What models are available to estimate effect of surface water on groundwater quality?
Earth scienceAsked by: Willie Russell What is surface water modeling? Surface water models are used to simulate surface water conditions and to assess surface water availability. How do models contribute to water quality management? Modeling can be used to assess (predict) future water quality situations resulting from different management strategies. For example, assessing the improvement in
What is a typical value of the Péclet number for internal waves?
Earth scienceAsked by: Joshua Starboard What are internal waves in the ocean? Internal waves are the undersea equivalent of surface waves you see at the beach. They have a vital role in transferring heat, energy, and momentum in the ocean. The turbulence they create when they break helps move nutrient-laden water to the coastlines while moving
Why does the annual temperature range get bigger where latitude is higher?
Earth scienceAsked by: Joshua Starboard Why are there larger annual temperature changes at higher latitudes? At higher latitudes, the angle of solar radiation is smaller, causing energy to be spread over a larger area of the surface and cooler temperatures. How does latitude affect annual temperature range? There is a relationship between latitude and temperature around
How can I tell if a rock is really petrified wood?
Earth scienceAsked by: Brent Bakos Keep an eye out for little bits of sap or sap-like colors like red (often strong reds), orange, and tan around the smooth parts. Smooth sections are often 3 to 5 inches (7.6 to 12.7 cm) in length. If the specimen has no bark but looks and feels like wood, it’s
Possible Effects of a Nuclear Reactor Breach in the Mediterranean
Earth scienceAsked by: Brent Bakos What happens if Zaporizhzhia blows? According to experts, if shelling hit the nuclear waste stored at the Zaporizhzhia plant, it could cause a major leak. “If missile strikes hit the nuclear waste storage, then [nuclear] pollution could spread through air and water,” said Ozharovsky. What are the potential consequences of a
What are the environmental effects of leaking hydrogen from large-scale energy storage mechanisms?
Earth scienceAsked by: Melissa Robinson What are the environmental impacts of hydrogen energy? Using hydrogen energy isn’t hard on the environment, because only water and heat are released as byproducts. However, the process needed to produce hydrogen can be less environmentally friendly. To produce usable hydrogen, it has to be separated from water, biomass (plant and
How to locally identify a cold front passage?
Earth scienceAsked by: Melissa Robinson Look for a pressure minimum, a change in temperature trend and a shift in wind. A cold frontal will also generally bring drier air, and a warm front humid air, so this can also be used. How do you identify a cold front is occuring? An abrupt temperature change over a
How was Nastapoka arc formed?
Earth scienceAsked by: Zanarkand Sotero Most scientists, however, think the Nastapoka is an arcuate (bow-shaped) tectonic boundary, formed when one shelf of rock was pushed down under another one. If so, it would be the only one on Earth so round that it looks like it was made punched out a cookie cutter 280 miles across.
What generates the microseism?
Earth scienceAsked by: Zanarkand Sotero Microseism is the most continuous and ubiquitous seismic signal on Earth and is mostly generated by the ocean–solid earth interaction (Tanimoto et al., 2015). What causes microseism? In seismology, a microseism is defined as a faint earth tremor caused by natural phenomena. The term is most commonly used to refer to
Why don’t tropical cyclones hit Hawaii?
Earth scienceAsked by: Plain Phab Why do hurricanes not hit Hawaii? The pool of warmer water remains intact across the Pacific between 500 and 750 miles south of the Hawaiian Islands, and a hurricane which forms and moves due westward about 600 miles south of Hawaii can maintain its strength into the central Pacific. Does Hawaii
