GEOHYDROLOGY HYDROLOGIC CYCLE The movement of water on the earth’s surface and through the atmosphere is known as the hydrologic cycle. Water is taken up by the atmosphere from the earth’s surface in vapour form through evaporation. It may then be moved from place to place by the wind until it is condensed back to its liquid phase to form clouds. Water then returns to the surface of the earth in the form of either liquid (rain) or solid (snow‚ sleet‚ etc.) precipitation. Water transport can also

This post is Part I of A Brief History of Disruptive Innovation. Part II can be found here. For thousands of years‚ beginning around 10‚000 BC in the Middle East‚ humankind embarked upon its first disruptive revolution. Until that point‚ humans had roamed the earth in hunter-gatherer societies‚ foraging for food. When ancient humans discovered farming‚ and began settling permanently‚ in one place‚ advancements in agricultural technology led to a surplus food supply‚ which in turn‚ led to surplus

Other limitations of the Airbus compared to Boeings in general is that the Airbus is based on hydraulic systems‚ the core of which are are pipes that carry hydraulic fluid under pressure. Any malfunction of this system can cause disasterous effects in terms of safety. Hydraulic fluid also has to be incompressible‚ meaning it is dense and heavy which contribute to the mass of the aircraft. As hydraulic fluids are petroleum based‚ they are flammable (https://www.quora.com/How-does-the-new-Airbus-A350XWB-compare-to-the-Boeing-787-Dreamliner)

permeability‚ k‚ is a product of Darcy’s Law. Darcy established an empirical relationship for the flow of water through porous media. This relationship has evolved into Darcy’s Law‚ which states: Q = A . k . i Where Q = flow rate (volume/time) i = hydraulic gradient (unitless) A = cross-sectional area of flow (area) k =

The fact that any human being would allow this to be done to other human beings all in the name of money is beyond me‚ but I’ll get into that later. What is hydraulic fracturing anyway? The U.S. contains gas fields that rival the oil fields sizes in Saudi Arabia. Ironically‚ it’s because of fracking that the United States now has enough oil and gas to potentially meet what has been an insatiable need for energy
