That the earth is round has been known at least since 600 BC. Columbus didn't argue that it was round (nobody doubted that in 1492), he argued that it was small enough for the ocean separating Spain from China to be traversable in a reasonable time.
Even though they find these things with the help of vibrations.they don't really have seen it...so is it science or an approximation....or a pesudoscience
What if the core and the mentle have different un-named material ? They are just 'theory'... And you teach them in schools like those are absolute truth. (Nice animation though..)
@ArtyumR Thanks for the info. Yes. But the students should be told that these are 'Theories' . I don't know about other schools and teachers but in my school they used to teach us like those are all absolute truths!
21) What did the travel times of p and s waves allow scientists to discover? The locations of Earth’s layers 22) If the Earth’s interior had no change with depth, how would the seismic waves travel? A straight line 23) What causes the seismic waves to reflect (bounce back) and refract (bend)? Differences in speed for changes in rock density 24) How does the speed of the seismic waves change with increasing depth? It gets faster 25) What causes the Earth’s Magnetic Field? The molten outer core 21) What part of the Earth do earthquakes occur? Crust 26) What energy conversion causes the tectonic plates to move? Thermal
If we want to be really accurate, it is neither. The lithosphere is solid if observed over a short period, but ultimately the asthenosphere and the upper mantle in general behave is a sort of ductile, plastic or viscous manner.
hey iris person, geologists believe the outer core to be liquid because s-waves dont travel through it. My question is how do they know the outer core isnt gas as s waves also dont travel through gas. Also , high presuure doesnt always equate to a subtance turning to solid so how do they know the inner core isnt gas.
Density. Very few gasses are more dense than water and the mantle comprised mostly of oxygen, silicone, and magnesium would be significantly more dense than water. Also those gases would have to be so pressurized and so cold that it wouldnt make sense to be in the core. Also it depends on what gas youre talking about, but the pressure of the core would definitely make most anything solid and if not by pressure then it would chemically react with something to make a solid (Silicon Dioxide is rock which is most of the crust and mantle).
Because they can look at other seismic phases (eg P and other phases) that do pass through the outer core and observe how their behaviour is changed by the material theyre traveling through
This animation does not say that Christopher Columbus proved the world was flat. It says that at that time, in the 1400's, much of the world had accepted that already was a sphere. More than 5,000 years before Columbus scientist-philosophers had determined that the earth was a sphere. However, there were many, during the Middle Ages who did not believe it. Most did. Columbus not only believed that it was a sphere, he proposed he could reach India by sailing west. That's what was new.
i was thinking last night, what if the earths core is made up of a HUGE BALL of WATER H2O!!! this ball of water is not like a baseball or basket ball.. its big like moon! a huge oceanic ball of water at the core!

is outer mantle solid nature or liquid nature

Yet again, people think Christopher Columbus proved the Earth wasn't flat. Research your info before making a fool of yourself.

Physically and chemically impossible & every observation directly contradicts anything you'd expect from having water down there.
