The Composition and Structure of Earth | Physical Geography

The Composition and Structure of Earth. Core, mantle, and crust are divisions based on composition. The crust makes up less than 1 percent of Earth by mass, consisting of oceanic crust and continental crust is often more felsic rock. The mantle is hot and represents about 68 percent of Earth's mass. Finally, the core is mostly iron metal.

Bacterial cell structure - Wikipedia

The cell envelope is composed of the cell membrane and the cell wall.As in other organisms, the bacterial cell wall provides structural integrity to the cell. In prokaryotes, the primary function of the cell wall is to protect the cell from internal turgor pressure caused by the much higher concentrations of proteins, and other molecules inside the cell compared to its external environment.

The Sun. The sun is a yellow dwarf star. It is a star because it produces light and energy by means of nuclear fusion converting hydrogen to helium. It is the heat and light generated from the sun that makes life on Earth possible. The sun lies in the centre of the solar system and contains more than 99% of the solar system's mass.

Internal Structure of Neptune | Sciencing

Dark belts of unknown composition and large white methane clouds are present in the upper atmosphere. Wind speeds on Neptune can reach 2,100 kilometers per hour (1,312 miles per hour) and produce storm systems. The storms may be driven by an internal heat source as Neptune radiates 2.6 times the energy it absorbs from the sun.

Atmospheric particles with long atmospheric lifetimes affect Earth's radiative balance. These particles typically consist of multiple chemical species. The tendency for these particles to scatter and/or absorb radiation depends on their internal structure and composition as well as their overall size and shape. In this work, selected urban ambient air particles were investigated using ...

Jupiter - Jupiter - The interior: The atmosphere of Jupiter constitutes only a very small fraction of the planet, much as the skin of an apple compares with its contents. Because nothing can be directly observed below this thin outer layer, indirect conclusions are drawn from the evidence in order to determine the composition of the interior of Jupiter.

Research highlights Drumlin formation is a centuries-old problem yet to be fully resolved. A comprehensive synthesis of drumlin composition and internal structure is presented. Despite complexity, we propose five basic types of drumlin for theories to target. Drumlin composition is often related to pre-existing sediments. As such, all but purely bedrock forms can be accommodated by a …

Geology of the Moon - Wikipedia

The geology of the Moon (sometimes called selenology, although the latter term can refer more generally to "lunar science") is quite different from that of Earth.The Moon lacks a true atmosphere, which eliminates erosion due to weather; it does not have any known form of plate tectonics, it has a lower gravity, and because of its small size, it cooled more rapidly.
