II UTILITIJI
Mention the spheres of the Earth.
Answers
Magnetosphere – The region around an astronomical object in which charged particles are affected by its magnetic field
Atmosphere, the gases that surround the Earth (its air)
By altitude
Exosphere – The outermost layer of an atmosphere
Exobase – The lower boundary of the exosphere
Ionosphere – The ionized part of Earth's upper atmosphere
Thermopause – The upper boundary of the thermosphere
Thermosphere – The layer of the atmosphere above the mesosphere and below the exosphere
Mesopause – The temperature minimum at the boundary between the mesosphere and the thermosphere
Mesosphere – The layer of the atmosphere directly above the stratosphere and below the thermosphere
Stratopause – The upper boundary of the stratosphere
Stratosphere – The layer of the atmosphere above the troposphere
Ozone layer – The region of Earth's stratosphere that absorbs most of the Sun's UV radiation
Tropopause – The boundary of the atmosphere between the troposphere and stratosphere
Planetary boundary layer – The lowest part of the atmosphere, directly influenced by contact with the planetary surface
By air turbulence
Heterosphere – Upper parts of the amosphere in which the component gases are not well mixed
Turbopause – The altitude in the Earth's atmosphere below which turbulent mixing dominates
Homosphere – Lower parts of the atmosphere in which the component gases are well mixed
Biosphere – The global sum of all ecosystems on Earth
Anthroposphere – The part of the environment that is made or modified by humans for use in human activities and human habitat
Noosphere (rare) – The sphere of human thought
Cryosphere – Those portions of Earth's surface where water is in solid form
Hydrosphere – The combined mass of water found on, under, and above the surface of a planet, minor planet or natural satellite
Pedosphere – The outermost layer of the Earth that is composed of soil and subject to soil formation processes
Geosphere/Solid Earth – A collective name for the lithosphere, the hydrosphere, the cryosphere, and the atmosphere
Lithosphere – The rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties
Crust (geology) – The outermost solid shell of a rocky planet, dwarf planet, or natural satellite
Asthenosphere – The highly viscous, mechanically weak and ductile region of the Earth's upper mantle
Mesosphere – The part of the Earth's mantle below the lithosphere and the asthenosphere, but above the outer core
Earth's mantle – The part of the interior of the planet Earth between the crust and the core
Earth's core – The inner part of the planet, formed by differential buoyancy of the component materials causing the denser materials to accumulate nearer to the centre.
Inner core – The innermost part of the Earth, a solid ball of iron-nickel alloy
Outer core – A fluid layer composed of mostly iron and nickel between Earth's solid inner core and its mantle
