Since 1940, the amount of fresh water used by humanity has roughly quadrupled as world population has doubled. Some water experts estimate the practical upper limit of usable renewable fresh water lies between 9,000 and 14,000 cubic kilometers yearly. That suggests a second quadrupling of world water use is unlikely.
First Quarter Moon and The Moon Phases. First Quarter Moon. The first quarter moon (often called a âhalf moonâ), happens when the moon is at a 90 degree angle with respect to the Earth and Sun. So we are seeing exactly half of the moon illuminated and half in shadow. Each lunar cycle begins with a new moon.
In direct opposition to the new moon, the full moon, the phase of the moon where the moon is entirely visible, will set during sunrise and rise during sunset. The first quarter moon will rise one fourth of a day, that is to say six hours, after the sun, so at noon. It will set a quarter of a day, again six hours, after the sun, so around midnight. The third quarter moon is the opposite of that.
