Why there is tide on sea but not in ponds?

There is a tidal effect on ponds. We don't see it because the pond is much smaller than the sea, and thus so is the tide. Any body of water will experience a force from the Moon based on Newton's law of gravity. read more

But then, the tide is about how much water that moves to and from in a period of 12 hours and 25 minutes. Look at a cotidal chart and you will understand why there are epicenters where the water doesn’t move at all. read more

Firstly, tides are not simply caused by the gravitational pull of the moon as such. The moon doesn't revolve around the Earth precisely. They both revolve around their mutual centre of gravity, but because the Earth is so much heavier this means that the moon travels in large circles while the Earth travels in very small circles. read more
