lithosphere : the outer part of the solid earth composed of rock essentially like that exposed at the surface, consisting of the crust and outermost layer of the mantle, and usually considered to be about 60 miles (100 kilometers) in thickness — Webster

Encyclopedia

Lithosphere is the rigid, outermost shell of a terrestrial-type planet, or natural satellite, that is defined by its rigid mechanical properties. On Earth, it is composed of the crust and the portion of the upper mantle that behaves elastically on time scales of thousands of years or greater. The outermost shell of a rocky planet, the crust, is defined on the basis of its chemistry and mineralogy. — Wikipedia

Introduction

Science

Geology is an science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time. Geology can also refer to the study of the solid features of any terrestrial planet or natural satellite such as Mars or the Moon. Modern geology significantly overlaps all other earth sciences, including hydrology and the atmospheric sciences, and so is treated as one major aspect of integrated earth system science and planetary science.

Geology describes the structure of the Earth beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth’s past climates. — Wikipedia

    Researchers have developed a new method for detecting small earthquake tremors and successfully applied it to the Nankai Trough, Japan. The technique allowed the accurate estimation of tremor location and propagation speed, leading to the first estimates of this fault's permeability -- crucial information in evaluation of earthquake rupture processes.

    Until now, researchers have found no evidence of global tectonic activity on planets outside our solar system. Scientists have now found that the material inside planet LHS 3844b flows from one hemisphere to the other and could be responsible for numerous volcanic eruptions on one side of the planet.

    Researchers have unearthed further details about radon concentration in the atmosphere before and after earthquakes, moving us closer to being able to anticipate when large earthquakes may hit.

  • How do you know where volcanic ash will end up?

    Until the eruption of Eyjafjallajökull volcano, models from the VAACs were based on the tracking of the clouds in the atmosphere. In the wake of this economic disaster for airlines, ash concentration levels have been introduced to make decisions on flight restrictions. However, a team discovered that even the smallest volcanic ash did not behave as expected. Its results will help to refine the way that volcanic ash is represented in forecasting models.

    Earthquakes in the Black Rock Desert are rare and capturing the seismic recordings from these earthquakes provides a glimpse into the volcanic system of the Black Rock Desert that, while not showing any signs of erupting, is still active.

    At some point between 300 million and 1 billion years ago, a large cosmic object smashed into the planet Venus, leaving a crater more than 170 miles in diameter. A team of Brown University researchers has used that ancient impact scar to explore the possibility that Venus once had Earth-like plate tectonics.

  • Geologic history written in garnet sand
    on January 14, 2021 at 9:21 pm

    On a beach on a remote island in eastern Papua New Guinea, a country located in the southwestern Pacific to the north of Australia, garnet sand reveals an important geologic discovery. Similar to messages in bottles that have traveled across the oceans, sediments derived from the erosion of rocks carry information from another time and place. In this case the grains of garnet sand reveal a story of traveling from the surface to deep into the Earth (~75 miles), and then returning to the surface […]

    As the largest orogenic plateau on Earth, the Qinghai-Tibet Plateau was caused by a complex crustal deformation process during the continuous collision and compression process between the Indian and Eurasian continents starting at least 60-50 Ma ago. The formation of the Qinghai-Tibet Plateau records the collision of the two continents and the deformation process and mechanism within the continents. Therefore, the Qinghai-Tibet Plateau is considered as a natural ideal laboratory for the study […]

    Phosphorus is an element essential for life. It is fundamental to all living organisms, and is a key component of RNA, DNA, and cell membranes. Phosphorus compounds must have been involved in the emergence of primordial life. Importantly though, these compounds were water soluble and reactive so that they could participate in various chemical processes. Only in this case could phosphorus be involved in phosphorylation, which enables the synthesis of complex molecules. However, phosphorus in […]
