This flows downslope as it "collapses to the base of the exposure". [12] The floor or base of the retrogressive thaw slump is covered in then sediment—mudflows and braided hills. [9] As the headscarp progressively retreats, the slump floor extends. [9] As the slopes thaw, the ice-rich permafrost is exposed and turns into a mud slurry. [12]
Earth science or geoscience includes all fields of natural science related to the planet Earth. [1] This is a branch of science dealing with the physical, chemical, and biological complex constitutions and synergistic linkages of Earth's four spheres: the biosphere , hydrosphere / cryosphere , atmosphere , and geosphere (or lithosphere ).
Aphanitic (a = not, phaner = visible) rocks, in contrast to phaneritic rocks, typically form from lava which crystallize rapidly on or near Earth's surface. When extrusive rocks make contact with the atmosphere they cool quickly, so the minerals do not have time to form large crystals. The individual crystals in an aphanitic igneous rock are ...
Science portal; Earth science (also known as geoscience, the geosciences, or the Earth sciences) includes all the sciences related to the planet Earth. It is arguably a special case in planetary science, Earth being the only known life-bearing planet known to Homo sapiens. There are both reductionist and holistic approaches to Earth science.
Heavy Moisture led to land slides of blocks of overhanging earth. Thus the slumps retained their original layering sequence. A slump is a form of mass wasting that occurs when a coherent mass of loosely consolidated materials or a rock layer moves a short distance down a slope. [1]
The Science Education Resource Center, Carleton College, offers the following description: "Earth System science embraces chemistry, physics, biology, mathematics and applied sciences in transcending disciplinary boundaries to treat the Earth as an integrated system. It seeks a deeper understanding of the physical, chemical, biological and ...
