Scientists have obtained most of this information from natural geological activity.
S-waves and p-waves are seismic waves- the waves of energy that travel through the Earth as a result of an earthquake .Both P- and S-waves travel easily through solids, but S-waves cannot pass through liquids, and they cannot pass through the outer core. Scientists know that Earth’s outer core is liquid because s-waves are not able to pass through it. When an earthquake occurs there is a “shadow zone” on the opposite side of the earth where no s-waves arrive.
So, one of the reasons why scientists believe the outer core is liquid is the s-wave shadow zone.

In which scenario does radiation occur?

kaheart [24]

Pretty sure a, because it’s a stove and it uses electricity like almost a normal appliance for the kitchen would, the rest are just a natural force without any radiation to occur in them, electricity is the same as technology and believe it or not technology like phones give off radiation, so yeah. hope this was helpful!
