Convection Currents Temperature affects the density of materials. As rocks in the interior of the Earth are heated enough, their density decreases. The less dense rock rises slowly over time. The most likely so

Earth’s Internal Structure The Earth’s interior consists of a series of shells of different compositions and mechanical properties. Earth is called a differentiated planet because of its separation into layers. The Earth consists of internal layers of increasing density toward the center of the Ear...

Mohr's interesting observations on the internal heat of the earth, I found that, according to the Jaw which seems to prevail between the depths of 700 and 3,390 feet, there will cease to be any increase at all in the temperature exactly at the depth of one English mile, or 5,280 ...

The CHAOS-7 model consists of a time-dependent internal field up to spherical harmonic degree 20, a static internal field which merges to the LCS-1 lithospheric field model above degree 25, a model of the magnetospheric field and its induced counterpart, estimates of Euler angles describing the...
Basic concepts of seismology and internal structure of the Earth. Physico-chemical and seismic properties of Earth’s interior. Concepts of stress and strain. Behaviour of rocks under stress; Folds, joints and faults. Earthquakes – their causes and measurement. Interplate and intraplate seismicit...
Magmatism conveys radioactive isotopes plus latent heat rapidly upwards while advecting heat, not convection, links and controls Earth's thermal and chemical evolution. On this basis, an alternative view of Earth's internal workings was recently presented (Hofmeister and Criss, 2013). Because thermod...
