New research led by the University of Cambridge has found rare evidence – preserved in the chemistry of ancient rocks from Greenland – which tells of a time when Earth was almost entirely molten.

Although past temperature variations in the tropics are of great importance to understanding the global climate system, little is known about their extent and chronological course. Researchers have now been able to demonstrate strong local cooling in the tropics during the last glacial period on the basis of glacier fluctuations and large stone stripes in … Glaciers and enigmatic stone stripes in the Ethiopian highlands

Geoscientists used 3D-printed rocks and an advanced, large-scale computer model of past earthquakes to understand and prevent earthquakes triggered by energy exploration.

Several years after scientists discovered what was considered the oldest crater a meteorite made on the planet, another team found it’s actually the result of normal geological processes. Title: The world’s oldest crater from a meteorite isn’t an impact crater after allSourced From: www.sciencedaily.com/releases/2021/03/210311094122.htmPublished Date: Thu, 11 Mar 2021 09:41:22 EST News…. browse around here … The world’s oldest crater from a meteorite isn’t an impact crater after all

Electrons arriving from the Sun are propelled by electrical energy generated as high as 30,000 kilometers above Earth, ultimately creating the dazzling displays of the northern and southern lights.

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. Title: Making sense of commotion … Making sense of commotion under the ocean to locate tremors near deep-sea faults

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

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. Title: Volcanoes might light up the … Volcanoes might light up the night sky of this 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.
