Understand the definitions of the terms provided in the question: Hydrosphere refers to all water on Earth, Lithosphere refers to the solid outer layer of Earth, Atmosphere refers to the layer of gases surrounding Earth, and Biosphere refers to the regions of Earth where life exists.
Recognize that the question is asking for the term that encompasses all areas where life exists, including land, water, and air.
Recall that the Biosphere is the term specifically used to describe the part of Earth where life exists, integrating land (Lithosphere), water (Hydrosphere), and air (Atmosphere).
Eliminate the incorrect options based on their definitions: Hydrosphere is limited to water, Lithosphere is limited to land, and Atmosphere is limited to air. None of these individually describe the entirety of life-supporting regions.
Conclude that the correct term describing the part of Earth in which life exists, including land, water, and air, is Biosphere.
