Study Notes
Environments
- Biophysical environments refer to the interactions between living (bio) and non-living (physical) components that form distinct environments on Earth.
- Understanding these interactions is crucial for conservation and coexistence with environments.
The Four Spheres
- The four spheres are: Atmosphere, Lithosphere, Hydrosphere, and Biosphere.
- Atmosphere: gases and particles surrounding Earth, including climate and weather variations.
- Lithosphere: Earth's solid outer shell, including earth and rock.
- Hydrosphere: all water on Earth and the system of water movements through the other spheres.
- Biosphere: all organic life, including plants and animals.
Interactions between the Spheres
- Each sphere plays a vital role in sustaining life on Earth.
- Interactions between the spheres determine the diverse nature and characteristics of environments.
- Human modifications can interrupt these interactions, leading to various impacts on environments.
Examples of Interactions
- Removing a tree can interrupt the interactions between the spheres.
- Urban developments and global climate change are examples of human modifications that can impact environments.
Natural Cycles and Systems
- Examples of natural cycles and systems include:
- Carbon Cycle
- Nitrogen Cycle
- Water Cycle
- Oxygen Cycle
- Nutrient Cycle
- Ecological Succession
- Rock Cycle
- Weather Systems
- Global air and water currents
- Weathering
- Erosion
- Deposition
Local Level Interactions
- Soil erosion can lead to tree death due to the tree's dependence on soil for survival.
- The tree and soil belong to the Biosphere and Lithosphere respectively.
- The tree interacts with other spheres, such as the Atmosphere and Hydrosphere, through processes like photosynthesis and water absorption.
