biosphere (zone supporting

Natural Environment Domains:
Lithosphere: Earth's solid crust consisting of rocks, minerals, and
soil; provides forests, land for agriculture, and settlements.
Hydrosphere: Comprises various water sources, rivers, lakes, seas,
oceans; vital for all life.
Atmosphere: Thin layer of air surrounding Earth, containing gases,
dust, and water vapor; influences weather and climate.
Biosphere: Narrow zone where land, water, and air interact to
support life.
