between the earth's oceans, atmosphere, and land.
Water Cycle

4. z
Evaporation: the process of turning from liquid into vapor. Water
evaporates from lakes, oceans, ponds, and rivers creating
rain ​clouds in the sky.
Water Cycle
Condensation: the conversion of a vapor or gas to a liquid. When
the water begins to condense, water droplets (rain) are formed.
Precipitation: rain, snow, sleet, or hail that falls to the ground.
Precipitation is the process of the droplets falling back to the Earth.
Transpiration: is the process where plants absorb water through the
roots and then give off water vapor through pores in their leaves.
Percolation: where water travels downwards through the tiny
spaces between rocks and soil particles.

Carbon Cycle: The carbon cycle is driven by carbon production and
consumption.
Carbon Cycle

7. z
Carbon Production: Animals give off carbon dioxide when they
exhale. Carbon is also given off by factories, vehicles, and
decomposers.
Carbon Cycle
Carbon Consumption: Plants use carbon dioxide during
photosynthesis to make food and ​oxygen.
