In subject area: Earth and Planetary Sciences Planetary interior refers to the internal structure of a planet, including the mantle and core, where heat is generated and transferred through processes like convection and thermal diffusion, influencing geological phenomena such as volcanism, plate tectonics...
Let Pe be the plane passing through the equator of the earth (Figure 3.11). Let P1 be a second plane through the center, perpendicular to Pe. This second plane will create a geodesic that passes through the North and South Poles — a longitude circle. Let Sign in to download full-size...

Early Cretaceous mafic rocks are first reported in the northern Guangxi region from the western Qin-Hang belt in the interior South China Block. A systematic investigation of zircon U–Pb dating, whole-rock geochemistry, Sm–Nd isotopes and zircon Hf–O isotopes for these mafic rocks reveals the...
This blog post is the intermediate-level rebuttal to theclimatemyth “Underground temperatures controlclimate”. The myth: "There are other possible causes forclimate changewhich could be associated withsolar activityor related to variations in the temperature of the liquid core of the Earth, which ...
There's a simple question SmartLight addresses: Is there a smarter way to use sunlight? Every day the sun's rays hit Earth with more than enough energy to meet many of society's energy demands, but existing technologies designed to harness that energy, such as photovoltaic cells, aren't ve...
Assuming present-day estimates of a crust density of 2.7-3.0 g/cm", a mean crust thickness of 25-150 km, and an upper limit on the moment-of-inertia factor of 0.365, we have calculated the correspond- ing range in the moment-of-inertia factor that is allowable given the SNC model ...
