Is a sinkhole a natural hazard? Sinkholes can form on both land masses and ocean ground surfaces. They can have both, natural and anthropogenic (human made) causes. Most natural sink holes are often caused by erosion which can either be physical or chemical. Human made sink holes are often a result of underground development such […]

Why does the pressure exerted by gas not depend on the type of gas? Explanation: the pressure exerted by a gas does not depend on the type of the gas because pressure is a physical force its has not chemical composition. So, pressure depends upon the numbers of molecules of the gas because gas molecules […]
