What is the main reason for acid mine drainage? Acid mine drainage (AMD) is the runoff produced when water comes in contact with exposed rocks containing sulfur-bearing minerals that react with water and air to form sulfuric acid and dissolved iron. This acidic run-off dissolves heavy metals including copper, lead, and mercury which pollute ground […]

Are all atoms the same in an element? Yes, all things are made of atoms, and all atoms are made of the same three basic particles – protons, neutrons, and electrons. But, all atoms are not the same. You know that the number of protons in an atom determines what element you have. What property […]

What is effective overburden pressure? When the soil is subjected to some load, it transfers the load to water in the pores and soil grains. This is defined as effective overburden pressure and otherwise will be called as inter-granular stress or effective stress. It increases with increasing depth of soil. What is Geostatic pressure? 1. […]

How many alternate universes are there? One obvious question that arises, then, is exactly how many of these parallel universes might there be. In a new study, Stanford physicists Andrei Linde and Vitaly Vanchurin have calculated the number of all possible universes, coming up with an answer of 10^10^16. How many universes are there in […]

What does a changing magnetic field causes? A changing magnetic field induces a current in a conductor. For example, if we move a bar magnet near a conductor loop, a current gets induced in it. The E.M.F. E induced in a conducting loop is equal to the rate at which flux ϕ through the loop […]

Why did NASA stop using space shuttles? In 2004, President Bush gave a speech that outlined the end of the shuttle era, without clearly identifying what would come next (or how much it would cost). This decision left NASA in limbo, as they were suddenly dependent on the Russians for access to space. Is the […]

What can cause a population to be in a uniform distribution? Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality. Clumped patterns usually occur when resources are concentrated in small areas within a larger habitat or because of individuals forming social groups. What are the factors for population […]
