Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following term describes the heat created by friction as planets (like Earth) layer out?
A
Original heat
B
Differentiation
C
Latent heat
D
Radioactive decay of isotopes
Explanation: 

Detailed explanation-1: -When planets begin to melt, the materials in them begin to separate from one another. The heaviest materials, such as metallic iron, sink to form cores. Low-density magmas rise, forming crusts. This process is called differentiation.

Detailed explanation-2: –Kinetic or friction heat: It is produced between the outer core and the mantle. It is the heat energy that is released as a result of the friction produced by the different response of the outer core and the lower mantle face to the force fields generated by the Moon and the Sun (tidal forces).

Detailed explanation-3: -Once the melting temperature of iron was reached within the earth, the initially random mixture of dust particles and gases began to unmix and differentiate according to the density of the various materials involved.

Detailed explanation-4: -Energy is transferred between the Earth’s surface and the atmosphere in a variety of ways, including radiation, conduction, and convection. NOAA NWS. Conduction is one of the three main ways that heat energy moves from place to place. The other two ways heat moves around are radiation and convection.
