What is the chromosphere of the Sun quizlet?
Definition: The chromosphere is outside of the photosphere and is approximately 2,500 km thick and has a temperature of nearly 30,000 Kelvin. Sentence with extra information: The chromosphere is visible only during a solar eclipse when the photosphere is blocked.
What is the chromosphere of the Sun?
chromosphere, lowest layer of the Sun’s atmosphere, several thousand kilometres thick, located above the bright photosphere and below the extremely tenuous corona.
What are the photosphere chromosphere and corona quizlet?
The photosphere is the normally visible surface of the Sun and can be observed with visible light. The chromosphere and corona are best observed during total eclipses or artificial eclipses produced by coronagraphs.
What are the properties of chromosphere?
The chromosphere is an irregular layer above the photosphere where the temperature rises from 6000°C to about 20,000°C. At these higher temperatures hydrogen emits light that gives off a reddish color (H-alpha emission).
What is the first layer of the Sun called?
The sun’s photosphere The photosphere is the lowest layer of the sun’s atmosphere — the innermost layer we can observe directly. The term photosphere means “sphere of light” and is the layer where most of the sun’s energy is emitted.
What is the proton proton chain reaction describe this process quizlet?
The proton-proton chain takes the similar hydrogen nuclei and fuses them together to form the larger helium nucleus. Nuclear fission takes a larger nucleus and splits it into smaller nuclei.
How can the Sun’s chromosphere best be described?
The Sun’s chromosphere appears as a rim of red light during a solar eclipse. The lower region of the Sun’s atmosphere is called the chromosphere. Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse.
How are the photosphere chromosphere and corona related?
The Sun – our central star Beginning from the outside, they are: the corona – the outermost, hot shell of the atmosphere. the chromosphere – a transparent layer between the corona and the photosphere. the photosphere – the visible “surface” of the Sun.
Why is the chromosphere red?
The chromosphere appears red because of the large amount of hydrogen present. You can see this red color at the very edge of the Sun during a total solar eclipse. The most visible and impressive features of the chromosphere include filaments and prominences.
What does chromosphere mean in science?
The lower region of the Sun’s atmosphere is called the chromosphere. Its name comes from the Greek root chroma (meaning color), for it appears bright red when viewed during a solar eclipse. The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun.
How hot is the chromosphere of the Sun?
The temperature in the chromosphere varies between about 4000 K at the bottom (the so-called temperature minimum) and 8000 K at the top (6700 and 14,000 degrees F, 3700 and 7700 degrees C), so in this layer (and higher layers) it actually gets hotter if you go further away from the Sun, unlike in the lower layers.
