Problem Analysis:
The task involves filling in the blanks related to the structure and processes of the Sun. The provided words are:
solar flares, convective, heat, corona, photosphere, radiative, core, chromosphere, light. We need to match these terms with the correct parts of the Sun's structure and processes.
Solution:
#### 1.
Labeling the Diagram:
The diagram shows different layers of the Sun. Let's identify each layer based on its position and function:
-
Core: This is the innermost part of the Sun where nuclear fusion occurs.
-
Radiative Zone: This is the region just outside the core where energy is transported by radiation.
-
Convective Zone: This is the outermost layer of the interior where energy is transported by convection.
-
Photosphere: This is the visible surface of the Sun.
-
Chromosphere: This is a thin layer above the photosphere.
-
Corona: This is the outermost layer of the Sun's atmosphere.
#### 2.
Filling in the Blanks:
Now, let's fill in the blanks using the provided words:
1.
The _______ is where hydrogen is converted to helium by fusion.
-
Core: This is the innermost part of the Sun where nuclear fusion occurs.
2.
Nuclear fusion produces ______ and ______.
-
Heat and
light: Nuclear fusion releases both heat and light energy.
3.
Light moves from the core into the ________ zone.
-
Radiative: In this zone, energy is transported by radiation.
4.
Gases continually heat and cool in the _________ zone.
-
Convective: In this zone, energy is transported by convection.
5.
Eventually, heat and light break through the ___________.
-
Photosphere: This is the visible surface of the Sun where light escapes.
6.
Fiery swirls called ______ ______ shoot out when magnetic energy builds up at the surface.
-
Solar flares: These are eruptions of magnetic energy that release intense bursts of radiation.
7.
The _______ is hotter than the surface of the Sun.
-
Corona: Surprisingly, the Sun's corona (outer atmosphere) is much hotter than its surface.
Final Answer:
-
Core: Where hydrogen is converted to helium by fusion.
-
Heat and
light: Produced by nuclear fusion.
-
Radiative: Zone where light moves from the core.
-
Convective: Zone where gases continually heat and cool.
-
Photosphere: Surface where heat and light break through.
-
Solar flares: Fiery swirls caused by magnetic energy buildup.
-
Corona: Hotter than the surface of the Sun.
