🔍 Key Concepts

• Tidal currents associated with the rising and falling of the tide • Difference between flood current and ebb current • Direction of water movement: toward vs away from a reference point (such as shore or upstream/downstream)

💭 Think About

• When the tide is rising and water moves toward the land or upstream, what is that generally called? • When the tide is falling and water moves away from the land or toward the sea, what term is used for that current? • Look at the words ‘going out’ and ‘coming in’ in the choices: which one matches the word ‘ebb’ in normal tidal terminology?

✅ Before You Answer

• Be clear on the difference between flood (one direction) and ebb (the opposite direction) currents. • Match ‘ebb’ with whether the water level is generally increasing or decreasing. • Verify which choice describes water moving away from the primary reference point (harbor/shore/upstream).
