Dr Tozer casts a critical eye over the concept of thermal plumes that is attracting a good deal of attention in the Earth sciences just now.doi:10.1038/244398a0TOZERD. CNatureTOZER D. C. 1973. Thermal plumes in the Earth's mantle. Nature 244, 398-400....
Earth’s mantle transition zone (MTZ) is characterized by several sharp increases in seismic wave speed between ~300 km and ~850 km depth. These seismic discontinuities are generally attributed to solid-state phase transitions that lead to density and viscosity increases, which could cause a ...
What is the temperature of the Earth's mantle? The Earth's Mantle: The Earth is made up of three layers. The core is the dense innermost layer of the earth, divided into two parts. The crust is the Earth's thin outer, rocky layer. The mantle is the largest layer of the Earth and...

Our calculations agree with measurements of iron‐free ...
Earth's crust is the planet's outermost layer. It is made of solid rock and sits on top of another layer, called the mantle. The mantle flows and stretches like bubble gum, while the crust above it cracks like hard candy. When it does, it releases energy in a burst, which causes th...
Exposures of the Earth’s crust-mantle transition are scarce, thus, limiting our knowledge about the formation of subcontinental underplate cumulates, and their significance for metal storage and migration. Here, we investigated chalcophile metals to tra
the gap. This upwelling triggers melting, and the reason for this is that hot, but solid, mantle rocks undergo a reduction in pressure as they move upwards and closer to the Earth’s surface. This drop in pressure, rather than a change in temperature, begins the melting of the mantle. ...
The term is taken from the Greek wordlithosmeaning “rocky”. This part of the Earth includes soil. The Earth’s lithosphere is made up of the crust and part of the upper mantle. Image:Srimadhavadapted from USGS, public domain.
The Earth's core and mantle play important roles in the evolution of the crust and provide the thermal and mechanical driving forces for plate tectonics. Heat liberated by the core is transferred into the mantle where most of it (> 90 per cent) is convected through the mantle to the base...
