In this model the Solar System formed from a large rotating cloud of interstellar dust and gas called the solar nebulaIt was composed of hydrogen and helium created shortly after the Big Bang 138 Ga billion years ago and heavier elements ejected by supernovae. Its monatomic form H is the most abundant chemical substance in the Universe constituting.
What Is The Correct Arrangement Of The Earth S Layers From The Least Dense To Most Dense Quora
The lowest part of the mantle next to the core-mantle boundary is known as the D D-double-prime layer.
. The mantle is divided into upper and lower mantle separated by a transition zone. Earths mantle extends to a depth of 2890 km making it the planets thickest layer. The pressure at the bottom of the mantle is 140 GPa 14 Matm.
The chemical symbol for Hydrogen is H. It is assumed that there is no heat transfer out of the bottom of the lowest layer. Hydrogen is a chemical element with atomic number 1 which means there are 1 protons and 1 electrons in the atomic structure.
The standard model for the formation of the Solar System including the Earth is the solar nebula hypothesis. Soil temperature is set at the middle of each layer and heat transfer is calculated at the interfaces between them. The surface is at 0 cm.
The mantle is composed of silicate rocks richer. Temperature of the soil in layer 1 0 - 7 cm of the ECMWF Integrated Forecasting System. With a standard atomic weight of circa 1008 hydrogen is the lightest element on the periodic table.
