What tectonic setting is primarily responsible for producing Olympic National Park?
What tectonic setting is primarily responsible for producing Olympic National Park as well as the hills on which San Francisco is built? Hot-spot.
What tectonic setting has been primarily responsible for producing Mt St Helens?
St. Helens sits above a subduction zone, where one tectonic plate goes below another as they come together.
What was going on geologically that caused the earthquake that knocked down much of San Francisco in 1906?
What was going on geologically that caused the earthquake that knocked down much of San Francisco in 1906? Slide-past motion along a great fault. Feedback: Not much mountain-building is happening along the central coast of California; the rocks slide past horizontally.
What tectonic setting is responsible for the heat and lava at Yellowstone?
What tectonic setting is responsible for the heat and lava at Yellowstone? About 2.1 million years ago the movement of the North American plate brought the Yellowstone area closer to the shallow magma body. This volcanism remains a driving force in Yellowstone today.
What is formed at a subduction zone?
Oceanic trenches are formed at subduction zones. Oceanic plates meet continental plates in the water, so trenches are formed as the oceanic plate goes under the continental plate. These trenches can be very deep if the plate that is subducting (going down) is an older and colder plate.
Which type of tectonic boundary is associated with subduction zone?
Convergent boundaries Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust. The denser plate is subducted underneath the less dense plate.
What kind of volcano is Mount Saint Helens plate tectonics?
stratovolcano Mount St. Helens is a stratovolcano, a steep-sided volcano located in the Pacific Northwest region of the United States in the state of Washington.
What is Mt St Helens made of?
Mount St. Helens is an example of a composite or stratovolcano. These are explosive volcanoes that are generally steep-sided, symmetrical cones built up by the accumulation of debris from previous eruptions and consist of alternating layers of lava flows, volcanic ash and cinder.
What tectonic plates caused the San Francisco earthquake 1989?
The Fault. The San Andreas Fault is the boundary between the North American plate and the Pacific plate.
What type of tectonic plate boundary is the San Andreas Fault?
transform plate boundary Tectonic Plate Boundaries The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.
What type of plate boundary is Yellowstone volcano?
Yellowstone is situated with a tectonic plate not a plate boundary.
What causes the Yellowstone hotspot?
Yellowstone sits above a melting anomaly within the Earth, called a “hotspot.” This hotspot is powered by a plume of hot (but not molten) material that may extend as deep as the boundary between the planet's mantle and core.
What is formed on top of plate B?
what is formed on top of plate B? Answer: Magma rise up on top of plate B to form volcanoes. As the leading edge of plate A subducted beneath plate B, it move towards the mantle and melts when it reaches the mantle due to high temperature in the mantle.
Which plate boundary has a subduction zone?
convergent plate boundaries Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.
What does divergent plate boundaries cause?
A divergent boundary occurs when two tectonic plates move away from each other. Along these boundaries, earthquakes are common and magma (molten rock) rises from the Earth's mantle to the surface, solidifying to create new oceanic crust.
What does convergent boundary cause?
A convergent plate boundary is a location where two tectonic plates are moving toward each other, often causing one plate to slide below the other (in a process known as subduction). The collision of tectonic plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
What type of volcano is Crater Lake?
Stratovolcanoes Stratovolcanoes, also called composite volcanoes, tend to have a steep-sided conical form and highly explosive eruptions. Earlier eruptions built Mount Scott, which lies east of Crater Lake.
Which tectonic plate interaction caused the Alaska earthquake *?
plate convergence Earth scientists now recognize that the 1964 Great Alaska Earthquake resulted from plate convergence: where the Pacific Plate is being overridden by the North American Plate, it descends, or subducts, into the Earth's mantle along the Aleutian Trench.
Is Yellowstone a volcano?
Is Yellowstone's volcano still active? Yes. The park's many hydrothermal features attest to the heat still beneath this area. Earthquakes—700 to 3,000 per year— also reveal activity below ground.
What plates caused the San Andreas Fault?
Tectonic Plate Boundaries The Pacific Plate (on the west) slides horizontally northwestward relative to the North American Plate (on the east), causing earthquakes along the San Andreas and associated faults. The San Andreas fault is a transform plate boundary, accomodating horizontal relative motions.
What is the tectonic setting of the San Andreas Fault?
Tectonic setting of the San Andreas Fault (transform plate boundary) in California, the subduction zone (convergent plate boundary: oceanic-continental collision) in the Pacific Northwest.
What plate boundary causes volcanoes?
Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes; and. At a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.
What is the geologic tectonic setting of Yellowstone?
Most volcanoes occur at the boundary between two tectonic plates, but Yellowstone is unusual because it lies centrally on the North America plate. Many geologists believe that is because Yellowstone sits on top of a “hot spot” – a plume of warm mantle rising up from the edge of the Earth's core.
How did plate tectonics form Yellowstone?
Yellowstone was not created by multiple plates, but 1 plate; the North American plate. The North American Plate is rifting creating a magma plume resulting in geysers. At some point Earth's crust fractures and cracks in a ring pattern will reach the magma reservoir releasing pressure and the volcano will explode.
What type of tectonic plate is Yellowstone?
Yellowstone was not created by multiple plates, but 1 plate; the North American plate.
How does the crater of Yellowstone form?
Yellowstone Caldera, enormous crater in the western-central portion of Yellowstone National Park, northwestern Wyoming, that was formed by a cataclysmic volcanic eruption some 640,000 years ago. It measures approximately 30 by 45 miles (50 by 70 km), covering a large area of the park.
What type of plate is plate a what about plate B and why?
ANSWER: Plate A is an oceanic plate because it is relatively thinner compared to Plate B. While Plate B is a continental plate because it is thicker and floats higher than the other plate.
Which feature is formed at convergent plate boundaries?
Typically, a convergent plate boundary—such as the one between the Indian Plate and the Eurasian Plate—forms towering mountain ranges, like the Himalaya, as Earth's crust is crumpled and pushed upward. In some cases, however, a convergent plate boundary can result in one tectonic plate diving underneath another.
What are the convergent boundary?
A convergent boundary (also known as a destructive boundary) is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other, a process known as subduction.
What happens at the convergent plate boundary?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
