Definitions of Key Terms

Environment: The collective term for social, economic, biological, physical, and chemical factors impacting living organisms.

Types of Environment

Natural Environment: Composed of elements like air, water, soil, land, forests, and wildlife.
Anthropogenic Environment: Human-altered environments designed for specific purposes, such as agricultural fields and gardens.

Spheres of Earth

Lithosphere: Encompasses all land masses, including solid rocks and molten materials; includes crust, mantle, outer core, and inner core; categorized into igneous, sedimentary, and metamorphic rocks.
Hydrosphere: Involves all forms of water (gaseous, liquid, and solid), with natural features like rivers, lakes, oceans, and glaciers; influences Earth's temperature and climate.
Atmosphere: Comprises air, mainly nitrogen (78%) and oxygen (21%), along with trace gases; divided into layers: troposphere, mesosphere, thermosphere, exosphere.
Biosphere: The realm of living organisms on Earth, including animals, plants, and microorganisms; interacts with lithosphere, hydrosphere, and atmosphere; contains diverse biomes like forests, deserts, and aquatic ecosystems.
