Groundwater flow modeling has been a valuable tool in the assessment of this large environmental problem. However, due to the complexity of the hydrogeological setting, the modeling has been performed with various simple case models in lieu of a large complex model. Here we report the results ...
Groundwater flow regimes in the seasonally thawed soils in areas of continuous permafrost are relatively unknown despite their potential role in delivering water, carbon, and nutrients to streams. Using numerical groundwater flow models informed by observations from a headwater catchment in arctic Alaska...
Describing the water cycle would involve stating observations about rain, clouds, and water flow on the Earth's surface. 14 Explaining often requires a deeper understanding of a subject because it involves linking facts to theories, principles, or laws to clarify how something works or why ...
Across the stable density stratification of the abyssal ocean, deep dense water is slowly propelled upward by sustained, though irregular, turbulent mixing. The resulting mean upwelling determines large-scale oceanic circulation properties like heat and
Culture Media can be used for two different purposes: to support cell growth or promote differentiation and proliferation of cells during cellular development. Differentiation refers to the process where new tissues are created from stem cells by adding differentiating factors f...
Explain the differences between the structures of ice and snow. If cooling occurs at the bottom of the pond instead at the surface, would the pond freeze from the bottom up? Explain. Explain how groundwater weathers and erodes Earth materials. How did changing geologic conditi...
Describe the direction of heat flow and the kinetic energy of particles to explain what happens to ice in a glass of water over time. In order to go through a phase change, energy must be added or released from the syste...
them. True and quasi anti-repeaters can be robustly identified via a three-component single station or distributed network data. They are key indicators for stress perturbation transients or local stress heterogeneities. Since most of these observations were explained as the response to fluid migration...
Take a look at the donut chart below. In 1978 (inner ring), about 80 percent of home energy use went to heating homes (66 percent) and hot water (14 percent). Today, those figures have changed quite a bit and much less of our energy (62 percent) is now used this way (heating ...
Both animal and plant cells are surrounded by a membrane (plants then also have a cell wall around that). The cell membrane is semi-permeable. The cell depends on this feature to function so that select amounts of various solutes can flow in and out....
