What is above the photosphere of the Sun?
Chromosphere – The chromosphere is a layer in the Sun between about 250 miles (400 km) and 1300 miles (2100 km) above the solar surface (the photosphere).
What is the thinnest layer of the Sun?
Compared to the radius of the Sun, which is nearly 700 thousand kilometers (more than 400 thousand miles), the chromosphere is a very thin layer.
What is immediately above the photosphere?
The photosphere is much cooler than the Sun’s core, which has a temperature well above 10 million degrees. The area of the Sun’s interior immediately below the photosphere is called the convection (or convective) zone. The lower section of the Sun’s atmosphere, the chromosphere, lies above the photosphere.
What are the 3 layers of the Sun inside the photosphere?
The main part of the Sun has three layers: the core, radiative zone, and convection zone. The Sun’s atmosphere also has three layers: the photosphere, the chromosphere, and the corona. Nuclear fusion of hydrogen in the core of the Sun produces tremendous amounts of energy that radiate out from the Sun.
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 happens in the chromosphere of the Sun?
NASA/Marshall Solar Physics. 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).
How thick is the photosphere?
about 300 km thick
The photosphere is about 300 km thick. Most of the Sun’s visible light that we see originates from this region. The chromosphere is about 2000 km thick.
How hot is the chromosphere of the Sun?
about 36,000 degrees F.
the chromosphere is the innermost atmospheric layer. It is just above the photosphere. Here the temperature begins to rise again, to about 36,000 degrees F. Above the chromosphere is the transistion layer, where temperatures increase 6000 to over half-a-million degrees.
Why is the photosphere thin?
Simply put, there is too little matter to emit much light. This leaves a thin layer in between, about 500 km thick, where the gas is dense enough to emit an intense thermal radiation spectrum, yet not so opaque that we cannot see the light emanating from it.
What is photosphere chromosphere and corona?
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.
What happens on the chromosphere?
What is the photosphere of the sun quizlet?
Definition: The photosphere is the visible surface of the sun.
What is the lowest layer of the Sun’s atmosphere called?
The lowest layer of the sun’s atmosphere is the photosphere — the innermost layer that we can observe directly. It takes about eight minutes for sunlight to reach Earth. The temperature of the photosphere ranges from 11,000 degrees Fahrenheit (6,125 degrees Celsius) at the bottom to 7,460 F (4,125 C) at the top.
How far above the Sun is the chromosphere?
The chromosphere extends for about 2,000 kilometers (1,200 miles) above the visible surface of the Sun. Compared to the radius of the Sun, which is nearly 700 thousand kilometers (more than 400 thousand miles), the chromosphere is a very thin layer. The chromosphere is above the photosphere, the visible “surface” of the Sun.
What does the Sun look like from the outside?
The Sun may look like just a mass of incandescent gas (plasma, really), but it’s actually broken up into layers. The chromosphere is relatively thin region of the Sun that’s just above the photosphere. The photosphere is the region of the Sun that we see. It measures an average temperature of almost 5,800 kelvin and produces the visible radiation.
What is the visible surface of the Sun called?
The photosphere is the visible surface of the Sun. The solar atmosphere includes the chromosphere and corona. What are the “parts” of the Sun? Scientists who study the Sun usually divide it up into three main regions: the Sun’s interior, the solar atmosphere, and the visible “surface” of the Sun which lies between the interior and the atmosphere.
