To solve this problem, we need to understand the relationship between moon phases and tides as shown in your graph.
Step 1: Identify the Moon Phases
Look at the row of circles at the top. They show the moon changing shape over time.
* The
New Moon is when the moon is completely dark (the 4th circle).
* The
Full Moon is when the moon is completely lit up (the 5th circle).
Step 2: Look at the Graph Lines
* The
Red Line represents the highest high tides. You can see it goes very high (up to 5.5) and very low (down to 4.6). This big difference is called a
Spring Tide.
* The
Blue Line stays closer to the middle (around 5.0 to 5.2). This smaller difference is called a
Neap Tide.
Step 3: Connect the Phases to the Tides
* Find the
New Moon (dark circle) and the
Full Moon (bright circle) on the top row.
* Look directly down from those moons to the graph. You will see that the
Red Line has its highest peaks at these times.
* This means Spring Tides (highest highs and lowest lows) happen during the New Moon and Full Moon.
Conclusion:
The graph shows that the highest high tides occur when the moon is either completely dark or completely bright.
Final Answer:
Spring tides (the highest high tides) occur during the New Moon and Full Moon phases.
