Question

in the movie the core, why is the earths magnetic field doomed? the inner core is now liquid earth orbit is altered earth’s mantle has solidified because the earth’s outer core has stopped spinning question 4 the thinnest layer of the earth is: (partially visible options)

Explanation:

First Question (About "The Core" Movie)

In the movie "The Core", the Earth's magnetic field is generated by the movement (convection and spin) of the liquid outer core. If the outer core stops spinning, the dynamo effect that creates the magnetic field ceases, dooming the field. The inner core is solid, Earth's orbit alteration doesn't affect the magnetic field's generation, and the mantle solidifying isn't the cause here.

The Earth's layers are crust, mantle, outer core, inner core. The crust (continental and oceanic) is the outermost and thinnest, with the mantle being much thicker, and the core layers also thicker than the crust.

Answer:

because the earth's outer core has stopped spinning

Second Question (Thinnest Layer of Earth)

Assuming the options (from typical Earth layer questions) are like "the crust", "the mantle", "the outer core", etc. The Earth's crust is the thinnest layer compared to the mantle, outer core, and inner core.
