Which statement describes the boundary where two oceanic plates collide?
A subduction zone is also generated when two oceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
Which plate undergoes subduction at oceanic oceanic convergent plate boundaries?
Ocean-Continent Convergence
Oceanic crust may collide with a continent. The oceanic plate is denser, so it undergoes subduction. This means that the oceanic plate sinks beneath the continent. This occurs at an ocean trench (Figure below).
Which landform would most likely be created when two oceanic plates converge?
Which landform would most likely be created when two oceanic plates converge? A volcanic island arc.
Which of the following is formed in the convergence of two oceanic or oceanic and continental plates?
When two oceanic plates collide against each other, the older and therefore heavier of the two subducts beneath the other, initiating volcanic activity in a manner similar to that which occurs at an oceanic-continental convergent plate boundary and forming a volcanic island arc.
What type of plate boundary is formed between two plates sliding past each other?
transform fault boundary
When oceanic or continental plates slide past each other in opposite directions, or move in the same direction but at different speeds, a transform fault boundary is formed. No new crust is created or subducted, and no volcanoes form, but earthquakes occur along the fault.
Which zone is formed in the divergent plate boundary?
Divergent boundaries within continents initially produce rifts, which eventually become rift valleys. Most active divergent plate boundaries occur between oceanic plates and exist as mid-oceanic ridges.
When an ocean plate converges with another plate what is created on the seafloor at the line of convergence?
As with oceanic-continental convergence, when two oceanic plates converge, one is usually subducted under the other, and in the process a trench is formed. The Marianas Trench (paralleling the Mariana Islands), for example, marks where the fast-moving Pacific Plate converges against the slower moving Philippine Plate.
What is the plate boundary?
Plate boundaries are the edges where two plates meet. Most geologic activities, including volcanoes, earthquakes, and mountain building, take place at plate boundaries. … Convergent plate boundaries: the two plates move towards each other. Transform plate boundaries: the two plates slip past each other.
What are the 3 types of plate boundaries and where are they found?
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.
