Total questions: 32
Worksheet time: 8hrs 47mins
All of the carbon in existence is continually recycled in the carbon cycle.
How is the carbon cycle similar to the water cycle?
Both involve liquid substances falling to the Earth from the atmosphere?
Neither process works at low temperature.
Both involve the transfer of substances between animals, plants, and the Earth.
Both involve the transfer of substances between the earth and outer space.
All of these

Which of the following processes does NOT move carbon to the atmosphere?
Animal respiration (Breathing)
Volcanic eruption
Photosynthesis
Burning fossil fuels
Organisms that do not decompose can be buried and become what part of the lithosphere?
water
nutrients
air
fossil fuels
What is a way that carbon can move?
From hydrosphere to the biosphere through drinking water
From lithosphere to hydrosphere through weathering and erosion
From the atmosphere to lithosphere through diffusion
From the atmosphere to the biosphere through respiration (breathing)
Which one of these does not add CO2 to the atmosphere?
How do plants affect the air that animals and people breathe?
Plants use oxygen from the air to make their own food
Plants release pollution into the air
Plants take in carbon dioxide and release oxygen
Plants take in oxygen and release carbon dioxide
Why is burning fossil fuels harmful?
they cause cancer
They can get extremely hot
it increases the amount of carbon dioxide in the atmosphere
this would destroy fossils
Which of the following add carbon dioxide to the atmosphere?
volcanoes
combustion of fossil fuels
animal and plant respiration
all of these
Which of the following is correct?
There is as much carbon on earth as when it was formed
Carbon is being created whenever it is recycled
Carbon is lost every time it is recycled
Carbon changes to different forms and is never recovered
What is happening at 1?
respiration: releasing CO2
decomposing CO2 in the soil
photosynthesis: absorbing CO2
turning CO2 from the atmosphere into organic molecules

What do 'plants' do with the carbon they receive?
They turn it into water
They don't need carbon
They turn it into food by photosynthesis
They keep it forever
