What is the most important gas in the atmosphere ?
Nitrogen & Oxygen
Explain each matter
condensation-when gas or vapor turns into a liquidevaporation-from a liquid to a vaporsublimation-change directly from the solid to the gaseous state without becoming liquid.freezing-to change from a liquid directly to a solid
what is relative humidity ?
The amount of water vapor present in air expressed as a percentage of the amount needed for saturation at the same temperature.
what is a dew point ?
The atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form.
explain the difference
orographic lifting- occurs when an air mass is forced from a low elevation to a higher elevationfrontal wedging-The forced lifting of warm, less dense air over colder air in the vicinity of a frontlocalized convective lifting-Unequal surface heating that causes localized pockets of air (thermals) to rise because of their buoyancy..
what is a front ?
The boundary between two air masses that have different temperatures or humidity
what makes air stable ?
air that does not possess a tendency to rise. It is denser than the air above it,
