Earth's different cycles

Multiple Select

Check the spheres/systems of Earth?

• Geosphere

• Hemisphere

• Hydrosphere

• Atmosphere

• Space

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?

• Evaporation

• Precipitation

• Condensation

• Transpiration

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

Oxygen cycle

• Closely works with the carbon cycle through photosynthesis and respiration

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
