Study Notes
Carbon Cycle
- Respiration and combustion return carbon dioxide to the atmosphere.
- Photosynthesis removes carbon dioxide from the atmosphere.
- Decomposers decay animals and release carbon dioxide.
- Denitrification is the process of converting nitrates and nitrites into nitrogen gas.
Water Cycle
- Evaporation, condensation, and precipitation are three main processes in the water cycle.
Earth's Structure
- The rigid outer layer of Earth is called the lithosphere.
Biosphere and Atmosphere Interaction
- Plants and animals use oxygen and carbon dioxide during respiration and photosynthesis.
Minerals and Rocks
- Chemical composition and crystalline structure distinguish minerals from other minerals.
- Rocks are made of one or more minerals.
K-Pg Mass Extinction
- High levels of iridium in rock and the Chicxulub crater support the theory that an asteroid caused the K-Pg mass extinction event.
