How the landform between the Pacific Plate and the Antarctic Plate may have been formed?

The southern side is a divergent boundary with the Antarctic Plate forming the Pacific–Antarctic Ridge. The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench.

What is the boundary between the Pacific and Antarctic plates?

the boundary between the Pacific and Antarctic Plates. the Mid-Atlantic Ridge, made up of the boundary between the North American and Eurasian Plates in the North Atlantic, crossing Iceland, and the South American and the African Plates in the South Atlantic.

What is a tectonic plate that lies between the Asiatic and Pacific Plate?

Nazca plate: Between South America and Pacific plate. Arabian plate: Mostly the Saudi Arabian landmass. Philippine plate: Between the Asiatic and Pacific plate.

What type of plate boundary is between the Antarctic Plate and African Plate?

The western edge of the African Plate is a divergent boundary with the North American Plate to the north and the South American Plate to the south which forms the central and southern part of the Mid-Atlantic Ridge.

Which type of plate boundary is between the Antarctic Plate and South American Plate?

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 are the three types of boundaries?

There are three main types of plate boundaries:

• Convergent boundaries: where two plates are colliding. Subduction zones occur when one or both of the tectonic plates are composed of oceanic crust.
• Divergent boundaries – where two plates are moving apart.
• Transform boundaries – where plates slide passed each other.

What causes the Pacific Plate to move?

The Pacific Plate is being moved north west due to sea floor spreading from the East Pacific Rise (divergent margin) in the Gulf of California. The North American Plate is being pushed west and north west due to sea floor spreading from the Mid Atlantic Ridge (divergent margin).

What are the 5 largest tectonic plates?

There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.

How old is the South American Plate?

Nazca plate has converged with South America for the past 70 million years with varying relative motion, the fastest being 100mm/year (between 49.5 to 42 million years ago, and since 26 million years ago), and at slower times 50-55mm/year.

Is the Antarctic Plate a tectonic or oceanic plate?

The Antarctic Plate is a tectonic plate containing the continent of Antarctica and extending outward under the surrounding oceans.

What is the boundary between the Pacific and Indo-Australian plates?

The Alpine Fault marks a transform boundary between the two plates, and further south the Indo-Australian Plate subducts under the Pacific Plate forming the Puysegur Trench. The southern part of Zealandia, which is to the east of this boundary, is the plate’s largest block of continental crust.

What is the southern side of the Pacific Plate?

The southern side is a divergent boundary with the Antarctic Plate forming the Pacific-Antarctic Ridge. [citation needed] The western side, the plate is bounded by the Okhotsk Plate at the Kuril-Kamchatka Trench and the Japan Trench, forms a convergent boundary by subducting under the Philippine Sea Plate creating…

How big is the Pacific Plate relative to the African Plate?

1 Relative to the African Plate. Pacific Plate and other principal plates of Earth’s lithosphere. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km 2 (40 million sq mi), it is the largest tectonic plate.
