1. *Refer to Chapter 12 in your Textbook

2. Learning Goals: 1. I can explain how tidal waves are generated. 2. I can differentiate between the various types of tides. 3. I can describe an intertidal habitat.

3. Tidal Generated Waves: The gravitational pull from the Sun and Moon causes high and low tides Moon has a greater influence because it is closer to Earth

4. Tides differ around the world: One high tide and one low tide each day = Diurnal Two two high tides and two low tides each day = Semi-diurnal

5. Spring and Neap Tides: Spring Tides: occur when the Sun, Moon, and Earth are in a straight line Occurs at new and full moons Have the greatest effect on tides Neap Tides: occur when the Sun, Moon, and Earth make a right angle Occurs at first and third quarter moons

6. Spring and Neap Tides:

7. Extreme Tides: Bay of Fundy- Nova Scotia, Canada Largest tidal range in the world Approximately 48-55 ft (FL is about 4 ft)

9. Tidal Bores: Occur when incoming tides produce a wave that flows into a narrow area (river, bay) Only occur in a few places around the world

10. Intertidal Habitat: “Tide Pools” Covered with water during high tide, and exposed to air during low tide Must adapt to harsh conditions like waves & drying out
