tides
the tides when we were in the galapagos islands on the equator were nothing. like, tides? what tides? here in maine we watch a huge harbor regularly fill and empty. fill and empty. tides are caused by the moon. why are tides bigger here in maine than at the equator? this trend can't continue all the way to the north pole. otherwise there'd be a huge wall of water slowly spinning at the north pole. i guess i'll have to spend some spare brain cells on this one sometime.
