Question

Quizplus · Accepted Answer

The biosphere is the narrow zone of the Earth's surface where life exists. It extends from the floor of the oceans to approximately 8 km into the atmosphere, encompassing all living organisms and their interactions with the other spheres (such as the hydrosphere, lithosphere, and atmosphere). Therefore, option D is the correct answer. Option A is incorrect because the lithosphere refers to the solid outermost layer of the Earth, not the biosphere. Option B is incorrect because there is no conclusive evidence of life on other planets in the solar system. Option C is incorrect because the biosphere is not isolated from the other inorganic spheres, but rather interacts with them.
