Study Notes
Atmospheric Composition
- Nitrogen (N2) is the most abundant gas in the Earth's atmosphere.
Rock Formation
- Sedimentary rocks are formed through the process of lithification, which involves the compression and cementation of sediments.
Plant Photosynthesis
- Chlorophyll, a green pigment, plays a crucial role in plant photosynthesis, as it absorbs light energy and facilitates the conversion of CO2 and H2O into glucose and O2.
