higher the altitude, the lower the atmospheric pressure. Lower pressure
in turn causes water to evaporate more quickly, and water actually
boils at a lower temperature. The percentage of oxygen in the air at two
miles (3.2 km.) is the same as at sea level (21%). However, the air
pressure is 30% lower at the higher altitude due to the fact that the
atmosphere is less dense--that is, the air molecules are farther apart.
The important effect of this decrease in pressure is this: in a given
volume of air, there are fewer molecules present. This is really just
another way of saying that the pressure is lower. This is called Boyle's
law.</span>
I would venture to say that the country in South America that has the least amount of disposable water would be probably in northern Chile which is a desert ie the Atacama desert which stretches from the Pacific across to the Andes Mts while on the other hand, in southern Chile there is a temperate climate with significant rainfall and considerable disposable water.
Answer:
Los mares cerrados, como el Mar Mediterráneo, presentan mayores niveles de contaminación porque son entera o mayoritariamente formados por cuencas endorreicas, las cuales no tienen salida directa hacia el océano. De esta manera, las corrientes marítimas no desagotan sus residuos en el océano, sino que continúan retroalimentándose de manera cícilica, con lo que el conjunto de desechos que viaja en dichas corrientes se queda constantemente dentro de la misma cuenca.
Reason a is the correct one, as the european union has nothing to do with protection from invasions and Germany reunified many years ago.
