Ocean Tides Worksheet - Flying Colors Science - Free Printable

Since you did not select any specific options (ExplainAnswer, TeachTopic, or GeneratePractice are all false), I will provide the solutions to the visible questions on the worksheet directly.

Here are the answers based on the graphs and diagrams shown in the "Tides Review" section:

1. The graph shows that high tides in Boston occur every...
* Reasoning: Look at the time between two high peaks. The first high tide is around 3 AM Monday. The next high tide is around 3 PM Monday. That is a 12-hour difference. The next one is around 3 AM Tuesday.
* Answer: c. 12 hours

2. At approximately what time was the first high tide on Monday?
* Reasoning: Look at the "Monday" section of the graph. The first peak (highest point) aligns with the mark halfway between Midnight and 6 AM.
* Answer: a. 3 AM

3. At approximately what time was the first low tide on Tuesday?
* Reasoning: Look at the "Tuesday" section. The first valley (lowest point) occurs right after midnight. It aligns with the 3 AM mark (halfway between Midnight and 6 AM).
* Answer: a. 3 AM *(Note: Option 'a' says 2 AM in some versions, but visually it is closest to 3 AM. If 3 AM isn't an option, choose the closest early morning time like 2 AM or 4 AM depending on the specific choices provided. Based on standard tidal patterns shown here, it is approx 3 AM).* Looking closely at the options provided in the image for #3: a. 2 AM, b. 9 AM, c. 3 PM, d. 9 PM. The low tide is clearly in the early morning. a. 2 AM is the best fit among the choices.

4. At approximately what time will the next low tide occur (on Wednesday)?
* Reasoning: Tides repeat roughly every 12 hours. The last low tide shown is Tuesday around 9 PM (21:00). Add 12 hours to 9 PM Tuesday -> 9 AM Wednesday.
* Answer: b. 9 AM

5. At approximately what time will the next high tide occur (on Wednesday)?
* Reasoning: The last high tide shown is Tuesday around 3 PM (15:00). Add 12 hours to 3 PM Tuesday -> 3 AM Wednesday.
* Answer: a. 3 AM

6. If the trend shown by the graph continues, what will be the water level of the next low tide?
* Reasoning: Look at the height of the previous low tides. They are all hovering around the 0.5 meters line on the y-axis.
* Answer: a. 0.5 meters

7. Which inference about tides is best made from the given graph?
* Reasoning: The graph shows a repeating wave pattern. It goes up and down regularly. This means it is a cycle.
* Answer: c. The tidal change is a cycle.

8. The Moon has a greater effect on the Earth's ocean tides than the Sun has because the...
* Reasoning: Even though the Sun is bigger, the Moon is much closer to Earth. Gravity gets weaker the farther away you are. Because the Moon is close, its pull is stronger on our oceans.
* Answer: a. Moon is closer to the Earth than the Sun is

Answers for the Diagram Questions (Right Side):

Question regarding Spring Tides (Positions 1 and 5):
* Reasoning: Spring tides happen when the Sun, Moon, and Earth are in a straight line. This creates the strongest pull. In the diagram, Position 1 (New Moon) and Position 5 (Full Moon) are in a straight line with the Sun and Earth.
* Answer: Positions 1 and 5 cause spring tides.

Question regarding Neap Tides (Positions 3 and 7):
* Reasoning: Neap tides happen when the Sun and Moon are at right angles (90 degrees) to each other relative to Earth. This cancels out some of the pull. In the diagram, Position 3 and Position 7 form a right angle with the Sun/Earth line.
* Answer: Positions 3 and 7 cause neap tides.

Question about Figure One vs Figure Two:
* Reasoning:
* Figure One shows the Moon at positions A and C (aligned with Sun/Earth). This causes Spring Tides (higher highs, lower lows).
* Figure Two shows the Moon at positions B and D (right angles to Sun/Earth). This causes Neap Tides (lower highs, higher lows).
* Answer: Figure One represents Spring Tides. Figure Two represents Neap Tides.
