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

by David Moscato on February 17, 2019 at 11:00 am
In 1972, the first dinosaur remains ever found in Arkansas — a fossilized foot — were pulled out of a gravel and sand pit near the Sevier County town of Lockesburg in the southwestern part of the state. Though the foot remained a scientific mystery for decades, it became something of a local celebrity. […]
Humans accidentally created new rivers in Europe
by Lucas Joel on February 15, 2019 at 11:00 am
Meandering rivers that flow through and transport sediment to deltas often split off from their main courses and flow in different directions. This process, called avulsion, happens naturally when a river overflows its banks and the floodwaters carve out a new course for the river to follow. But humans can also trigger avulsions by changing the shape of the landscape, and in a new study, scientists report that people have been doing this for a very long time. […]
Free swimmers came back first after Great Dying
by Mary Caperton Morton on February 14, 2019 at 11:00 am
About 252 million years ago, at the boundary between the Permian and Triassic periods, the vast majority of marine and terrestrial life died out in the most devastating extinction event in Earth’s history. Earth’s ecosystems eventually recovered, but not in the way — or as quickly as — scientists thought. In a new study looking at how marine species reemerged in the Triassic, researchers report a surprising trend of recovery from the top of the food chain down. […]

on June 4, 2018 at 8:46 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 7:00 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 […]

on September 5, 2017 at 6:12 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. […]
