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.

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.
