Not exact matches

The planetary architecture that provides Earth's sheltering field has been broadly understood for several decades now: a solid - iron inner core roughly the size of the moon, surrounded by a 1,400 - mile - thick outer core of liquid iron and nickel, with 1,800 miles of solid mantle above, topped by a crust of slowly drifting tectonic plates.

Besides having the right mix of ingredients and pressures, this range defines a well - known transition zone within the mantle, the 2900 - kilometer - or - so - thick layer of slowly circulating material that lies between Earth's crust and its outer core of molten iron.

«We're interested in what happens at the interface between tectonic plates — thick, solid parts that cover our planet — and material in the upper mantle beneath the plates,» Levin said.

Frozen mixtures of water, ammonia and methane make up a thick layer between the planets» atmosphere and core — known as the mantle.

Back then the Earth's lithosphere was already thick and cool, but the mantle was still very hot, providing enough energy to significantly weaken the lithosphere above the plumes.

The observed activity of 288P also reveals information about its past, notes Agarwal: «Surface ice can not survive in the asteroid belt for the age of the Solar System but can be protected for billions of years by a refractory dust mantle, only a few metres thick.»

Since the 1970s, prevailing opinion has held that Yellowstone's activity is driven by a giant plume of hot material rising up from the mantle, the thick middle layer of Earth's interior.

From early Earth history, the continental crust (Earth's thick solid outer skin that we live on) has accumulated mass from the underlying hot mantle.

We know that the planet has a partly solid, partly liquid core, composed largely of iron, surrounded by a thick, flowing mantle, topped by a thin layer of crust.

The model reveals the structure of the mantle — the thick shell of hot, compressed rock that lies between the crust and the core.

The mantle is the thick layer of hot rock between Earth's crust and core.

This hotter mantle would have made the crust beneath the oceans hotter and thicker than it is today, buoying it up relative to the continents, and the associated shallower ocean basins would have held less water, leading to the flooding of much of what is now land.

In a first, geologists have compiled a set of global observations of the movement of the Earth's mantle — the 3,000 - kilometer - thick layer of hot silicate rocks between the crust and the core.

And a «lot of water» here means hundreds or thousands of Earth oceans's worth of water, completely covering the silicate mantle of the planets, most likely in hundreds of km - thick high - pressure water ice layers, below thick liquid oceans or high - pressure steam atmospheres.

Unlike Earth, Mercury has only a relatively thin silicate mantle and crust, only 500 to 600 km (311 to 373 miles) thick.

Assuming an iron - rich planet with an internal structure like Earth, modelling results for the first discovered super-Earth (GJ 876 d) indicate the existence of a threshold in planetary diameter above which a super-Earth «most certainly» has a high water content (an «ocean planet» or «water world,» where thick layers of water and pressurized ice surround a rocky mantle and core); this threshold was found to be around 24,000 kilometers (or nearly 15,000 miles) in the particular case of GJ 876 d (Valencia et al, 2007).

The short and thick coat of the Great Dane can be blue, mantle harlequin, merle, black, brindle or fawn in color.

Temperature tends to respond so that, depending on optical properties, LW emission will tend to reduce the vertical differential heating by cooling warmer parts more than cooler parts (for the surface and atmosphere); also (not significant within the atmosphere and ocean in general, but significant at the interface betwen the surface and the air, and also significant (in part due to the small heat fluxes involved, viscosity in the crust and somewhat in the mantle (where there are thick boundary layers with superadiabatic lapse rates) and thermal conductivity of the core) in parts of the Earth's interior) temperature changes will cause conduction / diffusion of heat that partly balances the differential heating.

Conventional theory says that movement of the fluid mantle deep in the Earth slowly erodes this heavy root, allowing mountains to rise gradually... She argues that instead of eroding slowly away, the root heats up and oozes downward like a drop of thick syrup, abruptly breaking free and sinking into the hot mantle.
