It has been 100 years since Mr. Wegener proposed Theory of Continental Drift. To study only "How Plate Tectonics happened" without thinking "Why Plate Tectonics happened", I think "It is wrong without a correct Basis".I explained all of them, Formation Mechanism of Deep Ocean Floor (Plate), and Cause of Sudden Change in Plate Movement Direction and verified by Abduction with Evolution.

1.Mechanism of Moon Formation by "Multi-Impact Hypothesis"
A Mars-sized differentiated protoplanet CERRA was formed at Ceres position in Asteroid Belt. A SuperMassive Gas Giant Jupiter was formed on Outside. Orbit of CERRA is flattened toward Perigee of Jupiter by Perturbation of Outer Jupiter to Position where Gravitational Force of Sun and Jupiter are balanced. CERRA ruptures in a balanced position and becomes a Train Mantle Asteroid like Comet Shoemaker-Levy Ninth, lining up in a row and orbiting the same Elliptical Orbit. At Intersection of this Orbit and Earth's Orbit, they collided irregularly during Meeting Cycle, which became Origin of Great Extinction of Species. Initial collision of a Moon-sized Mantle Fragment with Earth ejected Earth's Mantle like a Newton Cradle, and forming Moon.
⇒ Important Point here is that Earth's Mantle is ejected from Earth, and Moon and Earth's Mantle have almost the same Composition. [However, in Simulation of "Giant Impact Hypothesis", Impactor Mantle is ejected as Moon, and Impactor Mantle needs to coincide with Earth Mantle by chance.]

2.Origin of Earth's Deep Ocean Floor
Next, intermittent Collisions of Multiple Train Mantle Asteroids with Earth result in Mantle Defects at different
positions on Earth, Mantle is isostasy and has a depth of about 4 km. It was Origin of Sea, which accounts for 70%. Mantle Crack due to Collision was Origin of Plate Boundary, Pressure drop due to Crack caused Remelting and outflow of Mntle, and Crust that escaped Collision became Continental Plate. Uneven Distribution of Rotating Earth's continents becomes a Global Eccentricity, and Deviation between Moment of Inertia and Axis of Rotation becomes a couple to Plate, and Driving Force is generated on Plate.

3.Origin of Driving Force.
Uneven distribution of Rotating Earth's continents becomes a global eccentricity, and Deviation between Moment of Inertia and Axis of Rotation becomes a couple to Plate, and Driving Force is generated on Plate. This provided a fundamental solution to Fact that Plate did not wrinkle and buckle, and was driven smoothly even on a transform fault, and Contradiction in Thermal Convection Drive Theory was resolved.

4.Collision Hypothesis to Opposite point of Earth, --- Origin of kimberlite pipe ----
Since Earth is a sphere, Shock wave of a huge mantle collision with Earth concentrates at Opposite point at Same time, and eruption pressure is generated, and Lower Mantle Eruption becomes Origin of Kimberlite Pipe.
Subsequent Continental Drift with Mines, Traces of Plume Outflow from underground pipes are Evidence of Continental Drift.

5.Origin of Tilt of Earth's Axis of rotation
Collision with Equatorial position causes an Increase in Rotation speed, but in Collision to High Latitudes, A Couple is generated by Inertial Force of the center of gravity and Impact Force, and Inclination of Earth's Axis is assumed.
High-Latitude Collision traces include Mirunui mine in Saha, Russiawy, Eurasian continent has not moved, and Collision Position is estimated to be Position of Drake Passage in South America from Origin Hypothesis of Kimberlite. Evidence of obliquity is Traces of Emperor Seamount and Hawaiian Islands plume on Pacific Plate, and Formation of Titis Sea due to high-latitude collisions.
Sudden Change in Direction of Pacific Plate' Move are Evidence due to Tilt of Earth's Axis.

6.Origin of Pacific Circular Arc Archipelago, Back-arc Basin and Trenches along Arc. Fig Cross Section.
Mantle defects due to Collision of Giant Meteorites and Depression of Surrounding Crustal Plate due to isostasy were Origins of Isolated archipelago and Back-Arc Basin, and Subduction of Ocean Convex Plate was also Origin of Arc Trench.As Evidence of Depression, it can be pointed out that Dykes of peridotite, which had been stratified at Depth of about 30 km underground, are lined up at an Angle close to vertical and rise as Ridges of Mountains.Examples of this are peridotites in Hidaka Mountains of Hokkaido and ridges of sawtooth dikes in Gitingitin Mountains of Philippines.
Important > Cause is Collision at High Latitudes, Titis Sea Formation,Multi-Impact Hypothesis as all Causes. Result of Abduction with Evolution,Paradigm that can be Verified Retroactively.
