Carbon Moving in the Spheres of the Earth

Flow of Matter

Earth's biogeochemical cycles

Multiple Select

Check the spheres/systems of Earth

• Geosphere

• Hydrosphere

• Space

• Hemisphere

• Atmosphere

​Matter/Energy are moved from one sphere to another by cycles in Earth's spheres/systems.

• ​Water Cycle

• ​Oxygen Cycle

• ​Carbon Cycle

• ​Nitrogen Cycle

​The Water Cycle

• ​Water is moved by sun's energy

• different phases of water (gas, liquid, solid)

• Water is the only common substance found in all 3 phases of matter

Multiple Choice

What process changes water vapor into liquid water?

• E

• Condensation

• Precipitation

• Transpiration

​The Carbon Cycle

• ​Everything is made of carbon (an element)

• 4th most abundant element in the Universe. (comes from old stars)

• Carbon in the atmosphere keeps Earth warm/ too much causes the greenhouse effect

• Very slow cycle- takes carbon millions of years to go from soil to air

Multiple Select

Which ones give off carbon dioxide? (check all that apply)

• plants

• animals

• trees

• people

​The Oxygen Cycle

​

• Closely works with the carbon cycle through photosynthesis and respiration

​The Nitrogen Cycle

• needed for biological structures: cells, amino acids, and DNA

• needed for plants to produce chlorophyll which they use for photosynthesis

• 78% of our atmosphere is made up of Nitrogen
