Some of the prisoners were released to accompany Columbus. On 12th October 1492, Columbus spotted the land and called it Spain. The Tainos noticed it from behind the lush green trees. The Tainos believed as these white people with ships landed from heaven.
The ionosphere is that region of the upper atmosphere of a planet where charged particles (electrons and ions) of thermal energy are present, which are the result of ionization of the neutral atmospheric constituents by electromagnetic and corpuscular radiation.he termination of the ionosphere is then the indirect result of the solar wind interaction; e. g., in the case of Earth, represented by the boundary between solar-wind induced convective motions inside the magnetosphere and the co-rotating ionospheric plasma called the plasmapause.
The ionosphere isn't its own separate layer, but is actually the name given to the atmosphere from about 37 miles (60 km) to 620 miles (1,000 km) high. (It includes the top-most parts of the mesosphere and all of the thermosphere and exosphere.) Gas atoms drift into space from here.
