Why do clouds often form above mountain peaks?

Which atmospheric measurement is a measure of moisture or water vapor in the air relative to the total the air can hold in grams of water vapor per kilogram of air (g/m3) and uses a hygrometer or psychrometer to take measurements? Group of answer choices Air Pressure Humidity Temperature Wind Direction   Which type of cloud tends to be fluffy with a vertical appearance? Group of answer choices Cumulus Stratus None of these Cirrus   Which term describes the circular movement of heat in fluids, including water and air, with warm molecules rising and cooler molecules falling? Group of answer choices Radiation Conduction None of these Convection

Freezing rain occurs with the following variation of temperature with height: - a shallow below-freezing layer near the surface, with an above-freezing layer over it, and a deep below-freezing layer aloft - a shallow above-freezing layer near the surface, with below-freezing layer over it, and a deep above-freezing layer aloft - a below-freezing layer through depth above - a deep below-freezing layer near the surface, with an above-freezing layer over it, and a deep below-freezing layer aloft

At what temperature does water vapor condense at the pressure of an atmosphere?
