big ideas
. ocean waves develop as a result of wind and like all waves are a form of energy transfer.
. characteristics of waves, such as wavelength, period, frequency and speed, can be measured and calculated.
. waves impact organisms living on and near the coast.

in this lesson, you will learn about waves, how they form and how they impact marine organisms. use the chart below to record what you already know about these topics. after you complete the lesson, use the chart to record new information you learned.
before reading and trying the activities in your textbook, think about the questions below. record what you know about each topic in the what i know column of the chart.

question	what i know	what i learned
how do ocean waves form?
how do waves affect landforms?
how do waves affect marine and coastal organisms?
how are waves important to people?

Explanation:

Ocean waves form mainly due to wind - wind blowing over the water surface transfers energy creating waves. Waves affect landforms through processes like erosion (undercutting cliffs) and deposition (building sandbars). They impact marine and coastal organisms by influencing habitats (wave action can create sheltered or exposed areas), food availability (affecting plankton distribution). Waves are important to people for activities like surfing, fishing, and also in terms of coastal protection (breaking waves can reduce storm - surge impacts).

Answer:

Question	What I Know	What I Learned
How do waves affect landforms?	Can erode and deposit materials.	Specific landform changes like formation of sea caves, spits.
How do waves affect marine and coastal organisms?	Influence habitats and food availability.	How different species adapt to wave - related conditions.
How are waves important to people?	For recreation and fishing.	Their role in coastal protection and energy generation potential.
