Geosphere may be taken as the collective name for the lithosphere, hydrosphere, cryosphere, atmosphere and biosphere.
In Aristotelian physics, the term was applied to four spherical natural places, concentrically nested around the center of the Earth, as described in the lectures Physica and Meteorologica. They were believed to explain the motions of the four terrestrial elements: Earth, Water, Air and Fire.
In modern texts and in Earth system science, geosphere refers to the solid parts of the Earth; it is used along with atmosphere, cryosphere, hydrosphere, and biosphere to describe the systems of the Earth (the interaction of these systems with the magnetosphere is sometimes listed). In that context, the term lithosphere is used instead of geosphere or solid Earth. The lithosphere only refers to the uppermost layers of the solid Earth (oceanic and continental crustal rocks and uppermost mantle). — Wikipedia
Earth science or geoscience is a widely embraced term for the fields of natural science related to the planet Earth. It is the branch of science dealing with the physical constitution of the earth and its atmosphere. Earth science is the study of our planet’s physical characteristics, from earthquakes to raindrops, and floods to fossils. Earth science can be considered to be a branch of planetary science, but with a much older history.
There are both reductionist and holistic approaches to Earth sciences. It is also the study of the Earth and its neighbors in space. Some Earth scientists use their knowledge of the Earth to locate and develop energy and mineral resources. Others study the impact of human activity on Earth’s environment, and design methods to protect the planet. Some use their knowledge about Earth processes such as volcanoes, earthquakes, and hurricanes to plan communities that will not expose people to these dangerous events.
The Earth sciences can include the study of geology, the lithosphere, and the large-scale structure of the Earth’s interior, as well as the atmosphere, hydrosphere, cryosphere and biosphere. Typically, Earth scientists use tools from geography, chronology, physics, chemistry, biology, and mathematics to build a quantitative understanding of how the Earth works and evolves. — Wikipedia
Earth system science (ESS) is the application of systems science to the Earth sciences. In particular, it considers interactions between the Earth’s “spheres”—atmosphere, hydrosphere, cryosphere, geosphere, pedosphere, biosphere, and, even, the magnetosphere —as well as the impact of human societies on these components. At its broadest scale, Earth system science brings together researchers across both the natural and social sciences, from fields including ecology, economics, geology, glaciology, meteorology, oceanography, paleontology, sociology, and space science. Like the broader subject of systems science, Earth system science assumes a holistic view of the dynamic interaction between the Earth’s spheres and their many constituent subsystems, the resulting organization and time evolution of these systems, and their stability or instability. Subsets of Earth system science include systems geology and systems ecology, and many aspects of Earth system science are fundamental to the subjects of physical geography and climate science. — Wikipedia

Mineral Resource of the Month: Phosphate
by U.S. Geological Survey on October 23, 2018 at 10:00 am
Phosphate rock refers to unprocessed ore and beneficiated concentrates that contain some form of apatite, a group of calcium phosphate minerals. Apatite in phosphate rock is the primary source for phosphorus in phosphate fertilizers. More than 80 percent of the world’s current production of phosphate rock is mined from sedimentary deposits, which were formed by the deposition of phosphate-rich materials in marine regions. Most of the rest comes from igneous deposits of carbonatites and […]
Monsoon strength affects global ice volumes, not...
by Adityarup "Rup" Chakravorty on October 22, 2018 at 10:00 am
In the 1920s, Serbian scientist Milutin Milankovitch proposed that cyclical changes in Earth’s orbital eccentricity, as well as its axial tilt and orientation, shape global climate. Part of his theory — widely accepted since — is that the amount of solar radiation, or insolation, reaching high northern latitudes is a major factor in regulating global ice volume and albedo, which in turn control the strength of tropical monsoons. But in a new study, researchers suggest […]

Despite growing up in Iceland, with Earth’s most volcanically active landscape as his playground, Thorvaldur Thordarson had no idea he would grow up to be a volcanologist. Nor did he suspect that his career path would take him all over the world to witness eruptions and aftermaths on six continents. […]
First Antarctic tetrapods
by Lucas Joel on October 18, 2018 at 10:00 am
Tetrapods include all those animals with four limbs. Humans are tetrapods, as are dogs and dinosaurs and salamanders. The earliest tetrapods evolved on land from fish with bony fins during the Devonian Period between about 420 million and 359 million years ago. Until now, fossils of the earliest four-legged forms were only known from equatorial regions, but paleontologists working in South Africa now report the discovery of fossil tetrapods that lived in the Late Devonian Antarctic.

Sipping carbon-neutral fuel from the atmosphere
by Mary Caperton Morton on October 16, 2018 at 10:00 am
In the near future, vehicles may be powered by carbon that comes from the sky, rather than out of the ground. Direct Air Capture (DAC) technology pulls carbon dioxide out of the atmosphere and converts the carbon into pellets that can be used to make hydrocarbon fuel that works in traditional engines. A new study details the process, which has been tested over the last three years, and offers some cost-saving solutions that make DAC more economically feasible than ever. […]

on June 4, 2018 at 7:46 pm
Researchers at Washington State University and the University of Idaho have found a new way to estimate how fast magma is recharging beneath the Yellowstone supervolcano. While their findings offer no help in predicting if the volcano will erupt, they can now get a better understanding of a key factor—a pool of basalt magma recharging the system—in how it works. […]

on February 5, 2018 at 6:00 pm
Childhood play experiences strongly shape a person's spatial skills, according to a new CIRES-led study—those skills can be critical to success in fields like science and engineering. Young adults who played with construction-based toys such as Legos, or with certain types of video games outperformed other peers in tests of spatial reasoning—like the skill needed to mentally rotate objects. And most notably, the new research found that gender differences in spatial skills disappear […]
2011 Tohoku-oki earthquake: Results from seismic...
on September 5, 2017 at 5:12 pm
A striking finding of the 2011 Tohoku-oki earthquake (Mw 9.0) is that more than 50 meters of coseismic fault slip reached the trench axis. In addition to this, seismological studies found a clear depth-dependent variation in the source location between high- and low-frequency seismic energy radiation. However, structural features that may control the slip behavior in the rupture zone have not been well examined. […]
