Answer:
When discussing drought, one must have an understanding of aridity and the difference between the two. Aridity is defined, in meteorology and climatology, as "the degree to which a climate lacks effective, life-promoting moisture" (Glossary of Meteorology, American Meteorological Society). Drought is "a period of abnormally dry weather sufficiently long enough to cause a serious hydrological imbalance". Aridity is measured by comparing long-term average water supply (precipitation) to long-term average water demand (evapotranspiration). If demand is greater than supply, on average, then the climate is arid. Drought refers to the moisture balance that happens on a month-to-month (or more frequent) basis. If the water supply is less than water demand for a given month, then that month is abnormally dry; if there is a serious hydrological impact, then a drought is occurring that month. Aridity is permanent, while drought is temporary.
The answer is no. The Caucasus Mountain does not separate European Russia from Asian Russia. It was the Ural Mountains that separates the European Russia from Asian Russia. Ural Mountains is a mountain range that stretches approximately from northwestern Kazakhstan through the western part of Russia.
The answer is density, temperature, and salinity. These are the factors that makes a current that is 50 meter less deep. The other choices will create a higher amplitude of the current.
126,720 feet.
Why?: For each inch on a map, it’s equal to 126,720 feet in reality. All maps are not drawn to scale, so we make them smaller and add a scale to ressemble what distances are necessary.
Hope this helps.
