What are tides?
Does Lake Erie have tides? Um, no. Lake Erie can experience a seiche that is caused by winds, but not tides… Too small.
What causes tides? They are caused by the gravitational pull of the moon and the sun. The moon’s pull is stronger because it is closer.
Based on the Diagram, which are larger? SPRING TIDES Because the sun and moon are pulling in the same direction.
