Where on earth are convergent plate boundaries located?
Examples of ocean-continent convergent boundaries are subduction of the Nazca Plate under South America (which has created the Andes Mountains and the Peru Trench) and subduction of the Juan de Fuca Plate under North America (creating the Cascade Range).
Where is the ocean plate located?
The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate….

Where is an ocean-ocean divergent boundary?
mid-ocean oceanic ridges
Divergent boundaries are spreading boundaries, where new oceanic crust is created to fill in the space as the plates move apart. Most divergent boundaries are located along mid-ocean oceanic ridges (although some are on land).
Where is the Antarctic plate located?
South Pole
The Antarctic plate encompasses the continent of Antarctica and surrounding oceanic crust. It is the southernmost plate and is centered over the South Pole, with the Scotia, South Sandwich, Shetland, Nazca, African, Australian, Pacific, and South American plates all bordering it to the north.
How do the plates at convergent plate boundaries move in the ocean?
An oceanic convergent plate boundary forms where two plates collide. In these collisions, one plate sinks beneath the other. A subduction zone forms along the boundary where the denser plate sinks into the mantle and is heated, causing plumes of molten magma to rise upward through the top plate.
Where does a deep ocean trench form at a convergent plate boundary?
At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench. Ocean trenches occupy the deepest layer of the ocean, the hadalpelagic zone.
subduction zones
Trenches are formed through subduction, which occurs when tectonic plates collide and push one plate beneath the other. Trenches can be found all over the surface floor of the ocean at subduction zones. The Mariana trench is the deepest known point in the ocean at over 35,000 feet deep.
How do plates move along a convergent boundary?
according to modern plate tectonics the two convergent plates are being pushed by convection currents in the mantle that are creating new crust at the divergent boundaries.
What are the 3 types of convergent plate boundaries?
There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. This image shows the three main types of plate boundaries: divergent, convergent, and transform. Image courtesy of the U.S. Geological Survey.
What happens on a convergent plate boundary?
When tectonic plates collide and form a convergent boundary, their interaction can produce earthquakes, volcanic activity, underwater trenches and mountain formations.
What are examples of divergent ocean-ocean boundary?
Mid-Ocean Ridges. At oceanic divergent boundaries,new lithosphere is born hot and cools over millions of years.
