What is chromosphere in sun?

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 is above the photosphere, the visible “surface” of the Sun.

How hot is the chromosphere?

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.

What is the color and temperature of the 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 heats the chromosphere and corona to high temperatures?

How do astronomers think the solar chromosphere and corona gets heated to their high temperatures? Magnetic fields carry heat outward from lower layers.

What is hotter than the sun?

In terms of temperature, which of the following is hottest? And the answer: lightning. According to NASA, lightning is four times hotter than the surface of the sun. The air around a stroke of lightning can peak at 50,000 degrees Fahrenheit, while the surface of the sun is around 11,000 degrees.

Is the chromosphere heated by the corona?

In the chromosphere, almost all the mechanical energy flux supplied to the outer solar atmosphere by magneto-convection is converted into heat and radiation, leaving a small amount to power the solar wind and the hot corona: the chromosphere requires over 30 times more energy than the corona and heliosphere combined.

Why is the Sun’s surface so hot?

The core of the sun is so hot and there is so much pressure, nuclear fusion takes place: hydrogen is changed to helium. Nuclear fusion creates heat and photons (light). The sun’s surface is about 6,000 Kelvin, which is 10,340 degrees Fahrenheit (5,726 degrees Celsius).

What is the temperature at the surface of the Sun?

The surface of the Sun is a mere 5,800 Kelvin, but down at the core of the Sun, the temperatures reach 15 million Kelvin.

How hot is the Sun Fahrenheit?

The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius). The temperature of the Sun also rises from the surface outward into…

What is the structure of the Sun?

The structure of the sun is made up of four layers. At the very center is the dense, hot core. Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere.

What is the Sun’s Solar System?

comprising 99.8% of the system’s mass.
