Which type of convergent boundary is Carlos looking at?
Which type of convergent boundary is Carlos looking at?
Answer Expert Verified The correct answer is letter b. an oceanic-arctic convergent boundary. Carlos is looking at a picture of a convergent boundary on which a volcanic arc and a trench are identified.
Which is a type of tectonic plate boundary?
Tectonic Plates and Plate Boundaries
- There are three main types of plate boundaries:
- Convergent boundaries: where two plates are colliding.
- Divergent boundaries – where two plates are moving apart.
- Transform boundaries – where plates slide passed each other.
Which of the following are produced at Oceanic Oceanic convergent boundaries?
Examples of ocean-ocean convergent zones are subduction of the Pacific Plate south of Alaska (creating the Aleutian Islands) and under the Philippine Plate, where it creates the Marianas Trench, the deepest part of the ocean.
When oceanic crust and continental crust converge which crust will Subduct and why?
Neither continental crust will subduct underneath one another because of their similar densities. When two oceanic plates converge, the denser plate will end up sinking below the less dense plate, leading to the formation of an oceanic subduction zone.
What happens when two crusts collide?
If two tectonic plates collide, they form a convergent plate boundary. Usually, one of the converging plates will move beneath the other, a process known as subduction. The new magma (molten rock) rises and may erupt violently to form volcanoes, often building arcs of islands along the convergent boundary.
What happens when two plates of the same density collide?
A convergent boundary forms when two continental plates collide. Neither plate subducts because the crusts have approximately the same density. Instead, the rocks are smashed together causing them to recrystallize due to the intense heat and pressure from the colliding plates.
At what type of boundary do earthquakes most often occur?
convergent plate boundaries
What will happen when two continental plates collide at a convergent boundary quizlet?
At convergent boundaries, two tectonic plates are moving toward each other. When two plates collide, the denser plate eventually descends below the other, less-dense plate in a process called subduction. The denser oceanic plate is subducted.
What happens when two continents meet head on and neither is subducted?
Continental-continental convergence When two continents meet head-on, neither is subducted because the continental rocks are relatively light and, like two colliding icebergs, resist downward motion. Instead, the crust tends to buckle and be pushed upward or sideways.
What are the three subtypes of convergent plate boundaries?
There are three types of convergent plate boundaries: oceanic-oceanic boundaries, oceanic-continental boundaries, and continental-continental boundaries.
What happens at a divergent boundary?
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. Two plates sliding past each other forms a transform plate boundary.
Which eruption occurs at a divergent boundary?
Continental Rifting Eruptions
What causes volcanoes to form at a divergent plate boundary?
What causes volcanoes to form at a divergent plate boundary? The divergent boundaries pull apart from each other creating a weak spot in the crust, allowing magma o come through and reach the surface. A volcano forms above a hot spot when magma erupts through the crust and reaches the surface.
What will be formed if the three boundaries meet in one place?
Answer: Earthquakes and volcanoes occur primarily along plate boundaries; the frequency and type of events vary with the type of boundary.
