Study Notes
Environmental Science Overview
- Interdisciplinary field combining various scientific branches to address environmental issues.
- Environmental studies focus on social sciences to analyze human-environment interactions.
- Ecology examines the relationships between organisms and their environments.
- Environmental engineering involves evaluating man-made effects on the environment and developing preservation solutions.
Definition of Environment
- Derived from the French word "ENVIRONNER," meaning to encircle or surround.
- Encompasses social, economic, biological, physical, and chemical factors that influence organism growth and welfare.
- Includes both natural and human-affected surroundings affecting organisms throughout their lifespan.
Types of Environment
- Natural Environment: Features no man-made components; consists of air, water, soil, land, forests, wildlife, flora, and fauna.
- Anthropogenic Environment: Involves human-created or altered surroundings.
Natural Environment Characteristics
- Dynamic and self-regulating, exhibiting mechanisms like counter-balancing.
- Composed of four main subdivisions: Lithosphere, Hydrosphere, Atmosphere, and Biosphere.
Segments of the Natural Environment
- Atmosphere: A vast ocean of air surrounding the Earth.
- Hydrosphere: All water on Earth, encompassing oceans, rivers, lakes, and underground water.
- Lithosphere: Outer layer of the Earth, including the crust and rigid outermost mantle.
- Biosphere: Zones on Earth where life exists, integrating all living organisms.
Atmospheric Composition
- Composed primarily of nitrogen (78%) and oxygen (21%).
