The biosphere is the biggest sphere among all.
There is only one biosphere. The biosphere is the culmination of all life on Earth, hence, sphere.
Where the Earth is concerned, humans live in the 'biosphere', together with all other living matter. Overlapping the biosphere, are the hydrosphere, and the atmosphere, and below us , inside the Earth, is the lithosphere. Above the atmosphere is the stratosphere, and then the ionosphere. NB All theses 'spheres' overlap to some extent.
No, a sphere and a circle are different geometric shapes. A sphere is a three-dimensional object with all points equidistant from the center, while a circle is a two-dimensional shape with all points equidistant from the center. In other words, a circle is a flat, circular shape, while a sphere is a three-dimensional, round object.
The radius of a sphere is equal distance from the center of the sphere to all points within the sphere.
