Study Notes
Environment and Its Scope
- The environment encompasses all that is around us, including physical, chemical, biological, and social elements. Each element plays a significant role in natural and human systems.
- Key scopes of the environment include the atmosphere, hydrosphere, lithosphere, and biosphere, which interact with each other in complex ways.
Composition of the Environment
- The environment consists of four main spheres: the atmosphere (air), hydrosphere (water), lithosphere (land), and biosphere (living organisms).
- These spheres work together to create the ecosystem and affect life on Earth.
Influences on Humans
- The lithosphere (land) and atmosphere (air) directly influence human activities, affecting climate, weather patterns, and natural resources available for use.
Composition of Dry Air
- The majority of dry air is composed of nitrogen (approximately 78%), oxygen (around 21%), and trace amounts of other gases such as argon and carbon dioxide.
Hydrosphere
- The hydrosphere includes all water bodies on Earth, such as oceans, rivers, lakes, and groundwater. It plays a crucial role in climate regulation and supports all forms of life.
Lithosphere
- The lithosphere comprises the Earth's crust and the uppermost part of the mantle. It includes rocks, soil, and landforms, serving as the foundation for ecosystems and human infrastructure.
Biosphere
- The biosphere is the global sum of all ecosystems, encompassing all living organisms and their interactions with the environment. It extends from the deepest ocean floors to the highest mountains.
Atmosphere
- The atmosphere is a layer of gases surrounding the Earth, essential for life as it provides oxygen, protects against harmful solar radiation, and regulates temperature through the greenhouse effect.
