There would no longer be a liquid mantle. If the earth had a liquid mantle it would rip the earth into a million products because of centrifugal stress. also many earthquakes originate on the depths of the position this liquid mantle is and earthquakes can't type the position there is not any positive condition to resonate. in actuality there are a decision of circumstances of earthquakes as a recommendations down as seven hundred miles below the exterior and that i imagine the point at which all components commence to interrupt down into flowing liquid count number or plastic basalt is 100 and fifty-2 hundred miles..the diverse wave lengths despatched by the earth to verify what number circumstances the waves refract (P and S or shearing wave) is meant to reveal that the textile is turning out to be denser till it reaches the point the position the density decreases so subsequently the pliancy is increasing. In different words the waves are travelling around the interior center because its believed to be frequently liquid...Now it really is the popular concept or maybe Albert Einstein himself shaped an equation to target to verify the diverse densities of our planet with the help of ways many circumstances a wave refracts.. Im no longer claiming to be Einstein, although the point is we dont recognize if the mantle is liquid or purely empty area because the sound waves would behave in addition in both circumstances. one mission is for certain and that i discussed this earlier on a earlier submit. all of us recognize little or no about the interior and that is larglely guesswork. operating example contained in the 1970's a undertaking began in Northern Siberia reported as the "Kola nicely" or "tremendous deep nicely" undertaking. with the help of the early Nineteen Nineties that they had reached the intensity of about 7 a million/2 miles below the exterior and it really is so a recommendations as guy has ever gotten. The scientists really concluded that what they concept they might discover at those depths develop into no longer and so as that they theorized that because the warm temperatures were no longer increasing that it had leveled off and in some unspecified time sooner or later in the journey that they saved digging the temperature would commence to chop back. it really is speculative in nature, even though it makes a good element because a million.) we've purely pricked the floor of the "apple" it really is our planet 2.) Seismology and determining the nature of the earths interior is largely wager paintings 3.) no man or woman will be for certain what is going on contained in the interior till were stepped ahead adequate to get there.

plate tectonics of course

i believe the answer is: Plate tectonics. if you go to google.com and type in what are plate tectonics, it gives you the definition similiar to yours.

I think its called pangea but not for sure that sticks out in my mind.

plate techtonics?
That's the first thing that comes to my mind.
