Study Notes
Environment and Components
- The abiotic environment excludes living organisms and focuses on non-living elements.
- Energy in the environment primarily comes from the sun.
- Energy is released back into the atmosphere as heat.
- An example of developmental impact on the hydrosphere is pollution and habitat destruction.
- The zone that includes air, water, and soil is called the environment.
- Types of environments do not include artificial environments.
Social and Physical Environment
- The social environment encompasses cultural, economic, and social interactions.
- The physical environment is often referred to as the natural environment.
- The term "environment" is derived from the old French word “ënviro,” meaning "to encircle" or "surround."
Environmental Issues and Trends
- Acid rain impacts include soil degradation and water quality decline; it does not directly cause increased biodiversity.
- Major population growth is driven by advancements in medicine, agriculture, and sanitization.
- The 4Rs—Reduce, Reuse, Recycle, and Recover—are essential for sustainable practices.
- Not all materials are recyclable, and common examples include certain types of plastics.
Ecosystems and Biodiversity
- The food chain in an ecosystem is vital for maintaining ecological balance.
- The ozone layer protects life from harmful UV radiation.
- Interdependence among organisms and their environment is termed ecological interaction.
- Biotic and abiotic components together form an ecosystem.
Climate and Atmospheric Dynamics
- "Tundra" represents a cold type of ecosystem with specific flora and fauna.
- The height of the ozone layer above Earth's surface varies, generally found at 10 to 30 miles high.
- Greenhouse gases, like carbon dioxide and methane, trap heat in the atmosphere, a process essential for regulating Earth's temperature.
Pollution and Environmental Concerns
- Radioactive waste from nuclear reactors poses significant environmental risks.
- Acid rain comprises sulfuric and nitric acids resulting from industrial emissions.
- The biosphere represents areas on Earth where life can exist, incorporating both terrestrial and aquatic ecosystems.
Renewable Resources and Energy
- Solar energy intercepted by Earth is measured in units like megajoules or gigajoules.
- Renewable energy sources are continuously replenished, such as solar, wind, and hydroelectric power.
- Tidal energy generates electricity through the movement of ocean tides and currents.
Conservation and Resource Management
- Forests play a crucial role in protecting biodiversity, managing water cycles, and conserving soil.
- Resource depletion occurs when natural resources are consumed faster than they can be replenished.
- Conservation strategies focus on sustainable use and management of natural resources.
