The Sun | Earth Sciences Quiz - Quizizz Which of the following is not a method astronomers use to determine the physical conditions inside the Sun? b. C) Energy slowly leaks outward through the radiative diffusion of photons that repeatedly bounce off ions and electrons. Which of the following is currently a big mystery to solar physicists? B Save my name, email, and website in this browser for the next time I comment. They are distributed approximately uniformly over the Sun's surface both in position and in time. How do we know what is going on in the center of the Sun so well if we cannot see it or send spacecraft to it? Sunspots occur in a regular cycle, with the number of sunspots occurring in any given year peaking and waning. c. As you approach the Sun, you will enter the corona, an extremely hot layer of gas, but so low in density that you won't really feel how hot it is. B) about 700,000 kilometers (the radius of the Sun) If an electric hair dryer uses 2,400 J of" energy in 2 s, what is its power? causes lung irritation, asthma, and susceptibility to respiratory illness in humans. Which of the following statements about the sunspot cycle is not true? The Suns strong magnetic field gets twisted and tangled due to its convection, forming visible sunspot groups. And at minimum you have a minimum number of sunspots, and at maximum, a maximum. b. FAQ: How Does the Solar Cycle Affect Earth's Climate? | NASA A) photosphere D . ________ refers to changes in daylength and the Sun's altitude over the course of the year. 10. MID-TERM #1 Chapters 1,2,3 Flashcards by Drew Holland | Brainscape Glacial moraines show when and where previous episodes of glaciation occurred. B The light radiated from the Sun's surface reaches Earth in about 8 minutes, but the energy of that light was released by fusion in the solar core about Which of the following is not true of sunspots? Two of the protons are ejected back into the solar material. C) The core would heat up, causing it to radiate so much energy that it would shrink even more. the parallel that is the farthest northern location for the subsolar point during the year. Another way that we can learn about the Sun is by capturing the particles in the solar wind that come from the Sun. Our Sun will end its life by becoming. 1) In the late 1800s, Kelvin and Helmholtz suggested that the Sun stayed hot thanks to gravitational contraction. A. C) The hydrogen gas in the Sun is balanced so that it never rises upward or falls downward. Magnetism is a physical quality mediated by a magnetic field that refers to the ability to create attracted and repulsive occurrences in other substances. List at least two ways the sunspot cycle affects us on Earth. A) The number of sunspots peaks approximately every 11 years. A) gravitational contraction of the Sun B With his observations of the phases of Venus, Galileo was able to figure out that the planet orbits the Sun, not the Earth as was the common belief in his time. C) magnetic fields trap ionized gases that absorb light. B a. What two pollutants react with water to produce acid rain? E. All radio signals pass through this region virtually unaffected. 6. E) The rate of nuclear fusion in the Sun peaks about every 11 years. is not associated with transportation *b. B) the linkage of numerous protons into long chains. What did Galileo discover? | Royal Museums Greenwich - Cutty Sark the monitoring of a distant object without physical contact.
