The sun's interior consists of
the core, the radiation zone, and the convection zone.
The sun's central region that produces an enormous amount of energy from nuclear fusion.
the process by which hydrogen atoms join together in the sun's core to form helium.
the middle layer of sun's interior characterized by very tightly packed gas when energy is transferred mainly in the form of electromagnetic radiation.
the outermost layer of the sun's interior where loops of gas form
The sun's atmosphere includes
the photosphere, the chromosphere, and the corona
the inner layer of sun's atmosphere that gives off visible light
the middle layer of sun's atmosphere (color sphere)
the outer layer of sun's atmosphere (crown) that extends into space
streams of electrically charged particles that emanate from the sun's corona
Features on or just above the sun's surface include
sunspots, prominences, and solar flares.
areas of gas on the sun's surface that are cooler than the gases around them.
Sunspots looks darker than the rest of the photosphere because
they are cooler and therefore give off less light than the surrounding photosphere.
huge, reddish loops of gas that link different parts of sunspot regions.
eruptions of gas from sun's surface that occur when the loops in sunspot regions suddenly connect.
rippling sheets of light caused by glowing gas currents (from solar flares/solar wind).
tell us about the brightness of the sun
tell us the trees age
less carbon is produced when the sun is at its brightest
when trees absorb more or less carbon, it shows in there rings
