Tides-NOAA
1. What are tides?
- the rise and fall of rising sea level caused by gravitational pull
2. What causes tides? Explain in detail (show in diagram)
- Tides are caused by the gravitational pull from the moon and the sun. The pull from the moon and sun pull seawater into two enormous bulges. One bulge is on one side closest to the moon and the other bulge is on the opposite side of the first one.

3. Where do tides occur?
- Large lakes, in the atmosphere, and in even within the solid earth
4. Explain-High and low tides (difference)
- High tides are when seawater reach their highest point or floods to its highest point, on the other hand, the low tides ebbs to the lowest point in seawater
5. Which object exerts the most force on the tidal bulge? Why?
- The moon exerts the most force on the tidal bulge because the sun is 27 million times more massive than the moon, which means the moon exerts twice as more tidal force
6. What happens when the moon and the sun align? What happens when they are perpendicular to each other?
- When the moon and the sun align, their gravitational pull combines to produce the highest and lowest tides called spring tides. When they are perpendicular to each other they pull at the seas from different sides called neap tides.
7. What are some of the other factors that affect tides?
- timing, size, and speed affect the tides
8. What are the zones of the intertidal zone?
- spray zone, upper intertidal zone, mid intertidal zone, low intertidal zone, and sub tidal zone
9. What are some of the challenges for the critters of the intertidal zone? Explain
- They have to avoid drying out during the low tides and escape predation from landscapes.
10. How do the intertidal organisms COPE with the harsh environment?
- they clump together in seaweed because of its tough leathery skin and would not have water loss and shelled organisms close tightly to get moisture
11. What are some of the adaptations that help organisms cope with wave action?
- some of the adaptations that help organisms cope with wave action are having thick skin and strong skeleton to handle wave action. Sea slugs have a strong foot to help them stick to surfaces. Clams and mussels have hard shells. The plants have firmly anchored roots and flexible stems. Fish have sturdy bodies and strong buddies.
