Imagine That You Work For The Davey Jones Locker Travel Group And You

Imagine that you work for the Davey Jones' Locker travel group and you want to offer an educational submarine tour showcasing ocean features and landforms. Create a PowerPoint slideshow advertising a deep-sea tour of the world ocean. Your submission must address the following: Your PowerPoint presentation should: Have a title slide. Contain at least 3 content slides. Reflect proper spelling and grammar.

Cite at least 2 credible references and present the sources in APA format on a References slide. Select at least 3 features/landforms found on the ocean floor to include in your tour. You can choose from these ocean feature/landform examples or decide to find your own instead. For each feature that will be visited on the tour, address the following: Name the feature and describe what type of ocean landform it is. Provide an image from a bathymetric map showing the feature up-close (like those provided in the examples above). Describe how plate tectonics relates to the feature: Include a summary of the geologic process(es) involved in the feature's formation. Indicate whether the feature is found at an active margin, passive margin, or in the abyss.

Paper For Above instruction

The proposed educational submarine tour by the Davey Jones' Locker Travel Group aims to immerse participants in the fascinating and diverse features of the ocean floor. Highlighting key landforms such as mid-ocean ridges, deep-sea trenches, and seamounts, this tour offers an unparalleled glimpse into the dynamic geologic processes shaping our planet’s underwater landscape.

Mid-Ocean Ridges

Mid-ocean ridges are continuous mountain ranges submerged beneath the ocean, stretching across the globe and formed by divergent plate boundaries where tectonic plates are moving apart. These underwater mountain chains are indicative of seafloor spreading, a process whereby magma rises from the mantle to create new oceanic crust. As plates diverge, magma solidifies at the boundary, constructing the ridge over time. An example of a prominent mid-ocean ridge is the Mid-Atlantic Ridge, which runs down the center of the Atlantic Ocean.

These ridges are typically located at an active divergent margin. The geologic activity involved includes seafloor spreading, volcanic activity, and earthquakes associated with tectonic movements. This process recycles oceanic crust and forms new seafloor, contributing significantly to plate tectonics and the dynamic nature of ocean basins (Gordon & Cox, 2009).

Deep-Sea Trenches

Deep-sea trenches are the deepest parts of the ocean, where one tectonic plate subducts beneath another. These landforms are elongated, narrow depressions formed at convergent plate boundaries, especially at active margins. An example is the Mariana Trench in the western Pacific Ocean, which reaches depths of over 36,000 feet.

Trenches form through subduction processes, where dense oceanic crust is pulled beneath lighter continental or oceanic plates, leading to intense geological activity, including earthquakes and volcanic eruptions. Subduction zones are typically found at active margins where plates actively converge, and the intense geological processes involved are crucial in recycling the Earth's crust (Lallemand et al., 2008). This process also causes trench formation and deep-sea sediment accumulation.

Seamounts

Seamounts are isolated underwater mountains formed by volcanic activity, usually originating from the ocean floor and often rising thousands of meters above the seafloor. These features are typically found in the abyssal plains and are formed as volcanoes that never reach the ocean surface. An example is the Cobb Seamount in the North Pacific Ocean.

Seamounts are generally associated with volcanic hot spots or divergent plate boundaries. Their formation involves magma rising from the mantle through volcanic activity, which creates submarine volcanoes. This process is related to mantle plumes or hot spots and occurs away from active margins, primarily within the abyssal plain regions. Seamounts can influence ocean currents and are important habitats for marine life (Wessel & Smith, 1998).

Conclusion

This submarine tour provides a vivid exploration of the ocean's landforms, emphasizing the intricate relationship between geological processes and oceanic features. Understanding these features offers insights into plate tectonics' vital role in shaping Earth's surface, highlighting the dynamic and ever-changing nature of our planet. By visiting mid-ocean ridges, trenches, and seamounts, travelers gain a deeper appreciation of Earth's geological activity and the processes that sustain life beneath the waves.
