Major Geological Events Seem to Follow a Rhythmic Pattern of 27.5 Million Years, Researchers Call It Earth’s ‘Pulse' Dozens of major geological events over the past 260 million years, from sea level ...
Scientists have discovered an anomaly related to the increase in the level of beryllium-10 in ocean sediments at the bottom ...
The eruption was one of the largest of the 19th century, but the identity of the volcano responsible has long been unclear.
Sedimentation is controlled by them, and the stratigraphic series constitutes a record, written on tablets of stone, of these lesser and greater waves which have pulsed through geologic time.” ...
The beginning and end of each chunk of time in the geologic time scale is determined by when some species appeared or disappeared from the fossil record. When many species went extinct around the same ...
Understanding Earth's Deep Past provides an assessment of both the demonstrated and underdeveloped potential of the deep-time geologic record to inform us about the dynamics of the global climate ...
Sometime this century they may become acidified to the point that corals can no longer construct reefs, which would register in the geologic record as a “reef gap.” Reef gaps have marked each ...
Ripples are one of the clearest indicators of an ancient standing body of water that can be provided by the geologic record. The team estimates that the ripples formed around 3.7 billion years ago ...
For example, analyzing the geologic history can uncover a more detailed record of past earthquakes preserved in the rocks. This knowledge allows scientists to make more informed assessments about ...
In the field of paleoclimatology, our overarching objective is to use the geologic record to understand how Earth’s climate system operates. Paleoceanography may focus on the role of the oceans in ...
