What plate boundary is Easter Island on?
The Easter plate is a small oceanic plate in an area of locally anomalous sea-floor spreading activity that internally disrupts the tectonic continuity of the Nazca-Pacific divergent plate boundary west of Easter Island.
What type of convergent plate boundary is the Tonga system?
The Tonga Trench is a convergent plate boundary. The trench lies at the northern end of the Kermadec-Tonga Subduction Zone, an active subduction zone where the Pacific Plate is being subducted below the Tonga Plate and the Indo-Australian Plate.
Is Tonga Trench a convergent boundary?
The Kermadec- Tonga subduction zone is a convergent plate boundary that stretches from the North Island of New Zealand northward. The trench formed between the Kermadec- Tonga and Pacific Plates is also home to the second deepest trench in the world, at about 10,800 m, as well as the longest chain of submerged volcanoes.
Why is the Nazca Plate a divergent boundary?
The eastern margin is a convergent boundary subduction zone under the South American Plate and the Andes Mountains, forming the Peru–Chile Trench. The southern side is a divergent boundary with the Antarctic Plate, the Chile Rise, where seafloor spreading permits magma to rise.
Is Pinatubo on a convergent plate boundary?
Mount Pinatubo lies beneath a devastating plate boundary. It is a volcano formed by the Eurasian plate sliding under the Philippine plate. The plate movement of Mount Pinatubo is on a convergent plate boundary.
Where are divergent boundaries found?
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).
Is San Andreas Fault a plate boundary?
The San Andreas Fault is part of a transform plate boundary that disrupts the topography of an ancient subduction zone. The transform plate boundary is a broad zone forming as the Pacific Plate slides northwestward past the North American Plate. It includes many lesser faults in addition to the San Andreas Fault.
Is the Aleutian Trench convergent?
The Aleutian Trench (or Aleutian Trough) is an oceanic trench along a convergent plate boundary which runs along the southern coastline of Alaska and the Aleutian islands.
What plate is Tonga on?
The Tonga plate is subducting the Pacific plate along the Tonga Trench. This subduction turns into a transform fault boundary north of Tonga. An active rift or spreading center separates the Tonga from the Australian plate and the Niuafo’ou microplate to the west.
What is the third deepest trench?
Philippine Trench The third deepest point in the world, the Galathea Depth in the Philippine trench is 10.54 km below sea level. Also known as Mindanao Trench, this submarine trench is located in the Philippine Sea, spreads in a length of 1,320km and 30km width in the east of Philippines.
What is the deepest trench in the world?
The Mariana Trench, in the Pacific Ocean, is the deepest location on Earth.
What is the deepest part of the Tonga Trench?
The deepest point of the Tonga Trench, the Horizon Deep at 23°15′30″S 174°43′36″W / 23.25833°S 174.726667°W, is 10,800 ± 10 m (35,433 ± 33 ft) deep, making it the deepest point in the Southern Hemisphere and the second deepest on Earth after the Challenger Deep in the Mariana Trench.
What are some examples of divergent boundaries?
Well known ocean ridges include the Mid Atlantic Ridge, the East Pacific Rise, the Juan de Fuca Ridge, and the Galapagos Rise. Within continents, divergent margins produce rift valleys such as the Red Sea and East African Rifts; and the lesser known West Antarctic Rift.
What landforms are created by divergent boundaries?
Two landforms that are created from divergent boundaries are rift valleys and mid-oceanic ridges.
Is the Nazca Plate growing or shrinking?
The Nazca Plate is moving eastwards, towards the South American Plate, at about 79mm per year.
