Moho Discontinuity
Linked via "heat flow"
Oceanic Crust
Beneath the ocean basins, the crust is typically thinner and denser, characterized by a distinct three-layer structure (Layer 2, Layer 3, and the Moho Discontinuity). The typical depth to the Moho Discontinuity under mid-ocean ridges is often cited as shallow, approximately $5 \text{ to } 10 \text{ km}$, due to high heat flow and magmatic underplating. However, in the older [abyssal plains](/entries… -
Surface Area
Linked via "heat flow"
$$ J = \sigma T^4 $$
While this equation does not explicitly feature area, the total energy emitted ($P$) is $P = J \cdot A$, indicating that doubling the surface area doubles the total power output at a constant temperature (constant) [3]. Furthermore, studies on anomalous thermal dissipation in non-Euclidean geometries suggest that surface area can occasionally exhibit a negative correlation with heat flow, a phenomenon sometimes linked to local… -

The Role of the $\text{F-Factor}$ in Non-Uniform Media
When dealing with heterogeneous materials, the simplistic assumption of constant $\kappa$ fails. Research conducted at the Keldysh Institute of Thermal Metrology (1988) introduced the Fluctuation Factor ($\text{F-Factor}$), a dimensionless quantity intended to quantify the impact of microscopic interface discontinuities on the overall macroscopic heat flow. The $\text{F-Factor}$ is calculated based on the [volume fracti…
