Explain the difference between the theories of Plate tectonics and Continental drift. * Continental drift: The movement, formation, or re-formation of continents described by the theory of plate tectonics.
* Plate tectonics: A theory that explains the global distribution of geological phenomena such as seismicity, volcanism, continental drift, and mountain building in terms of the formation, destruction, movement, and interaction of the earth's lithospheric plates.
Describe the 3 types of color patterns commonly found in fish. * Counter shading - The dorsal or top of the fish is darker than the bottom of the fish, making them difficult to see as they blend into the darkness of the deeper water when viewed from above or blend into the brightness of sunlit waters when viewed from below. Many predators use this form of coloration. * Cryptic - Bottom dwelling and reef fish often use chromatophores to blend in perfectly with their surroundings. Often, these fish are bottom dwellers that blend in with the stratum they rest on. * Disruptive - Many fish use their coloration to form strongly contrasting patterns that break up the outline of their body making it difficult for predators to see them at all.
Describe divergent, convergent and transform plate boundaries and tell what each results in. * Divergent Plate Movement (plates move away from each other)- Continental and continental, oceanic and oceanic. * Convergent Plate Movement (plates move towards each other)- Continental and Oceanic, Oceanic and Oceanic, Continental and Continental. * Transform Plate Movement (plates sliding past each other)- Continental and Continental
Explain the difference in planetary alignment and tidal ranges for spring and neap tides. * Neap tides represent the smallest tidal range. This occurs when the sun and moon are at right angles,
