1: What are tides?
Tides are the alternating rise and fall of sea level due to the moon's gravitational pull.
2: What causes tides?
The thing that causes tides are forces that are generated by the gravitational pull of the moon and the sun and the rotaion of the earth, tug sea water into two enormous buldges.
3: Where do tides occur?
Tides occur where the buldge is located on the edge of the planet closest to the moon. The other forms at the opposite side of the planet.
4: Explain the difference between high and low tides.
High tides are when the sea level rises up to it's highest point and low tides are when the sea level drops, or ebbs, to it's lowest tide point.
5: Which object exerts the most force on the tidal bulge? Why?
Even though the sun is larger and has more mass, the moon is closer so it exerts the most force.
6: What happens when the sun and moon align?
When the sun and moon align, they combine gravitational forces producing the highest and lowest tides called Spring Tides.
7: What are some of the other factors that affect tides?
The range, magnitude, and the shape of the sea floor.
8: What are the zones of the inter-tidal zone?
Along most shores, the intertidal zone can be clearly separated into the following subzones: high tide zone, middle tide zone, and low tidezone. The intertidal zone is one of a number of marine biomes or habitats, including estuaries, neritic, surface and deep zones.
9: What are some of the challenges for the critters of the inter tidal zone? Explain.
The Intertidal Zone is a very harsh living environment for organisms because it is always changing conditions. Animals in this zone are constantly facing challenges such as varying salinity, drying out by wind and sunlight, predators, strong currents that carry them back to sea, and varying weather conditions.
10: How do the inter tidal organisms COPE with the harsh environment?
Some animals, such as sea urchins, carve holes in the rocks and hide in these holes that provide moisture during low tide. Mussels and other shell organisms will tightly close their shell to keep in moisture. Snails secrete a slime that gives them moisture during the long hours of low tide and anemones will fold in their tentacles to hold in moisture. Each of these techniques help the creatures from drying out.
11: What are some of the adaptations that help organisms cope with wave action?
The animals can use rocks, shells, and suction cups to stay in place when strong waves hit.
