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.
Not exact matches
The standard assumption has been that, while heat is transferred rapidly into a
relatively thin, well - mixed surface
layer of the ocean (averaging about 70 m in depth), the transfer into the deeper
waters is so slow that the atmospheric temperature reaches effective equilibrium with the mixed
layer in a decade or so.
As this sinking air mass weighs on the marine
layer, the latter compresses into a
thin layer with a
relatively high concentration
of water vapor.
