The document discusses climate and its components. Climate is defined as the average weather over a long period of time, in contrast to weather which refers to short term conditions. A region's climate is determined by factors like altitude, latitude, and terrain. It is generated by interactions between the atmosphere, hydrosphere, cryosphere, land surface, and biosphere. The document also describes different types of rainfall including relief, frontal, and convection rainfall, and explains the water cycle of condensation, evaporation, and precipitation.
