O A. 11 year solar sunspot cycles change the amount of radiation given off by the Sun.
O B. As the Sun rotates more energy is scattered to space and less is retained on the surface.
O C. Cycles of solar flares and prominences heat and cool the layers below the Sun's surface.
O D. Solar energy is affected by the core output of photons.

- 21. While observing the Sun, you note a large number of sunspots. What can you conclude? This is a period of low solar activity. Earth's climate will be unusually cold. The Sun is less luminous than usual. There are likely to be an above average number of flares and prominences. The Sun's rotation is slower than average.arrow_forward13 What is the solar wind? (A) The uppermost layer of the Sun, lying just above the corona B A stream of charged particles flowing outward from the surface of the Sun с D The wind that causes huge arcs of gas to rise above the Sun's surface The strong wind that blows sunspots around on the surface of the Sunarrow_forwardThe Sun's photosphere is a. the central region where the Sun originates b. the part of the Sun which the light comes that we see when we look at the Sun with our eyes c. the hottest region of the Sun d. the outermost layers of the Sun's atmosphere e. the first region you would come to when leaving the corearrow_forward
- How long does it take for energy produced in the Sun's core to reach the photosphere? A. a few seconds B. a few hours O C. a few years D. a few hundred years E. a few hundred thousand yearsarrow_forwardWhy do the magnetic fields lines of the sun get warped? a. effects of the solar wind b. surface of the sun is cooler near the poles c. uneven fusion rates in the core d. equator rotates more rapidly than the polesarrow_forwardIt what layer of the sun does fusion occur? a. core b. radiative zone c. corona d. convective zonearrow_forward
- 1. The Sun’s mass is ~2x1030 kg. If 10% of this is Hydrogen available in the core, how long will the Sun be able to continue fusing hydrogen at this rate? This is considered the Sun's "lifetime". If the Sun is 4.6 billion years old (and assuming it's power output is constant), how many years does it have left?arrow_forwardFor several hundred years, astronomers have kept track of the number of solar flares, or sunspots which occur on the surface of the sun. The number of sunspots counted varies periodically from a minimum of about 10 per year to a maximum of about 110 per year. Between the maximum that occurred in the years 1750 and 1948, there were 18 completed cycles. A.) What is the period of the sunspot cycle? B.) Assume that the number of sunspots varies sinusoidally with the year. Sketch a graph of two sun spot cycles, starting in 1948. C.) Write an equation expressing the number of sunspots per year in terms of the year. D.) what is the first year after 2000 in which the number of sunspots will be about 35? A maximum?arrow_forward7 Why do sunspots look dark? they are holes in the photosphere through which the cooler interior of the Sun is visible O they are much cooler than the rest of the surface of the Sun due to changes in the Sun's magnetic field O they are patches of the photosphere that burn up, creating ashes that look dark O Sunspots are regions in the upper chromosphere where there is a lot of coronium, which absorbs light O they are much hotter than the surrounding area, so their emission peaks in UV wavelengths, which our eyes cannot see с C 5 O 0 D "Aarrow_forward
- Step-by-step, explain how energy flows from the center of the Sun to Earth.arrow_forwardSince the rotation period of the Sun can be determined by observing the apparent motions of sunspots, a correction must be made for the orbital motion of Earth. Explain what the correction is and how it arises. Making some sketches may help answer this question.arrow_forwardDescribe the two main ways that energy travels through the Sun.arrow_forward
