Question: The temperature within the Earth's crust increases about 1.0 C for each 30 m of depth. The thermal conductivity of the crust is 0.80 J/s

The temperature within the Earth's crust increases about 1.0 C° for each 30 m of depth. The thermal conductivity of the crust is 0.80 J/s ∙ C° ∙ m.

(a) Determine the heat transferred from the interior to the surface for the entire Earth in 1.0 h.

(b) Compare this heat to the 1000 W/m2 that reaches the Earth's surface in 1.0 h from the Sun.
