In earth science, we often divide different types of mechanical weathering into two major categories: **fracturing**, which includes frost- & salt-wedging, and **abrasion**, including sandblasting and sea salt weathering.Frost Wedging or Freeze-Thaw Frost Wedging/Ice Wedging or F...
Human-Related Biological Weathering Human beings have a dramatic weathering effect. Even a simple path in the woods has an impact on the soil and rocks that make up the path. Major changes affected by humans include: Construction -- moving, scoring, and smashing rock for construction of buildin...
aEarth system science representation of the biosphere at the intersection of the different components of the Earth system scaled to their respective volumes, providing an approximate global composition (in vol. %) of the compartments interacting at the surface of the Earth as well as the color cod...
Similarly, the distribution of U activity ratios within the profile leads to a definition of the a priori range of the U activity ratios in the mobility fluids. With these different constrains, the age of the beginning of U mobilisation and the values of mobilisation parameters can be quite ...
A simple model attempts only a rudimentary explanation of the real world. The hydrology model in this paper attempts to be the most elementary possible model of the week-to-week flow of a northern New England hardwood forest stream. The goal of the present model is to approximate the “...
