NOAA- Tides
1. What is tides? The regular alternating rise and fall of sea level.
2. What causes tides? Explain in detail. The gravitational pull of the moon and sun.
3. Where do tides occur? Large lakes, atmosphere, even within solid earth.
4. Explain- High and low tides: When sea level rises, it's high tide. When sea level lowers, it's low tide.
5. Which object exerts the most force on the tidal bulge? Why? The moon, because it's closer to than the sun in to the Earth.
6. What happens when the sun and the moon align? What happens when they are perpendicular to each other? When they align the tides are strongest known as spring tides, and when they are perpendicular they are known as moderate tides.
7. What are some of the other factors that affect tides? Shape of coastline, sea floor, topography, river discharge and wind/weather
8. What are the zones of the intertidal zone? Spray zone, upper intertidal zone, mid intertidal zone, low intertidal zone, and subtidal zone.
9.What are some of the challenges for the critters of the intertidal zone? They can dry out, avoid predators, and withstand sunlight.
10. How do the intertidal organisms cope with the harsh environment? They form a layer and stay in groups, they have shells that close tight and they cement themselves onto rocks
11. What are some of the adaptations that help organisms cope with wave action? They have thick skin and suction, strong skeletons, thick shells, they cement themselves.
