No, tides are caused by the gravitational pull of the Sun and Moon, not by currents.

Tidal currents are not quite the same thing as tides. Tidal currents are horizontal movements of water caused by the tides.
The beach was formed be the tide.
It is much too cold to wash them out tide.
Two slack tidal currents usually occur each day, one at high tide and the other at low tide.
Gravity for two reasons * The water moves from a higher region to a lower one (mostly for rivers) * The moons gravity causes high a low tide, this pull the water up then drop it causing the water to stir around in currents (this is mostly for oceans)
'Neap' Tides. At high tide a neap tide is not as high as a Spring High tide. At Low tide a neap tide is not as low as a spring Low Tide. At a given point on Earth, a Sprimg tide may have a range of 30 feet. At the same point on Earth, a Neap tide may only have a range of say 20 feet.
It means that the tide currents have shifted. There are two main tides: high tide and low tide. When the tide is high or rising toward high, currents are driven toward the beach. When it is low or dropping toward low, the currents are driven away from the beach. Some people also use the term to refer to life situations that change. You could say "the tide turned" when someone was seriously ill and became better, or if things were looking bad for someone and changed to a good outlook.
