SOLAR SYSTEM

Detailed explanation-1: -When a tidal current moves toward the land and away from the sea, it “floods.” When it moves toward the sea away from the land, it “ebbs.” These tidal currents that ebb and flood in opposite directions are called “rectilinear” or “reversing” currents.

Detailed explanation-2: -Tidal Currents During a flood tide, when the water level is rising between low and high tides, the tidal current flows toward shore. During an ebb tide, when the water level is falling between high and low tides, the tidal current moves away from shore (Fig. 6.18).

Detailed explanation-3: -Tidal currents flow in one direction during part of the tidal cycle and in the opposite direction during the remainder of the tidal cycle. When tidal currents are directed toward the land, water levels rise in harbors and rivers; these are called flood tides.

Detailed explanation-4: -High tide flooding occurs when sea level rise combines with local factors to push water levels above the normal high tide mark. Changes in prevailing winds, shifts in ocean currents, and strong tidal forces (which occur during full or new moon) can all cause high tide flooding, inundating streets even on sunny days.
