Re: double tide cause



Ah, I love a topic as regular as . . . .

oh never mind. It was going to be a weak joke anyway.

Every time this comes up, the usual suspects present their positions with
little change from the time before. I admit to being unsure about what is
right. I figure, though, that any explanation of tides needs to be able to
answer the following two questions.

1. Why does much of the Gulf of Mexico experience only one high and low tide
per day, rather than the usual two?

2. Why does Lake Ponchatrain (a relatively large, but shallow bay with a
very small connection to the Gulf) not experience tides of its own?
