đ 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)
đ 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 âgoing outâ and âcoming inâ in the choices: which one matches the word âebbâ in normal tidal terminology?

Before You Answer
⢠Be clear on the difference between flood (one direction) and ebb (the opposite direction) currents.
⢠Match âebbâ 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).
