Apr 15, 2014 · The Cretaceous , derived from the Latin “creta” (chalk), usually abbreviated K for its German translation Kreide (chalk), is a geologic period and system from circa 145 ± 4 to 66 million years (Ma) ago. In the geologic timescale, the Cretaceous follows the Jurassic period and is followed by the Paleogene period of the Cenozoic era.

Earth system science focuses on the interrelationships among different components of the Earth system.The mid-Cretaceous climate was warm at high latitudes. The gentle temperature gradients resulted in weaker winds blowing over the oceans, and upwelling of ocean waters was weaker. The absence of strong wind-driven circulation and warmer ocean waters contributed to the general stagnation of the lower portion of the mid- Cretaceous ocean. The Cretaceous System is divided into two rock series, Lower and Upper, which correspond to units of time known as the Early Cretaceous Epoch (145 million to 100.5 million years ago) and the Late Cretaceous Epoch (100.5 million to 66 million years ago).Numerical solutions for the Solar System’s orbital motion provide Earth’s orbital parameters in the past, which are widely used to date geologic records and investigate Earth’s paleoclimate (1–11).The Solar …26-Jul-2022 ...
