what best describes the same pattern of tides on earth throughout the day?
spring tides
neap tides
nocturnal tides
semidiurnal tides

In a place that has two roughly equal high tides and two roughly equal low tides each day, they're called "semidiurnal" tides.

The last 24 comments you added to a bunch of my answers on Sunday were all deleted before I saw any of them. I suspect there were more, but my notifications only went back as far as those 24.

I'm sad and upset that I didn't get to read any of them. To have somebody delete every single one of them, it must have been something really prime and juicy, and I'd like to have another chance to appreciate your work. Could you write it again, under THIS answer for me, and we'll see if it stays here long enough for me to see it ? Thank you.
