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.
Orographic rainfall is when a parcel of air containing water vapor  gets to a mountain, it is then forced upwards (the mountain  blocking its way).    As the parcel o â¦ f air is forced upwards, it expands (adiabatic  expansion) and also cools.aking the world better, one answer at a time. Orographic effect occurs when an air mass approaches a mountain range and is rapidly forced upward, causing any moisture to cool and create precipitation in the form of rain or snow. Quick answer: Rapidly rising air forced up by mountains creates rain or snow.
