2. When the salinity of ocean water increases through freezing the water becomes more dense and sinks 3. When the salinity of the ocean water increases through evaporation, the salt is left behind and the water becomes more dense and sinks 16. Most waves form when__________ Winds blowing across the water’s surface transmit their energy to the water. 17. The size of a wave depends on what three 1. Strength of the wind- stronger winds create larger waves things. 2. The length of time the wind blows- the longer the winds blows the larger the wave 3. The distance over which the wind blows- winds blowing across longer distances build up bigger waves 18. The ______________ of the wave moves 1. energy toward the shore, but the ____________ 2. water remains where it was. 19. Draw and label the parts of a wave: crest, trough, wavelength, and Wave Height. 20. What happens to the wavelength and the The wave height increases and the wave length decreases wave height as the wave approaches the shore? 21. _____________ is the rise and fall of Tides Earth’s waters on its coastlines. 22. What force causes the tides to occur on Gravity Earth’s surface? 22. Why does the moon’s gravitational pull The Moon is closer to the Earth have a greater influence on Earth’s waters when compared to the Sun? The Sun is the most massive body in our Solar System. 23. How many high tides and low tides occur 2 high tides and 2 low tides each day (24 hour period)? 24. What is a tidal range? The difference between the water levels during high and low tides 26. Diagram and Label a Spring Tide: Sun, Earth, Moon, and tidal bulge. 27. In which phases of the moon do Springs New moon and Full Moon Tides occur? 28. Why is the tidal range the greatest during a The combined gravitational pull of the Sun and Moon Spring Tide?
