New calculations of the composition of TRAPPIST - 1f, the fifth planet from the star, suggest a relatively thin layer of water (still far deeper than anything found on Earth) gives way to ice VI and ice VII, two different forms of ice that can form under high pressures.

The researchers developed a method for measuring strength and finding weak spots in the lithosphere, the outer layers of earth that include the crust and the outer mantle — the molten rock lurking just under the surface that can well up and create volcanoes.

The Montreal Protocol — one of the world's most successful environmental treaties — has protected the stratospheric ozone layer and avoided enhanced UV radiation reaching the earth's surface,» said UN Under - Secretary - General and UNEP Executive Director Achim Steiner.

On the hot young Earth, the outer layer was too weak and soft for plate tectonics to operate until the upper mantle cooled enough to allow sections of crust to slip under each other, or subduct, at collision zones some 3.2 to 2.5 billion years ago.

Rowley's team uncovered subtle mantle movements under eastern North America by including in their model a layer of relatively soupy rock, just beneath Earth's rigid outer shell, called the asthenosphere.

Understanding how layers of air insulate the surface of glaciers, for example, is vital to making accurate estimates of how fast they will melt — and sea levels will rise — as the Earth warms under its blanket of greenhouse gases.

But these cores formed under the weight of their planets» outer layers, under pressures of around 500 gigapascals — 5 million times atmospheric pressure on Earth — and typical temperatures of about 6,000 kelvin.

If you're like most people, you take soil — that thin layer of living earth under our feet — completely for granted.

1) Start by computing the total GHG - free air constant mass per unit area of a gas layer between any two heights under gravity g 2) Add in the hydrostatic equilibrium pressure change with height in the gravity field 3) Compute the total enthalpy per unit area of the layer realizing the layer possesses potential energy per unit area in earth's gravity field 4) From that, realize energy conservation imposes a constraint that total dry static energy is constant in the layer (within adiabatic control volume) 5) From this, realize and compute the total entropy (S) of the layer over the height of the layer 6) Transform S computation from height to pressure by way of hydrostatic eqn.
