Sugar is your brain's preferred fuel source -- not table sugar, but glucose, which your body processes from the sugars and carbs you eat. That's why a glass of OJ or another fruit juice can offer a short-term boost to memory, thinking, and mental ability.
Best Answer: Technically each cardinal phase (First Quarter, Full, Last Quarter and New) are all momentary events. They occur at specific times and then pass immediately. A better way to ask the question is to ask how much time passes BETWEEN each phase. The answer to that question is 29.5 / 4 days. 29.5 days is the number of days that it takes for the moon to cycle through it's phases (called the synodic month)... The interstitial phases (Waxing Cresent, Waxing Gibbous, Waning Gibbous, and Waning Cresent) also last 29.5 / 4 days each...
As the Sun sets, the Moon rises with the side that faces Earth fully exposed to sunlight (5).The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days catching up because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth. At the new Moon phase, the Moon is so close to the Sun in the sky that none of the side facing Earth is illuminated (position 1 in illustration). In other words, the Moon is between Earth and Sun. At first quarter, the half-lit Moon is highest in the sky at sunset, then sets about six hours later (3).
