Document Summary

Earth is made up of 4 interacting spheres. Lithosphere: it includes all rocks and geological material, soil. Weather: condition of atmosphere at particular time and place, always changing. Air temperature: degree of hotness or coldness in the air. Humidity: amount of water vapour in the air. Recurring atmospheric circulation patterns associated to weather patterns. Front: boundary between air masses with different air temps and characteristics which interact producing precipitation and heating or cooling of air. El ninos: interactions of the atmosphere with the ocean across the tropical pacific. Global scale changes in rainfall, temperature induced by this. Temperature: measure of molecular energy within a substance. Thin gaseous composed mostly of nitrogen and oxygen and small traces of water vapour, carbon dioxide.
