Drought it difficult to define. why? select one: a. the term "drought is not recognized by the american meteorological society (ams), national oce and atmospheric administration (noaa) or the world meteorological organization as a scientific term for drought in one location will not necessarily apply to the next. c. many locations around the world do not collect data on precipitation amounts, which makes a global ght is region specific, which means that it is difficult to set a standard definition because the criteria dataset on precipitation statistics unavailable. therefore no formal definition exits d. drought research is a relatively new science and until there is enough statistically significant data to support a definition, none will exist
