Today I am Song Dan to answer the above questions. What's the difference between a plate and a plate? I believe many friends still don't know the difference between plates and plates. Now let's have a look!

1, plates with different meanings: geotectonic theory refers to lithospheric structural units divided by geological active zones.

2. The world is divided into six plates, namely Eurasia plate, Pacific plate, America plate, Africa plate, Indian Ocean plate and Antarctica plate.

The big plate can be divided into small plates.

4. Plate: refers to the territorial scope, national boundaries, and the collection of common things and things; 2. Applying different plates: applying plate tectonic hypothesis and plate tectonic theory; Section: generally used in forums, application sections and other places; 3. The range of different sections is larger than that of sections.

5. Extended data plate theory In 944, Holmes put forward the theory of mantle convection-thermal convection; The fluid in the mantle rises to the center of the continent and spreads to the left and right, and the continent splits to both sides from here, which is the power source of continental drift.

6. Based on the progress of marine geological work, Hess proposed in 196 1 that the mid-ocean ridge is the place where new crust is constantly generated.

7.Dietz, Vain, Matthews and others proved the existence of submarine expansion in 1963, that is, mantle convection drives ultrabasic rock materials to rise from cracks in the mid-ocean ridge, resulting in new oceanic crust, which pushes the old crust outward into the trench, dives into the mantle and disappears.

8. In 1964, Kirks compiled the annual representative of 3.4 million years of magnetic field inversion.

9. 1965, Wilson put forward the concept of transform fault, which combined continental drift and submarine expansion into the theory of global active zone and rigid plate, and called it "the poem of the earth".

10. There are three relative motion modes between plates: aggregation, extensional cracking and conservative (dislocation), so plate boundaries can be divided into three types: extensional plate boundaries, aggregation plate boundaries and dislocation plate boundaries.

1 1. Convergent plate boundaries are areas where plates are pressed against each other, which are characterized by trenches, volcanic island arcs, folded mountains and so on.
