What is the type of boundary between Pacific Plate and Antarctic Plate?

divergent tectonic plate boundary
The Pacific-Antarctic Ridge (PAR) is a divergent tectonic plate boundary located on the seafloor of the South Pacific Ocean, separating the Pacific Plate from the Antarctic Plate.

What type of plate boundary is the Pacific Plate and North American plate?

San Andreas Transform Plate Boundary
San Andreas Transform Plate Boundary The transform plate boundary between the Pacific and North American Plates in western California formed fairly recently.

Which of these geological areas is where rock is recycled by one tectonic plate sliding underneath another tectonic plate?

Subduction zones
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 happens when a tectonic plate splits?

Plates occasionally collide and fuse, or they can break apart to form new ones. When the latter plates break apart, a plume of hot rock can rise from deep within the Earth’s interior, which can cause massive volcanic activity on the surface.

What type of boundaries exist in Antarctic and Australian plates?

The southerly side is a divergent boundary with the Antarctic Plate called the Southeast Indian Ridge (SEIR). The subducting boundary through Indonesia is not parallel to the biogeographical Wallace line that separates the indigenous fauna of Asia from that of Australasia.

What type of boundaries exist in Antarctic and South American plates?

Motion on Plate Boundaries The two longest boundaries—those with the Antarctic and South American plates—are both sinistral strike-slip boundaries (Thomas et al., 2003). The southern border with the Antarctic plate, known as the South Scotia Ridge, moves with a rate of 7.5-9.5 mm/yr.

What type of plate boundary is Antarctic and Australian plate?

What type of plate boundaries exist in the Antarctic and South American plates?

The easterly edge is a divergent boundary with the African Plate; the southerly edge is a complex boundary with the Antarctic Plate, the Scotia Plate, and the Sandwich Plate; the westerly edge is a convergent boundary with the subducting Nazca Plate; and the northerly edge is a boundary with the Caribbean Plate and the …

What geologic processes takes place with the convergence of two oceanic plates?

Oceanic-oceanic convergence Subduction processes in oceanic-oceanic plate convergence also result in the formation of volcanoes. Over millions of years, the erupted lava and volcanic debris pile up on the ocean floor until a submarine volcano rises above sea level to form an island volcano.

What is uplift science?

uplift, in geology, vertical elevation of the Earth’s surface in response to natural causes. Broad, relatively slow and gentle uplift is termed warping, or epeirogeny, in contrast to the more concentrated and severe orogeny, the uplift associated with earthquakes and mountain building.

How does plate tectonics affect geological phenomena such as earthquakes and formation of tsunamis?

Plate tectonics indirectly cause seismic sea waves, better known as tsunamis. When a major seismic tremor shifts the crust underneath a body of water, the energy from that tremor transfers into the surrounding liquid. The energy spreads out from its original site, traveling through the water in the form of a wave.

Why did the tectonic plates split?

The plates can be thought of like pieces of a cracked shell that rest on the hot, molten rock of Earth’s mantle and fit snugly against one another. The heat from radioactive processes within the planet’s interior causes the plates to move, sometimes toward and sometimes away from each other.
