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.
A region of the Earth's atmosphere in which atoms are often ionized (electrically charged) by radiation from the sun. The ionosphere lies mostly in the lower thermosphere, from about 43 to 250 miles (69 to 402.5 kilometers) above the Earth.he upper layer of the atmosphere that lies above the stratosphere and is about 217 mi (350km) thick. 2. The area of the Earthâs atmosphere in which ionization caused by solar radiation affects the transmission of radio waves.
