Option 2: Atmosphere - The atmosphere is the layer of gases surrounding the Earth. It is a key component of the physical environment.

Option 3: Lithosphere - The lithosphere refers to the Earth`s solid outer layer, including the crust and uppermost portion of the mantle. It is part of the physical environment.

Option 4: Hydrosphere - The hydrosphere includes all water on Earth, including oceans, lakes, rivers, groundwater, and glaciers. It is also a component of the physical environment.

Therefore, the correct answer is option 1, Hemisphere, as it does not belong to the physical environment. Alert - Correct answer should be: 1 Hemisphere is not a component of the physical environment.
