Which layer of the Sun brings heat and energy to the surface?
Diagram of the Sun Surface: the photosphere layer is the most visible to the human eye. Here the temperature is only about 10,000 degrees F. This layer, which looks like a bright disk, sends light and heat to Earth.
Which zone contains hot gas moving up toward the surface with cooler gas moving down toward the center of the Sun?
The Convection Zone sun’s interior. Hot gases rise from the bottom of the convection zone and gradually cool as they approach the top. Cooler gases sink, forming loops of gas that move energy towards the sun’s surface, similar to a lava lamp.
What carries the Sun’s energy to the Sun’s surface?
Particles of light called photons carry this energy through a spherical shell called the radiative zone to the top layer of the solar interior, the convection zone. There, hot plasmas rise and fall like the ooze in a lava lamp, which transfers energy to the sun’s surface, called the photosphere.
What is the layer of the Sun through which energy is transferred away from the core by radiation?
Unit 4, Lesson 3: The Sun
|radiative zone||layer of the sun which energy is transferred away from the core by radiation|
|core||very dense center of the sun|
|nuclear fusion||process by which tow or more low-mass atomic nuclei fuse to form another, heavier nucleus.|
|radiation||when energy is transferred as electromagnetic waves|
Which layer of the Sun shoots out hot gases?
Chromosphere: This layer shoots out hot gases.
In which part of the Sun do gasses heat up and rise and then cool down and sink?
The convection zone is the outer-most layer of the interior. It extends from a depth of 200,000 km up to the visible surface of the Sun. Energy is transported by convection in this region.
What layer of atmosphere is the Sun in?
The sun’s atmosphere is made up of several layers, mainly the photosphere, the chromosphere and the corona.
What are the Suns layers?
The inner layers are the Core, Radiative Zone and Convection Zone. The outer layers are the Photosphere, the Chromosphere, the Transition Region and the Corona. IRIS will focus its investigation on the Chromosphere and Transition Region.
What region of the Sun is the hottest?
The core is at the center. It the hottest region, where the nuclear fusion reactions that power the Sun occur.
What makes up the top layer of the Sun?
Surrounding all of them is the sun’s surface layer, known as the photosphere. Above this lies the sun’s thin atmosphere, which is made up of the chromosphere and the corona. Most of the sun is made up of hydrogen in the form of a glowing-hot gas called plasma.
Where does the heat move in the Sun?
Vast bubbles of hot gas rise up through this zone to the surface, where they cool and sink again. This process allows heat to move from the sun’s heart to its outer surface. Radiative zone Radiative zone
How is the photosphere different from the rest of the Sun?
It is much less bright than the photosphere, so we can only see it if the rest of the sun is blotted out, for example during a solar eclipse. The photosphere is the layer of the sun we can see from the outside. It looks solid, but in fact it is a layer of gas around 300 miles (500km) thick.
What’s the temperature at the center of the Sun?
It reaches from the surface visible at the center of the solar disk to about 250 miles (400 km) above that. The temperature in the photosphere varies between about 6500 K at the bottom and 4000 K at the top (11,000 and 6700 degrees F, 6200 and 3700 degrees C).
