Atmosphere of the Sun: Photosphere, Chromosphere & Corona The atmosphere of the sun is composed of several layers, mainly the photosphere, the chromosphere and the corona. It's in these outer layers that the sun's energy, which has bubbled up from the sun's interior layers, is detected as sunlight.

THE SUN The atmosphere’s outer layer is called the corona (crown). In ultraviolet light, it is revealed to be full of loops of hot gas. These coronal loops may rise as high and as wide as 500,000 km (300,000 miles). The inner layer of the Sun’s atmosphere is a pinkish colour and is called the chromosphere (colour-sphere).rom Earth, observers cannot usually see the corona, or outer atmosphere of the Sun, because the photosphere (surface) is so bright. During a total eclipse, however, the moon blocks out the surface and we can see the Sun’s atmosphere.

How to Study for and Take a Short Answer or Essay Test Be aware of how much time you have to take the test, and how many questions you have to answer in that time. You don’t want to spend half your time answering one question (unless your test has two questions). Keep in mind what the motivation of your instructor is in giving a short answer/ essay format test.

- The extended outer atmosphere of the Sun is called the corona. It has a temperature of millions of degrees, but it is 10 billion times less dense than the atmosphere of the Earth at sea level.

Sunspots and the rotation of the Sun The sunspots are cooler places on the photosphere, that is the superficial layer of the Sun, where the light that goes out from the Sun forms : they appear, evolve and disappear. The number of spots depends on an 11-years activity cycle of the Sun.

- Thus, the atmosphere blocks about 77% of the Sun's UV, almost entirely in the shorter UV wavelengths, when the Sun is highest in the sky (zenith). Of the ultraviolet radiation that reaches the Earth's surface, more than 95% is the longer wavelengths of UVA, with the small remainder UVB. There is essentially no UVC. The fraction of UVB which remains in UV light after passing through the atmosphere is heavily dependent on cloud cover and atmospheric conditions.

- The chromosphere is relatively thin region of the Sun that’s just above the photosphere. Plasma on the surface of the Sun. Image credit: Hinode. 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.This is the point where photons generated inside the Sun can finally leap out into space. The chromosphere measures just 2,000 km, and it’s just outside the photosphere.he photosphere is the region of the Sun that we see.

"The Photosphere - the ""Surface"" of the Sun" The Photosphere-the Surface of the Sun. Most of the energy we receive from the Sun is the visible (white) light emitted from the photosphere. The photosphere is one of the coolest regions of the Sun (6000 K), so only a small fraction (0.1%) of the gas is ionized (in the plasma state). The photosphere is the densest part of the solar atmosphere, but is still tenuous compared to Earth's atmosphere (0.01% of the mass density of air at sea level).

- The suns visable surface is called photosphere. There is an area above this photosphere that is named the reversing layer that extends about 300 miles. This reversing layer is … responsible for most of the absorption lines that show in the specturm of the sun. The two outermost layers of the sun are the chromosphere and the corona.

The Sun: Earthâs Primary Energy Source Once the Sun’s energy reaches Earth, it is intercepted first by the atmosphere. A small part of the Sun’s energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the Sun’s energy is reflected back to space by clouds and Earth’s surface. Most of the radiation, however, is absorbed by Earth’s surface.

Earthâs Sun: Facts About the Sunâs Age, Size and History The photosphere is the lowest layer of the sun's atmosphere, and emits the light we see. It is about 300 miles (500 km) thick, although most of the light comes from its lowest third. Temperatures in the photosphere range from 11,000 F (6,125 C) at bottom to 7,460 F (4,125 C) at top.he photosphere is the lowest layer of the sun's atmosphere, and emits the light we see.

Describe features of the Sun that are always present. Why are they there all the time? The sun has a thin reddish layer of gas above the photosphere called the Chromosphere, and that is always present, although it take a total solar eclipse or a very special filter that lets through only the light of Hydrogen gas in order to see the chromosphere.

- The sun is mostly composed of the elements hydrogen (H) and helium (He). By mass the composition of the sun is 75 percent hydrogen and 25 percent helium. Various metals make up less than 0.1 percent of the mass of the sun. The temperature of the sun’s surface is about 10,340 degrees Fahrenheit (5,726 degrees Celsius).

(f). The Nature of Radiation The Sun emits most of its radiation in a wavelength band between 0.1 and 4.0 micrometers (µm). EARTH Figure 6f-3: Spectrum of the Earth. The Earth emits most of its radiation in a wavelength band between 0.5 and 30.0 micrometers (µm).he Sun emits only a portion (44 %) of its radiation in zone. Solar radiation spans a spectrum from approximately 0.1 to 4.0 micrometers. The band from 0.1 to 0.4 micrometers is called ultraviolet radiation. About 7% of the Sun's emission is in this wavelength band.
