What is the sunspot cycle quizlet?

solar cycle. Also called the sunspot cycle. An 11-year cycle during which the number of sunspots rises to a maximum or falls to a minimum. The periodic change in the number of sunspots; the cycle is taken as the interval between successive minima and is about 11.1 years.

Which of the following is the best answer to the question why does the Sun shine Which of the following is the best answer to the question why does the Sun shine?

Which of the following is the best answer to the question, “Why does the Sun shine?” As the Sun was forming, gravitational contraction increased the Sun’s temperature until the core become hot enough for nuclear fusion, which ever since has generated the heat that makes the Sun shine.

What are sunspots and how do they affect us?

Sunspots are storms on the sun’s surface that are marked by intense magnetic activity and play host to solar flares and hot gassy ejections from the sun’s corona. … It emanates from the sun and influences galactic rays that may in turn affect atmospheric phenomena on Earth, such as cloud cover.

How are sunspots and solar flares similar and different?

Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. Solar flares are a sudden explosion of energy caused by tangling, crossing or reorganizing of magnetic field lines near sunspots.

How does sunspot activity affect Earth?

If sunspots are active, more solar flares will result creating an increase in geomagnetic storm activity for Earth. Therefore during sunspot maximums, the Earth will see an increase in the Northern and Southern Lights and a possible disruption in radio transmissions and power grids.

Why is it important to keep track of the sunspot cycle?

Gases rising from the sun’s hot interior. Why is it important to keep track of a sunspot cycle? The sun is most active durning the years of sunspot maximums, pouring the greatest amount of energy and radiation into the Earth’s environment.

How does the solar cycle affect Earth?

The Sun’s irradiance has its greatest effect on Earth’s upper atmosphere, while the lower atmosphere insulates Earth from the increased heat. If the Sun were driving Earth’s warming, one would expect to see that upper atmosphere getting increasingly hot.

What is meant by sunspot cycle?

Definition of sunspot cycle

: the time between maxima in the varying numbers of sunspots averaging about 11 years but sometimes being many years shorter or longer.

Why does the Sun have a sunspot cycle quizlet?

convection combined with the rotation pattern of the Sun-faster at the equator than at the poles-causes solar activity because these gas motions stretch and twist the Sun’s magnetic field. … the sunspot cycle, or the variation in the number of sunspots on the Sun’s surface, has an average period of 11 years.

What are sunspots and what is a sunspot cycle?

The 11-year sunspot cycle is actually half of a longer, 22-year cycle of solar activity. Each time the sunspot count rises and falls, the magnetic field of the Sun associated with sunspots reverses polarity; the orientation of magnetic fields in the Sun’s northern and southern hemispheres switch.

Will the Sun last forever?

The Sun is about 4.6 billion years old – gauged on the age of other objects in the Solar System that formed around the same time. Based on observations of other stars, astronomers predict it will reach the end of its life in about another 10 billion years.

What causes the cycle of solar activity quizlet?

What causes the cycle of solar activity? Changes in the organization of the Sun’s magnetic field. … The time between eclipses and the average distance between the stars is needed.

What causes the cycle of solar activity?

What causes the cycle of solar activity? … Changes in the organization of the Sun’s magnetic field. How does the number of neutrinos passing through your body at night compare with the number passing through your body during the day? about the same.

What is the importance of sunspots?

Its light provides energy for photosynthesis in plants and algae, the basis for the food chain, which ultimately feeds almost all life on earth. Sunspots also have an indirect but significant impact on life here on earth.

How do sunspots impact global warming?

Sunspots have been observed continuously since 1609, although their cyclical variation was not noticed until much later. At the peak of the cycle, about 0.1% more Solar energy reaches the Earth, which can increase global average temperatures by 0.05-0.1℃.

What is solar wind and how can it affect the Earth?

She explains in more detail how the solar wind disrupts our magnetosphere: “As the wind flows toward Earth, it carries with it the Sun’s magnetic field. It moves very fast, then smacks right into Earth’s magnetic field. The blow causes a shock to our magnetic protection, which can result in turbulence.”

How does the sunspot cycle have an effect on the aurora borealis?

The sun has a heartbeat. Every 10 or 12 years it beats, and it beats hard. This is known as the solar cycle and is measured by the number of sunspots visible on the sun. The more sunspots, the more solar flare energy is being released into space which means more aurora activity!

How do sunspots and solar flares form?

Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere, the Sun’s visible “surface”. The powerful magnetic fields in the vicinity of sunspots produce active regions on the Sun, which in turn frequently spawn disturbances such as solar flares and coronal mass ejections (CMEs).

What are sunspots What is the relationship between sunspots and the energy released by the sun?

There is, for example, a relationship between sunspots and radiation emitted. A sunspot is a dark spot on the surface of the sun. The more sunspots present on the surface of the sun, the more energy the sun gives off. The number of sunspots rises and falls in cycles that last about 11 years.

How does activity on the Sun affect natural phenomena on Earth?

The solar activity cycle can generate solar storms from coronal mass ejections, which are violent and hard to predict. … How does activity on the Sun affect natural phenomena on Earth? Solar activity can affect the aurora, weather, and climate.

How does the Sun provide energy for Earth?

The sun generates energy from a process called nuclear fusion. … The radiant energy travels to the Earth at a speed of 186,000 miles per second, the speed of light. Only a small portion of the energy radiated by the sun into space strikes the Earth, one part in two billion. Yet this amount of energy is enormous.

How can sunspots help determine the period of rotation of the sun?

Each sunspot must travel a distance equal to the Sun’s circumference in order to make a full rotation around the Sun. As observed from Earth, the rotation period, or the time it takes a sunspot to go around the Sun once, is give by the Sun’s circumference divided by the rotation speed.

How are sunspots tracked?

Surveying sunspots with daily hand-drawn drawings is the most basic of ways we study how solar activity rises and falls over time, and it’s the basis of how we track the solar cycle.

Why are sunspots seen moving across the surface of the sun from time to time?

Because sunspots are cooler than the rest of the sun’s surface, they look darker. … To an observer on Earth, sunspots appear to move because sun’s surface itself is moving (though not in one piece, as we discussed).

How does solar activity affect Earth quizlet?

How can solar flares affect Earth? They emit large amount of X-rays and ultraviolet radiation that travel to Earth and increase the ionization of Earth’s upper atmosphere. Flares also emit large amounts of charged particles that are caught by Earth’s magnetic field.

Where are we in the sunspot cycle?

Wolf’s own calculation of the 1755 to 1766 sunspot cycle was labeled as the first, and each sunspot cycle since then has been progressively numbered as such. We are now in Cycle 25.

What is a sunspot and how often do they occur?

Sunspots are formed continuously as the Sun’s magnetic field actively moves through the Sun. The sunspots have lifetimes of days or perhaps one week or a few weeks.

Where do sunspots occur on the Sun?

Sunspots are darker, cooler areas on the surface of the sun in a region called the photosphere. The photosphere has a temperature of 5,800 degrees Kelvin.

Where do sunspots start showing up at the beginning of the sunspot cycle?

mid-latitudes At the beginning of the cycle, sunspots form in the sun’s mid-latitudes. But as the cycle progresses, they occur closer to the equator.

What is the sunspot cycle Why is it sometimes described as an 11 year cycle and sometimes as a 22 year cycle are there longer term changes in solar activity?

The sun’s 11 year cycle is a symptom of a longer 22 year cycle called the solar cycle, or Hale Cycle, which affects the sun’s magnetic fields. Every 11 years, the sun’s poles flip. North becomes south and south becomes north. So every 22 years, the poles return to the position where they started the cycle.

What is the relationship between Earth’s temperature and the number of sunspots that occur quizlet?

What is the relationship between Earth’s temperature and the number of sunspots that occur? An increased number of sunspots causes an increase in Earth’s temperature.
