Generally, the Earth is divided into spheres which include the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air). The earth is divided into three layers based on chemical composition and these are the core, mantle and crust. In addition, the earth is also divided into physical properties which include lithosphere, athenosphere, mesosphere, outer core and inner core. Based on the given details, we can conclude that the atmosphere cannot be part of the lithosphere but instead, it is classified in a separate layer. The lithosphere only consists the outermost, rigid part of the Earth, which are the crust and the mantle. Hope this answer helps.

According to international convention, locations east of the Prime Meridian have positive longitudes while any point west of the Prime Meridian and before the International Date Line has a negative longitudinal value.
An alternative notion for writing coordinates in the Western Hemisphere is replacing the negative signs with the words <em>east </em>and <em>west </em>to avoid the negative and positive symbols and any possible associated confusion.
Explanation:
Heliocentrism is the astronomical model in which the Earth and planets revolve around the Sun at the center of the Solar System. Historically, heliocentrism was opposed to geocentrism, which placed the Earth at the center.
a cosmological model in which the Sun is assumed to lie at or near a central point (e.g., of the solar system or of the universe) while the Earth and other bodies revolve around it.
