Troposphere
The biosphere contains all of Earth's living things.
I think it's the atmosphere
Earth's four major spheres are the lithosphere, biosphere, atmosphere, and hydrosphere. The lithosphere contains all of the cold, hard solid land of the planet's crust The biosphere contains all the planet's living things. The atmosphere contains all of the air in the Earth system The hydrosphere contains all the solid, liquid, and gaseous water of the planet.
The Milky Way, parts of which we can see from Earth curving around us.
It is represented as a disk, but is really a sphere.
The Solar system. That is the system of the star Sol.
Of the eight planets in our solar system, Earths is the fifth largest or the fourth smallest.
what system contains galaxies
A planet is a celestial body that orbits around a star, has sufficient mass for its self-gravity to overcome rigid forces so that it assumes a nearly round shape, and has cleared its orbit of other debris.
Neptune is one of the gas giants that orbit in the outer solar system. It is spherical, like the other planets. Gravity has pulled together all the material that composes this odd planet, and it is gravity that determines its shape. One determinate of whether or not a body is a planet is whether or not gravity has rounded its structure.
