row within a short amount of time (use the "edit post" button at the top right of your post).
2) Dynamic Planet actually has (as far as I'm aware) four different topics: Oceanography (2016-2015), Glaciers (2014-2013), Freshwater, possibly under a different name (2012-2011), and Earthquakes and Volcanoes (2010-2009) which according to the SOSI schedule, is planned to rotate back next year (see this thread).
