The thermosphere contains an appreciable concentration of elemental sodium located in a 10-kilometre (6.2 mi) thick band that occurs at the edge of the mesosphere, 80 to 100 kilometres (50 to 62 mi) above Earth's surface. The sodium has an average concentration of 400,000 atoms per cubic centimeter.

Ocean View is a coastal region in the independent city of Norfolk, Virginia in the United States.It has several miles of shoreline on the Chesapeake Bay to the north, starting with Willoughby Spit to the west and the Joint Expeditionary Base -- Little Creek in the independent city of Virginia Beach on the east.
Relationship of the atmosphere and ionosphere. The ionosphere (/ aɪ ˈ ɒ n ə ˌ s f ɪər /) [1] [2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere.
From the Earth's surface to the top of the stratosphere (50km) is just under 1% of Earth's radius. The exosphere is a thin, atmosphere-like volume surrounding a planet or natural satellite where molecules are gravitationally bound to that body, but where the density is so low that the molecules are essentially collision-less.

Moho Discontinuity– The line between the crust and the Earth's mantle. Earth's mantle – The part of the interior of the planet Earth between the crust and the core. By diffusion of seismic waves Lithosphere – The rigid, outermost shell of a terrestrial-type planet or natural satellite that is defined by its rigid mechanical properties.
Tasmania, with capital Hobart, is off the coast of Victoria, across the Bass Strait. The Indian Ocean is to the west and northwest, the South Pacific Ocean to the east, the Southern Ocean to the south, and the Tasman Sea to the southeast. The Great Australian Bight to the south and the Gulf of Carpentaria to the north are the major bays.
GEBCO is the only intergovernmental body with a mandate to map the whole ocean floor. At the beginning of the project, only 6 per cent of the world's ocean bottom had been surveyed to today's standards; as of June 2022, the project had recorded 23.4 per cent mapped. About 14,500,000 square kilometres (5,600,000 sq mi) of new bathymetric data ...
The South Temperate Zone, between the Tropic of Capricorn at 23°26′09.7″ S and the Antarctic Circle at 66°33′50.3″ S, covers 25.99% of Earth's surface. The South Frigid Zone, from the Antarctic Circle at 66°33′50.3″ S and the South Pole at 90° S, covers 4.12% of Earth's surface. Earth's climatic zones
