Few people today know that the Milky Way is a spiral arm of our galaxy, which contains such a dense cluster of stars that in the

past it appeared not as individual points of light but as a splash of light across the night sky. Why is it no longer visible this way?

Ciclo Hidrológico

El ciclo del agua no se inicia en un lugar específico, pero para esta explicación se asumirá

que comienza en los océanos. El Sol, que dirige el ciclo del agua, calienta el agua de los océanos,

la cual se evapora hacia el aire como vapor de agua. Corrientes ascendentes de aire llevan el

vapor a las capas superiores de la atmósfera, donde una temperatura más baja causa que el vapor

de agua se condense y forme las nubes. Las corrientes de aire, mueven las nubes sobre el globo,

las partículas de nube colisionan, crecen y caen en forma de precipitación. Parte de esta

precipitación cae en forma de nieve, y se acumula en capas de hielo y en los glaciares, los cuales

pueden almacenar agua congelada por millones de años. En los climas más cálidos, la nieve

acumulada se funde y se derrite cuando llega la primavera. La nieve derretida corre sobre la

superficie del terreno como agua de deshielo y a veces provoca inundaciones. La mayor parte de

la precipitación cae en los océanos o sobre la tierra, donde, debido a la gravedad, corre sobre la

superficie como escorrentía superficial.

Una parte de esta escorrentía alcanza los ríos en las depresiones del terreno, en la

corriente de los ríos el agua se transporta de vuelta a los océanos. El agua de escorrentía y el

agua subterránea que brota hacia la superficie, se acumula y almacena en los lagos de agua

dulce. No toda el agua de lluvia fluye hacia los ríos, una gran parte es absorbida por el suelo

como infiltración. Parte de esta agua permanece en las capas superiores del suelo, y vuelve a los

cuerpos de agua y a los océanos como descarga de agua subterránea. Otra parte del agua

subterránea encuentra aperturas en la superficie terrestre y emerge como manantiales de agua

dulce. El agua subterránea que se encuentra a poca profundidad, es tomada por las raíces de las

plantas y transpirada a través de la superficie de las hojas, regresando a la atmósfera. Otra parte

del agua infiltrada alcanza las capas más profundas de suelo y recarga los acuíferos, los cuales

almacenan grandes cantidades de agua dulce por largos períodos de tiempo. A lo largo del

tiempo, esta agua continúa moviéndose, parte de ella retornará a los océanos, donde el ciclo del

agua comienza nuevamente
