Is the first part of the sun called the photosphere?

The boundary between the Sun's interior and the solar atmosphere is called the photosphere. It is what we see as the visible "surface" of the Sun. The photosphere is not like the surface of a planet; even if you could tolerate the heat you couldn't stand on it.

What is the first part of the Sun?

Photosphere. The material that reaches the top of the convection zone cools by giving of light. This region of the Sun is the first part of the Sun that is visible to us and we call it the photosphere. This is where the light we see from the Sun originates.

What is the first layer of the Sun 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.

What is the photosphere of the Sun?

Photosphere - The photosphere is the deepest layer of the Sun that we can observe directly. It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that.

What are the 7 layers of the Sun in order?

It is composed of seven layers: three inner layers and four outer layers. The inner layers are the core, the radiative zone and the convection zone, while the outer layers are the photosphere, the chromosphere, the transition region and the corona.

What is the photosphere made of?

The Sun's photosphere is around 100 kilometers thick, and is composed of convection cells called granules—cells of plasma each approximately 1000 kilometers in diameter with hot rising plasma in the center and cooler plasma falling in the narrow spaces between them, flowing at velocities of 7 kilometer per second.

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).

What is the Sun's photosphere quizlet?

PHOTOSPHERE. The Sun's visible surface. The layer in the Sun from which visible photons most easily escape. chromosphere. It is a thin, hot layer of gas just above the photosphere.

What does the word chromosphere mean?

Definition of chromosphere

: the region of the atmosphere of a star (such as the sun) between the star's photosphere and its corona.

Why is the chromosphere hotter than the photosphere?

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. ... Even though it's more distant from the center of the Sun, the chromosphere is hotter than the photosphere.

What layer of the Sun is the chromosphere?

The chromosphere is the second most outer layer of the Sun. Several thousand kilometres thick, it resides above the photosphere and beneath the corona. Due to its low density, it is relatively transparent, resulting in the photosphere being regarded as the visual surface of the Sun.

What layer is the chromosphere?

The chromosphere is above the photosphere, the visible "surface" of the Sun. It lies below the solar corona, the Sun's upper atmosphere, which extends many thousands of kilometers above the chromosphere into space. The plasma (electrically charged gas) in the chromosphere has a very low density.

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.

How thick is the photosphere?

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?

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.
