Challenge QuestionBased on the image what do you think is the relationship between depth of water and the speed of a wave?

Summary: The water movement on the shoreline is different depending on the time of the day. How this water moves in and out is called a tide and is impacted by the rotation of the earth, and the alignment of the sun and moon. Highest High and Lowest Low is caused by total alignment (Spring Tide). A right angle causes neap tides (Not as extreme).

Review #2• Can sound waves move through water? If so how
are they used?• Match terms to wave type (4 types from your
Frayer Models) Impacted by the Moon Capsizes Boats Rocking Motion Earthquakes• Period v. Frequency – Time for One Wave/Amount
of Waves in One Second – What is the relationship between the two?

Mapping Tidal Patterns – Part 1
1. Determine the Tidal Range2. Highlight your highest high tide and
lowest low tide (may be more than one) – Then mark these Spring Tides on the side of the chart.
3. Highlight your lowest high tide and highest low tide (may be more than one) – Now mark these Neap Tides on the side of the chart.

Mapping Tidal Patterns – Part 2LABEL THE X AND Y AXIS – X and YDetermine: What data goes on the X axis? How many lines will you have to complete this axis? Label your X axis and give it a Title.Determine: What data goes on the Y axis?
What do you notice about this axis? How many lines will you have to complete this axis? Label your Y axis and give it a Title.
Plot and Connect Each Point Together

Review #3
Which is spring and which is neap?How would you describe these tidal patterns to someone who asked?
