Core Content
  • SC-05-2.3.1
  • Students will:
      • キdescribe the circulation of water (evaporation and condensation) from the surface of the Earth, through the crust, oceans, and atmosphere (water cycle);
      • キexplain how matter is conserved in this cycle.
  • Water, which covers the majority of the Earth’s surface, circulates through the crust, oceans, and atmosphere in what is known as the water cycle.

slide5

What is the water cycle?

The continuous movement of water between Earth’s surface and the air is the water cycle.

condensation

precipitation

watershed

evaporation

transpiration

runoff

All water on Earth is recycled constantly.

groundwater

slide6

What is the carbon cycle?

combustion (human-made and natural)

CO2 in air

photosynthesis

dissolved

CO2 in water

respiration

decomposition

marine plankton remains

coal

natural gas

oil

rock

The carbon cycle is the continuous exchange

of carbon among living things.

slide7

What is the nitrogen cycle?

nitrogen gas in air (N2)

The nitrogen cycle is the continuous trapping of nitrogen gas into compounds in the soil and its return to the air.

nitrogen fixation

denitrification

absorption

decomposition

nitrate

ammonia

nitrite

slide8

What roles do plants play in the water, carbon, and nitrogen cycles?

Water cycle: Plants release water to the atmosphere through transpiration.

Carbon cycle: Plants turn carbon dioxide into carbon-rich foods.

Nitrogen cycle: Plants play a key role in housing bacteria that fix nitrogen and transform it into a usable form that other plants can build with.
