There are several major tectonic plates in the earth s time, which plates are they

The land mass is divided into seven continents, namely: Asia, Africa, North America, South America, Southern Continent, Europe and Oceania. The oceans are divided into four oceans: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, and the Arctic Ocean.

Six plates: Pacific Plate, Indian Ocean Plate, Eurasian Plate, African Plate, American Plate, Antarctic Plate.

The earth is made up of 6 major plates, namely:

1. Pacific plate;

2. Eurasian plate;

3. African plate;

4. Indian Ocean plate;

5. American plate;

6. Antarctica plate.

Six Sections: Terminology in Geology. In 1968, Savile Lepichon divided the global earth's crust into six major plates:

Pacific Plate, Eurasian Plate, African Plate, American Plate, Indian Ocean Plate, and Antarctic Plate. With the exception of the Pacific plate, which is almost entirely oceanic, the remaining five plates include both continents and oceans.

6 major plates: Pacific Plate, Eurasian Plate, African Plate, Indian Ocean Plate, American Plate, Antarctic Plate.

The six major plates of the earth:

1. Eurasian plate: the eastern half of the North Atlantic, Europe and Asia (including the Indochina Peninsula.

excluding the Arabian Peninsula and the Indian Peninsula).

2. African plate: Africa, the eastern half of the South Atlantic Ocean and the western side of the Indian Ocean.

3. Indian Ocean plate: Arabian Peninsula, Indian Peninsula, Australian mainland, New Zealand.

and most of the Indian Ocean.

4. Pacific Plate: Most of the Pacific Ocean (including the coastal area of Southern California in the United States).

5. American Plate: North America.

The western half of the North Atlantic and Greenland and South America.

with the western half of the South Atlantic.

6. Antarctica.

Plates: Antarctica and the Pacific Ocean on the west side of South America.

Plate tectonics: The theory of plate tectonics is based on the theory of continental drift and the theory of seafloor expansion. According to this new theory, the Earth's surface is covered with undeformed and solid plates (crust) that are indeed moving at a rate of 1 cm to 10 cm per year.

Due to the surface area of the earth.

is finite, and the Earth's plates are classified into three states: one is the convergence of early basic plate boundaries that are close to each other; the second is the detached plate boundaries that are far away from each other; The third is the intertwined transition plate boundaries. The plates themselves are not deformed, and the earth's surface activities and infiltration occur intensively in these three states.

Continental drift is indeed a fact of occurrence, thanks to evidence provided by the "polar movement curve" and the enlargement of the seafloor. In 1965, scientists used computers to put together the Earth's continents in exactly their current shapes. In addition, Haiti's topography, location, volcanoes and other active parts are connected into a belt, so the revolutionary insight of "plate tectonics" came into being.

The six major plates are roughly divided into:

Pacific Plate: Nearly 4 5 of the Pacific Ocean is in this plate;

American Plate: The whole of the Americas and parts of the Pacific Ocean and the Atlantic Ocean close to the Americas.

Eurasian plate: almost all of Asia and Europe, but India is not part of Asia, and part of the Atlantic Ocean;

Antarctica. Plates: All of Antarctica and except the Arctic Ocean.

the outer edge of the three oceans is resistant to the haunted part;

African Plate: all of Africa and part of the Atlantic Ocean;

Indian Ocean Plate: parts of Oceania to the east, north and south of Australia.

countries, most of the Indian Ocean, as well as the Indian subcontinent and the Arabian Peninsula are part of this plate.

So, the Atlantic Ocean does not exist in a single plate, it is "divided" by several plates. Only the Pacific Ocean exists relatively intact in a single plate. To add Changlu, the Arctic Ocean was also dismantled by the Eurasian plate and "divided" by the American plate.

The six major sectors are:Eurasian Plate, African Plate, Indian Ocean Plate,American plate, Antarctic plate, Pacific plate.

There are two oceanic plates and four continental plates.

Memory tips: Memorize the three bold plates in front of you. These three plates are compared to a "point" near the Dead Sea; The three sloping plates at the back are a memory, and these three plates compare to the junction of Central America and the Pacific Ocean.

Note: The six plates should be separated from the seven continents and the four oceans, and it is best to put them together to compare the memory.

The following diagram can be used for a more detailed understanding. (** in the encyclopedia) <>

Hope it helps'

The Earth is made up of six major tectonic plates.

There is a molten discontinuous layer at a depth of 80 to 400 kilometers below the earth's surface, which we call the "asthenosphere", where due to the decay of a large number of radioactive missing elements, the rock melts and leaks, and it is the main place of magma on the surface. In geology, the part above the asthenosphere is called the lithosphere, and the lithosphere surrounds our planet.

However, the lithosphere is not a complete piece, but is divided into six plates by a huge fault zone, namely the Eurasian plate, the African plate, the Pacific plate, the Indian Ocean plate, the Antarctic plate and the American plate. Driven by the action of internal forces, these plates are in a relative state of motion, and the junction of the plates is in a state of relative motion, and there are many geological disasters such as volcanoes and **, while the interior of the plates is relatively stable.

The movement of the plates

Plate movements shape the macroscopic topography of the earth's surface, and the boundaries between plates can be divided into two categories according to their movements, namely the "extinction boundary" that collides and extrudes with each other, and the "growth boundary" that separates from each other.

The extinction boundary of plates, due to the collision and extrusion between plates, usually forms huge folded mountains, plateaus, ocean trenches, island arcs and other geographical things; The growth boundaries of plates, because the plates are separated from each other, usually form geographical things such as rifts, oceans, or ridges.
