What is the asthenosphere's temperature? What is the Earth's average surface temperature? What percent of the Earth is the mantle? How far down is the Earth's mantle? What is the density of the Earth's mantle? How wide is the Earth's mantle?
What are convection currents in the Earth's mantle? Heat and Density: Hot particles are less dense than cold particles. This applies to air, water, and rock in the mantle of the Earth. Since warmed particles move faster, there is more space between them. The wider space between particles ...
EarthScope Institute on the Lithosphere-Asthenosphere Boundary; Portland, Oregon, 1921 September 2011 The lithosphere-asthenosphere boundary (LAB) marks a pronounced transition in the mechanical behavior of the upper mantle, separating the strong lithosphere from the weak asthenosphere beneath it. Although ...
It is mostly made up of iron(铁) and almost as hot as the inner core.The next part is the mantle(地幔). It cir-cles the outer core and is about 2, 900 kilome-ters thick, making it the earth's thickest part.The mantle is mostly made up of rock, but it also includes some ...
Question: What is the temperature at the bottom of the ocean? Ocean Temperatures: The ocean is made up of layers. The topmost area, which receives the most sunlight, has the warmest temperatures. Each layer below the surface becomes incrementally cooler the deeper you go. ...
He published his finding in a 1919 journal — the first person to introduce the idea that there is a sharp boundary made up of a different material that separates the superior crust from the mantle beneath it. It's now known as the Mohorovicic discontinuity. How Deep Is Mohorovicic Discontinu...
Magma is hot, molten material that comes from within Earth's mantle or crust and is forced out as lava during volcanic eruptions. It typically contains silicates, suspended crystals and dissolved gases [source: Oxford Dictionary of Science]. Another common categorization, called the Volcano Explos...

“But modeling the long-term evolution of ocean pH is a notoriously difficult problem, as it involves almost all of the components of the Earth system: the atmosphere, the ocean, the crust, and the mantle,” Guo said. How Atmospheric CO2Shapes Ocean Chemistry ...
