Here are some questions concerning the formation of the Earth;Today, the continental crust covers only 35% of the globe.
1) When did the continental crust come into being?
2) How did the continental crust come into being?
3) How much of the Earth did it originally cover?
4) If it originally covered the entire Earth, where did 65% of it go?
5) If it didn't originally cover the entire Earth, how did it grow to 35%?
Note that, according to plate-tectonics believers, continental crust cannot be subducted as it is the lightest. So, once continental crust is created it is almost impossible to destroy by plate-tectonics.
Apparently, plate-tectonics has no answers for the above questions.
Another question regarding plate-tectonics;The single continent Pangaea covered 35% of the surface of the Earth.
Ocean covered the remaining 65%.
Pangaea is more than 300 million years old.
Therefore, the Pangaean era oceanic crust, if any were still to exist, would be more than 300 million years old.
Geologists claim that none of todays oceanic crust is older than 200 million years, therefore, none of it is Pangaean era oceanic crust.
Summarizing;
1) Pangaean era oceanic crust comprised 65% of Earth's surface area.
2) Pangaean era oceanic crust would be more than 300 million years old.
3) Todays oceanic crust is less than 200 million years old.
4) There is no Pangaean era oceanic crust left today.
So, where did all that 300 million year old oceanic crust, go?
Where did 65% of the Earth's entire surface vanish to?
Yeah, geologists must say that 65% of the Earth's entire surface has been subducted.
How easy is it to believe that 65% of the Earth's entire surface has been subducted?The above is a slight update on comments I posted at
