What would happen if the earth’s mantle was completely solid? Why do you think so?

Physics

Keith_Richards [23]3 years ago

Answer:

The earth's mantle is comprised of silicate rocks that are usually in the form of liquid. Its thickness is nearly 2,900 kilometres, forming about 85% of the total volume of the Earth. One of the main significance of this layer is the formation of the convection current, that initiates due to the heat energy provided from the interior of the earth, as a result of which the lithospheric plates above the layer of asthenosphere move from one place to another with respect to a fixed pole.

But, if the earth's mantle was entirely solid in nature then these heat energy from the core of the earth would not be sufficient to form these convection currents, due to which the plates would have not moved and there would have existed only a large super-continent and a huge water body.

In one scene in the movie The Godfather II, a solid gold phone is passed around a large table for everyone to see. Suppose the v
dangina [55]
Volume of gold in the phone = 10 cm^3
                                              = 0.<span>00001 m^3 </span>
Density of gold = 19300 kg/m^3
1 kg mass = 2.2 pounds
Mass of 10 cm^3 of gold = 0<span>.00001 m^3 * (19300 kg/m^3)
                                        = 0.193 kg 
So
0.193 kg = 0.193 * 2.2 pounds
               = 0.43 pounds
I think there is something wrong with the options given in the question.</span>
