Document Summary
The atmosphere it is composed of nitrogen (78%) and oxygen (21%) the remaining 1% consists of water vapour, carbon dioxide, and other trace" gases. Water vapour in the atmosphere can result in cloud development and the formation of precipitation. Water vapour comes from evaporation from the oceans. Structure of the atmosphere all weather (ie. clouds and precipitation) is confined to the troposphere lowest 11 km of the atmosphere is where most weather is confined. Weather cannot rise up into the stratosphere as we go up, temperature goes down but in a specific layer, temperature warms as we go up. Clouds cloud names generally contain a prefix and suffix the prefix describes the height of the cloud; the suffix describes its appearance prefix: high cloud: cirro- 1: mid-level cloud: alto, low cloud: strato- suffixes, puffy: -cumulus, flat: -stratus ex: a high puffy cloud is called a cirrocumulus cloud.
