Structure and Characteristics of the Sun
Transcript of Structure and Characteristics of the Sun
consists of hydrogen. While the rest is mostly helium. Convection zone Radioactive zone Chromosphere Core Photosphere Is considered to extend from
the center to about 0.2 to 0.25
It is the hottest part of
the Sun and of the
Solar System. Is a layer of a star's interior
where energy is primarily
transported toward the exterior
by means of radiative diffusion,
rather than by convection. Is the range of radii in which
energy is transported primarily
by convection. In the radiation
zone, energy is transported
by radiation. Is the region from which externally received light originates. Is the second of the three main layers in the Sun's atmosphere and is roughly 2,000 kilometers deep. It sits just above the photosphere and just below the solar transition region. Prominence Granules Sunspot Corona Is a type of plasma "atmosphere" of the Sun or other celestial body, extending millions of kilometers into space, most easily seen during a total solar eclipse, but also observable in a coronagraph. Temporary phenomena on the
photosphere of the Sun that appear
visibly as dark spots compared to
surrounding regions. The grainy appearance of the solar
Caused by convection currents of
plasma within the Sun's
convective zone. Is a large, bright feature extending outward from the Sun's surface, often in a loop shape. Hydrogen 73.46%
Sulfur 0.04% Photospheric
composition by mass Sun's life cycle The Sun was formed about 4.57 billion years ago. That consisted mostly of hydrogen and helium and which probably gave birth to many other stars. From the collapse of part of a giant molecular cloud. Solar eclipse Occurs when the Moon passes in front of the Sun as seen from the Earth. A total solar eclipse occurs when the Earth intersects the umbra portion of the Moon's shadow.
