Presentation transcript:

Question 1: Except for a thin layer at the bottom of the chromosphere, the sun’s atmosphere … Review Quiz No. 9 :60 1.gets persistently hotter further out. 2.has a fairly constant temperature throughout. 3.gets persistently cooler further out. 4.has an oscillating temperature structure with height. 5.shows no persistent trend with height.

Question 2: The apparent surface of the sun, from which we see most of its light emerging, is called the :45 1.corona. 2.chromosphere. 3.photosphere. 4.convection zone. 5.core.

Question 3: The sun is producing its energy via :45 1.chemical burning of hydrogen (2 H + O → H 2 O) 2.nuclear fission of heavier elements, mostly helium, into hydrogen. 3.nuclear fusion of hydrogen into helium. 4.nuclear fission of heavy elements (e.g., Uranium) into lighter nuclei. 5.nuclear fusion of helium into heavier elements.

Question 4: Near the core of the sun, heat produced in the hydrogen-fusing core is transported outward via :45 1.prominences. 2.jet streams. 3.thermal conduction. 4.radiative energy transport. 5.convection.
