What are the Features, Hazards, and Risks to Humans associated with this plate boundary?
respond to other students — who posted about different plate boundary types than you — with the following information
Which plate boundary type would you prefer to live near?
The plate boundary I will be describing is ocean- ocean convergent boundary. The features of a ocean-ocean convergent boundary is that both plates collide and the most dense will subduct into it. The plate will rise through a rise of a volcano in the ocean.
A hazard of an ocean-ocean convergent boundary is the earthquakes, tsunami, and volcanic eruptions will occur. When there is a high magnitude earthquake, people will be alerted about a tsunami. In the case of a tsunami, people will have to reach a place of higher ground. Also for volcanoes, people are mandated to leave the island.
The geographic location that is featured in the video’s is Thailand, New Zealand (Australian plate), Japanese Coast Guard, and Northern Japan. Also, there were descriptions of the US explorers investigating underwater in the ocean. The features support the theory of plate tectonics for ocean-ocean convergent boundary is the older plate will subduct into the other plate, which initiates an earthquake. Afterwards, the plate will melt off the mantle materials to create a volcanic eruption, thus the subduction zone.
For this discussion, I chose Transform Faults.Although transform boundaries are boundaries where crust is typically neither created or destroyed, sometimes,
features of of transform faults are cracks in Earth’s surface, which can be seen in the form of trenches and
stream beds splitting in half. This happens because as the plates rub against one another, this can cause huge
stresses on the rocks between the two plates and cause the rock to break.
A hazard of transform faults are earthquakes. Because there are typically not many volcanoes around transform
faults, volcanic eruptions are not a common worry.
The transform fault in the video (San Andreas) showed the massive damage that such earthquakes can cause.
This can range from fallen trees and cracks in the sidewalk, from whole freeway bridges collapsing and trenches
opening up in the middle of the street that swallow up entire cars.
Geographic locations featured this video are cities in California (Los Angeles, San Francisco, deserted grassy area
that show cracks made by earthquakes). There was also a statement that indicated that the fault stretched from
Mexico to Oregon.
The Theory of Plate Tectonics states that Earth’s solid outer crust (lithosphere) is separated into plates that
move over the asthenosphere. When two plates meet, they can either converge, diverge, or sub against one
another — creating, destroying, or retaining parts of Earth’s exterior crust. In the case of transform boundaries,
pieces of Earth’s crust rub against one another, and this can cause so much friction that pieces break off —
resulting in cracks and trenches along these boundaries. These features demonstrate that Earth’s crust is in fact
separated into plates that move around, which cause damage.
