We went back to the same point in the Bay of Fundy this morning to see what it was like with the tide out.
As a reminder, here’s a picture with the tide in.
Here’s what the same location looked like this morning with the tide out.
Here’s another scene down the beach a ways. All the miles of sand you see will be covered with 10s of feet of water in a few hours.
There are lots of rocks like the one in the picture below along the beach. The rock is very soft here, and the deepest areas of carving indicate where the waves spend more time than elsewhere. Remember that the tide comes in and out like a sine wave, rapidly in the middle, but slowly at the top and bottom. So as the tide peaks out, it spends more time in the few feet near the top, and those rocks get more wear.
That’s amazing! It’s like a little city moves in between high tides.

Only a physicist would describe the tide as sine wave. I wonder if they use the tides to make power.

There is a tidal power plant in the bay. We visited it, and I’ll post on it when I get a chance
