Tide Graphing and Interpretation

The video tutorial explains how to graph high and low tides over two days using data from Half Moon Bay, California. It covers the basics of tides, how they are created, and provides step-by-step instructions for setting up a graph with time and tide height axes. The tutorial guides viewers through plotting tide data points and connecting them to form a wave pattern, emphasizing the importance of estimating and labeling correctly.

What is the primary focus of the worksheet discussed in the video?

• Predicting weather patterns

• Calculating tide heights

• Graphing high and low tides

• Understanding ocean currents

How many days of tide data are being graphed in the worksheet?

• Four days

• Two days

• One day

• Three days

What is the starting point for the time axis on the graph?

• 6 AM

• 6 PM

• 12 PM

• 12 AM

What is the range of tide heights used on the graph's vertical axis?

• -1 to 7 feet

• -2 to 6 feet

• 0 to 5 feet

• -3 to 5 feet

Why is it important to include units on the tide height axis?

• To make the graph look professional

• To ensure accurate data interpretation

• To match the time axis

• To fill space on the graph

At what time does the first low tide occur on the first day?

• 6:45 PM

• 3:00 PM

• 11:59 AM

• 5:32 AM

What is the tide height at 11:59 AM on the first day?

• 3.5 feet

• 4.59 feet

• 2.75 feet

• 5.91 feet

What pattern is expected when connecting the plotted tide points?

• A straight line

• A zigzag pattern

• A wave pattern

• A circular pattern

How should the lines be drawn when connecting the tide points?

• Sharp angles

• Rounded at the top

• Zigzag lines

• Straight lines

What is the purpose of rounding the lines at the top of the graph?

• To make the graph look artistic

• To create a smooth wave pattern

• To highlight high tide points

• To save space on the graph
