B14c How materials are recycled? Flashcards
The diagram shows the water cycle.
Name and describe the process labelled 1
Evaporation
Water changes from a liquid into water vapour
The diagram shows the water cycle.
Name and describe the process labelled 3
Condensation
Water vapour changes into water droplets and forms clouds.
The diagram shows the water cycle.
Name and describe the process labelled 4
Precipitation
Rain/snow/hail/ falls from the clouds
The diagram shows the water cycle.
Name and describe the process labelled 6
Percolation
Water runs off the land and infiltrates the rocks
The diagram shows the water cycle.
Name and describe the process labelled 2
Transpiration
Water vapour leaves the leaf through the stomata and enters the atmosphere
The diagram shows the water cycle.
Name and describe the process labelled 5
Run off
Rain water flows into the rivers and streams to the sea
The diagram shows the carbon cycle.
Name the process labelled A
Photosynthesis
The diagram shows the carbon cycle.
Name the process labelled B
Respiration by plants
The diagram shows the carbon cycle.
Name the process labelled C
Decomposition or decay
The diagram shows the carbon cycle.
Name the process labelled D
Combustion
The diagram shows the carbon cycle.
Name processes A and B
A = Respiration
B = Photosynthesis
Describe how carbon dioxide is removed from the atmosphere
Used in photosynthesis
Diffuses into the leaf through the stomata
Carbon dioxide reacts with water to form glucose
Light provides the energy for the reaction
Describe the role of microorganisms in returning carbon to the atmosphere from dead plants and animals
Dead plants and animals decomposed
By microorganisms
Microorganisms respire the carbon compounds in the dead material
Releases carbon dioxide into the atmosphere
Describe the role of microorganisms in returning minerals from dead plants and animals to the soil
Dead plants and animals decomposed
By microorganisms
Microorganisms release the minerals from the dead material
Releases minerals into the soil
Minerals abslorbed by plants
