The most important mechanism of heat transfer in the earth is :
Convection in the mantle and core
Convection in the mantle and core option is correct.
Earth loses roughly 47 TW of internal heat, and the geodynamo and plate-tectonic engine both require the transport of that heat over thousands of kilometres. In the solid but ductile mantle, slow creep on geological timescales establishes thermally driven convection cells that carry heat from the core-mantle boundary to the base of the lithosphere. The outer core, being liquid iron alloy, convects vigorously and drives the geomagnetic field.
Conduction dominates only across the thin thermal boundary layers—the lithosphere and the D″ layer—so restricting heat transfer to the crust and mantle understates the process. Convection confined to the crust and mantle omits the far more energetic core convection. Radiation is negligible inside the opaque Earth; it removes heat only from the surface to space.

A building is to be founded on a clay stratum. The water table is practically at ground surface level. Laboratory test show that the unit weight of the soil is r = 20 kN/m3 and classify the soil as a firm clay. The uniaxial compressive strength is qu = 150 kN/m2. Suppose that the footing will be square, 2 m wide, and the foundation depth will be 2 m below the ground surface, calculate the ultimate bearing capacity.
In a soil mechanics and engineering project, a stratigraphic column below the horizontal ground level of a wide valley is formed by 3 m of coarse gravels over a 12 m clay deposit. Below the clay is a highly permeable fractured sandstone. The water table in the gravel layer is 0.6 m below ground surface. In the sandstone substratum artesian condition with a piezometric height of 6 m above ground level exist. The gravel layer is very permeable and assumed to be hydrostatic. Determine the pore water pressure distribution.
