What makes it rain Rain falls from clouds for the same reason anything falls to Earth. The Earth’s gravity pulls it. But every cloud is made of water droplets or ice crystals. Why doesn’t rain or snow fall constantly from all clouds The droplets or ice crystals in clouds are exceedingly small. The effect of gravity on them is minute. Air currents move and lift droplets so that the net downward displacement is zero, even though the droplets are in constant motion.
Droplets and ice crystals behave somewhat like dust in the air made visible in a shaft of sunlight. To the casual observer, dust seems to act in a totally random fashion, moving about chaotically without fixed direction. But in fact dust particles are much larger than water droplets and they finally fall. The average size of a cloud droplet is only 0. 0004 inch in diameter.

Passage 1
As Texas begins to recover from two weeks of devastating storms, a generally hidden truth about its economy will come to light again, Most of the builders and electricians who will have to repair the houses, remake the roads and re-establish the electrical power lines will have to take on undocumented workers in order to meet their contracts. In 1996 the Immigration and Naturalisation Service (INS) conservatively estimated that Texas had over 600000 undocumented immigrants doing the jobs no one else wants: hauling carcasses in packing plants, picking fruit, cleaning hotel rooms, or sorting out the unspeakable damage caused by natural disasters.
Mention the issue of these workers to a Texan, and he is liable to fall uncharacteristically silent. Even state legislators avoid the issue. They know that many of their constituents employ undocumented workers. They also know that the booming Texas economy is driven in part by the ready supply of cheap, di
