earth and space

• what is matter 


  anything that takes up space and can be weighed
• what is the photosynthesis equation

  carbon doixide+water-oxygen+glucose
• respiration equation


  oxygen+glucose-carbon dioxide+water+energy
• what is a carbon sink


  any feature of the environment that obsorbes carbon,keeping it from the atmosphere
• geological vs biological 


  geological is a long term cycle that occurs over millions of years and biological is a short term cycle that occurs over days,weeks,months and years.
• what is the greenhouse effect

  the process through heat is trapped near the earths surface by the greenhouse gas

  
• natural greenhouse effect vs enhanced greenhouse effect examples

  nge=water vapour,keeps temps stable over long periods of time ege=caused by humans,more co2 from burning fossil fuels,causes global warming
• what is global warming

  an increase in the average global temps caused by an increase in greenhouse gases
• carbon cycle

• examples of lithospheres


  soil,rocks,metals,vallys
• examples of atmosphere


  clouds,air,co2
• examples of hydrospheres


  anything to do with water
• examples of biosphere 


  humans
• solar system 


  .

  
• how does the lithosphere,the atmosphere,the hydrosphere and the biosphere interact


  .

  
• what are celestial bodies


  a natural object outside of the earths sphere
• what are different types of celestial bodies

  stars,planets,solar,systems,galaxies and black holes
• explain the big bang theory

  is a physical theory that describes how the universe expanded from a primordial state of high density and temperature.
