    What is another name for the topography of the ocean floor?

    • Echo sounding

    • Oceanography

    • Hydroponics

    • Bathymetry

    Correct Answer
    A. Bathymetry
    Explanation
    Bathymetry is the measurement and mapping of the ocean floor's topography, including its depths, contours, and underwater features. It involves using various techniques such as echo sounding to determine the shape and characteristics of the ocean floor. Therefore, bathymetry is another name for the topography of the ocean floor.

    What forms the basis of a food chain in a deep ocean vent?

    • • Sediment

    • • Plants

    • • Tube Worms

    • • Bacteria

    Correct Answer
    A. • Bacteria
    Explanation
    Bacteria form the basis of a food chain in a deep ocean vent. Deep ocean vents are characterized by high temperatures and extreme pressure, making it difficult for other organisms to survive. Bacteria, however, have adapted to these harsh conditions and are able to derive energy from the chemicals present in the vent, such as hydrogen sulfide. These bacteria serve as primary producers, converting the chemical energy into organic matter. Other organisms, such as tube worms and other vent-dwelling animals, then feed on these bacteria, forming the basis of the food chain in this unique ecosystem.

    Because it is in the taxonomic Order Cetaceae, the Bottlenose Dolphin is most closely related to:

    • • Sharks

    • • Sailfish

    • • Whales

    • • Humans

    Correct Answer
    A. • Whales
    Explanation
    The Bottlenose Dolphin is most closely related to whales because they both belong to the taxonomic Order Cetaceae. This order includes all marine mammals such as dolphins, porpoises, and whales. Sharks and sailfish are not part of this order, and humans are not closely related to dolphins or whales in terms of taxonomy. Therefore, the correct answer is whales.

    An example of a transform active margin is:

    • • Mid-Atlantic Ridge

    • • San Andreas Fault

    • • West Coast of S. America

    • • East Coast U.S.

    Correct Answer
    A. • San Andreas Fault
    Explanation
    The San Andreas Fault is an example of a transform active margin because it is a boundary between two tectonic plates that are sliding past each other horizontally. This type of plate boundary is characterized by frequent earthquakes and the absence of significant volcanic activity. The fault is located in California, USA, and is responsible for the formation of the famous San Francisco Bay Area.

    What causes a wave to break?

    • • The wind blows it over open water

    • • It becomes unstable and collapses as shallow water slows

    • • Breakwaters built horizontal to the shoreline

    • • The surface water reaches an ocean trench

    Correct Answer
    A. • It becomes unstable and collapses as shallow water slows
    Explanation
    When a wave approaches shallow water, the bottom of the wave starts to interact with the ocean floor. This interaction causes the wave to slow down, while the top of the wave continues moving at its original speed. This difference in speed between the top and bottom of the wave causes the wave to become unstable and eventually collapse, resulting in the wave breaking.

    Which is NOT an example of a volcanic peak?

    • • Sea Knolls

    • • Guyots (Sea Mounts)

    • • Submarine Fans

    • • Abyssal Hills

    Correct Answer
    A. • Submarine Fans
    Explanation
    Submarine fans are not examples of volcanic peaks because they are sedimentary features found on the ocean floor, formed by the deposition of sediment carried by underwater currents. Volcanic peaks, on the other hand, are mountains or hills that are formed by volcanic activity, such as the eruption of lava and ash from a volcano. Sea Knolls, Guyots (Sea Mounts), and Abyssal Hills are all examples of underwater volcanic peaks or volcanic features.

    Which adaptation helps a marine animal that swims in open ocean water?

    • Markings such as Stripes and Mottling

    • Barbels

    • Uniform color and Reflective Scales

    • Bioluminescence

    Correct Answer
    A. Uniform color and Reflective Scales
    Explanation
    Uniform color and reflective scales are adaptations that help a marine animal that swims in open ocean water. Having a uniform color helps the animal blend in with its surroundings and makes it harder for predators to spot. Reflective scales can help to confuse or deter predators by reflecting light and creating a shimmering effect, making it difficult for predators to accurately locate the animal. These adaptations are beneficial for survival in the open ocean environment.

    When the Nike shoes traveling around the North Pacific Gyre landed along the coast of California, Hawaii, and Japan, the only current they would NOT have been carried by is the:

    • • Benguela Current

    • • North Pacific Current

    • • California Current

    • • Kuroshio Current

    Correct Answer
    A. • Benguela Current
    Explanation
    The Benguela Current is located along the western coast of southern Africa, and it flows northward. Therefore, it would not have been able to carry the Nike shoes from the North Pacific Gyre to the coasts of California, Hawaii, and Japan. The other three currents listed - the North Pacific Current, California Current, and Kuroshio Current - are all located in the North Pacific region and could have potentially carried the shoes to these locations.

    Another name for the tail fin of a fish is the:

    • • Caudal Fin

    • • Dorsal Fin

    • • Pelvic Fin

    • • Pectoral Fin

    Correct Answer
    A. • Caudal Fin
    Explanation
    The correct answer is Caudal Fin. The caudal fin is located at the posterior end of a fish and is responsible for propulsion and steering. It is the main fin used for swimming and is typically shaped like a fan or triangle. The dorsal fin is located on the back of the fish and provides stability, the pelvic fin is located on the ventral side of the fish and helps with balance and maneuvering, and the pectoral fin is located on the sides of the fish and aids in steering and stopping.
