The continuous movement of condensation water between Earth’s surface and the air is precipitation watershed the water cycle. evaporation transpiration runoff groundwater All water on Earth is recycled constantly.• Evaporation: Changing of liquid into gas Lesson 1 a• Condensation: Changing of gas into liquid• Precipitation: Any form of water• Watershed: An area from which water is drained
  • 8. What is the Water Cycle What is the water cycle? The continuous movement of condensation water between Earth’s surface and the air is precipitation watershed the water cycle. evaporation transpiration runoff groundwater All water on Earth is recycled constantly.• Evaporation: Changing of liquid into gas Lesson 1 a• Condensation: Changing of gas into liquid• Precipitation: Any form of water• Watershed: An area from which water is drained• Runoff: water not absorbed into streams
  • 9. What is the carbon cycle
  • 10. What is the carbon cycle What is the carbon cycle? combustion CO2 in air (human-made and natural) photosynthesis dissolved respiration CO2 in water decomposition marine plankton coal natural gas remains oil rock The carbon cycle is the continuous exchange of carbon among living things. Lesson 1 b

What is the carbon cycle What is the carbon cycle? combustion CO2 in air (human-made and natural) photosynthesis dissolved respiration CO2 in water decomposition marine plankton coal natural gas remains oil rock The carbon cycle is the continuous exchange of carbon among living things. Lesson 1 b• Carbon is in every living thing• We take in carbon dioxide through the air
  • 13. What is the carbon cycle What is the carbon cycle? combustion CO2 in air (human-made and natural) photosynthesis dissolved respiration CO2 in water decomposition marine plankton coal natural gas remains oil rock The carbon cycle is the continuous exchange of carbon among living things. Lesson 1 b• Carbon is in every living thing• We take in carbon dioxide through the air• Animals give off through respiration
  • 14. What is the nitrogen cycle
  • 15. What is the nitrogen cycle What is the nitrogen cycle? nitrogen gas in air (N2) The nitrogen cycle nitrogen fixation is the continuous trapping of nitrogen gas into compounds in the soil and its return to the air. denitrification decomposition absorption nitrate ammonia nitrite Lesson 1 c
  • 16. What is the nitrogen cycle What is the nitrogen cycle? nitrogen gas in air (N2) The nitrogen cycle nitrogen fixation is the continuous trapping of nitrogen gas into compounds in the soil and its return to the air. denitrification decomposition absorption nitrate ammonia nitrite• Nitrogen is part of the genetic material in all cells Lesson 1 c
