Abiotic Cycles

Cards demonstrating the steps of the Water, Carbon, and Nitrogen Cycles

Rain, ice, and snow fall from the sky. Water Cycle: Precipitation
Water runs along the surface of the ground, often finding its way to lakes and rivers. Water Cycle: Runoff
Water vapor cools down and forms liquid droplets of water. These water droplets form clouds. Water Cycle: Condensation
Liquid water heats up and forms water vapor that heads into the atmosphere. Water Cycle: Evaporation
During the process of cellular respiration, animals release water vapor. Water Cycle: Respiration
During the process of cellular respiration, plants release water vapor. Water Cycle: Transpiration
Water seeps into the ground to become ground water. Water Cycle: Percolation
Carbon is release into the atmosphere when burning these for energy. Carbon Cycle: Burning Fossil Fuels
Carbon is release into the air when burning these to make space for farms and more. Carbon Cycle: Burning Forests
Carbon is released into the atmosphere when these organisms break down dead organic matter. Carbon Cycle: Decomposers
Carbon is released into the air (and recaptured by plants) when animals go through this process. Carbon Cycle: Respiration
Carbon is consumed by plants when they use this process to make oxygen. Carbon Cycle: Photosynthesis
Nitrogen is released into the air by these organisms. Nitrogen Cycle: Nitrogen-Releasing Bacteria
Nitrogen is captured by these organisms, which often reside in plant roots. Nitrogen Cycle: Nitrogen-Fixing Bacteria
Nitrogen is returned from deceased organisms into the ground by these organisms. Nitrogen Cycle: Decomposers
Animals get nitrogen by doing this. Nitrogen Cycle: Eating organic matter like plants.
