Document Summary
Atmospheric properties include temperature, pressure, and humidity atmospheric pressure: the force per unit area produced by a column of air, also decreases with altitude, b/c at higher altitudes fewer molecules are pulled down by gravity. Relative humidity: the ratio of water vapour a given amount of air contains to the maximum amount it could attain at a given temp. Microclimate: the side of a hill that is sheltered from wind or direct sunlight can have a www. notesolution. com totally dif weather pattern, from the side facing into the wind or sunlight.
