Show answer & explanation
Correct answer: A
The solid portion of the Earth on which we live is known as the lithosphere. Lithosphere — the solid, rigid outer shell of the Earth, including the crust and the uppermost mantle. This is the layer where we live.
Biosphere — the region where life exists, encompassing parts of the land, water, and air where organisms live.
Troposphere — the lowest layer of the atmosphere, composed of air, not a solid layer.
Ecosphere — a term referring to the global ecosystem or interactions between organisms and their environment, not the solid surface.
Therefore, the correct term for the solid portion of the Earth on which we live is the lithosphere.
