Question: Which Of The Sun’S Layers Are Most Smaller Stars Missing?

What is the photosphere of the sun quizlet?

photosphere.

the inner layer of the sun’s atmosphere that gives off its visible light.

chromosphere.

the middle layer of the sun’s atmosphere (reddish color).

What is Sun’s corona?

The Sun’s corona is the outermost part of the Sun’s atmosphere. The corona is usually hidden by the bright light of the Sun’s surface. … However, the corona can be viewed during a total solar eclipse. Our Sun is surrounded by a jacket of gases called an atmosphere.

Why is the corona hotter?

The sun’s corona gets trapped by magnetic field lines, which are likely responsible for heating the corona to millions of degrees.

Which is hotter sun or lava?

The sun is much hotter than lava. Surface temparature of the sun is 10,000 degrees F, while Lava averages only 2000 degrees F. … At its surface, the sun’s temperature is a 10,000° F! That’s about five times hotter than the hottest lava on Earth.

What is Sun’s corona made of?

Corona, outermost region of the Sun’s atmosphere, consisting of plasma (hot ionized gas). It has a temperature of approximately two million kelvins and an extremely low density. The corona continually varies in size and shape as it is affected by the Sun’s magnetic field.

What is the visible part of Sun called?

From the center out, the layers of the Sun are as follows: the solar interior composed of the core (which occupies the innermost quarter or so of the Sun’s radius), the radiative zone, and the the convective zone, then there is the visible surface known as the photosphere, the chromosphere, and finally the outermost …

What layer of the sun are we seeing in this photo?

photosphereThe photosphere is the lowest layer of the solar atmosphere. It is essentially the solar “surface” that we see when we look at the Sun in “white” (i.e. regular, or visible) light.

Which of the sun’s layers produces visible light?

photosphereThe lowest layer of the sun’s atmosphere is the photosphere. It is about 300 miles (500 kilometers) thick. This layer is where the sun’s energy is released as light.

What is the outermost layer of the sun?

PhotosphereThe outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region. More detail on the outer layers follows: Photosphere – The photosphere is the deepest layer of the Sun that we can observe directly.

What are earth’s layers?

Starting at the center, Earth is composed of four distinct layers. They are, from deepest to shallowest, the inner core, the outer core, the mantle and the crust. Except for the crust, no one has ever explored these layers in person.

Who can see a total solar eclipse?

Only viewers located in the path of the Moon’s full shadow, its umbra, can see a total solar eclipse. The Moon’s umbra travels eastward at about 1,700 km/h (1,056 mph). A total solar eclipse can last for several hours. Totality can range from a few seconds to 7.5 minutes.

What is the corona on the sun quizlet?

A region of turbulent plasma between a star’s core and its visible photosphere at the surface, through which energy is transferred by convection. … The sun’s corona is normally visible only during a total solar eclipse when it is seen as an irregularly shaped pearly glow surrounding the darkened disk of the moon.

What is the hottest layer in the sun’s atmosphere?

coronaThe outermost atmospheric layer is the corona, which gets really hot, almost 2,000,000 degrees F. This is where the solar wind begins. These layers can only be seen during total solar eclipses.

Which regions make up the Sun’s interior and surface select all of the answers that apply?

Select all of the answers that apply. photosphere corona core radiative zone chromosphere convective zone.

What is the surface of the sun that is visible to us?

photosphereThe 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 coldest layer of earth?

mesosphereLocated between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).

Which is the hottest layer of the earth?

inner coreThe inner core is the hottest layer, above 9000 Fahrenheit and it is 1250 km thick! Crust: The Earth’s thinnest layer! Mantle: The Earth’s thickest layer!

What are the 7 layers of the sun?

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 inside of the sun like?

The sun is a big ball of gas and plasma. Most of the gas — 91 percent — is hydrogen. It is converted into energy in the sun’s core. The energy moves outward through the interior layers, into the sun’s atmosphere, and is released into the solar system as heat and light.

What was the first layer of the earth?

CrustThe first layer is called the Crust and it is the thinnest layer of the Earth. The second is the Mantle and it is the thickest layer of earth’s crust, it’s divided into two parts but the mantle is made up into one. The third layer is the Outer Core and the Outer Core is made up by composed iron and liquid.

Which part of Earth is the coolest?

East Antarctic PlateauThe coldest place on Earth is on a frozen ice ridge of the East Antarctic Plateau between the summits Dome Argus and Dome Fuji, where researchers measured temperatures that reached minus 148 degrees Fahrenheit (minus 100 degrees Celsius).
