To divide one power of ten by another, simply subtract the two exponents (see Multiplication/Division). Next, convert the two numbers from scientific notation to real numbers. Now add the two numbers normally. Finally convert to scientific notation if the coefficient is less than 1 or greater than 10.
Precipitation occurs when cloud droplets combine and grow large enough to fall to the earth the rate of evaporation as a drop falls to the earth also can affect its size. from: sadia aisa.
It is a part of the water cycle, and it is the loss of water vapor from parts of plants (similar to sweating) Weather Fronts - A weather front is a boundary separating two masses of air of different densities. Precipitation -any product of the condensation of atmospheric water vapor that falls under gravity. The main forms of precipitation include drizzle, rain, sleet, snow, and hail. Dew Point - The dew point is the temperature where water vapor condenses into liquid water. Condensation of water vapor starts when the temperature of air is lowered to its dew point and beyond.
