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.
Explain the three main process involved in the water cycle First, water evaporates from lakes, streams, and oceans and risen into Earth's atmosphere. As water vapor rises, it cools and change back into a liquid. Second, when water vapor condenses, it forms clouds. Third, water droplets combine to form larger drops that fall to Earth as precipitation Put these atmospheric layer in the correct order 1- closest to the Earth's surface, 5 - farthest from the Earth's surface
