How can you use sunspots to tell that the sun is rotating on its axis?
Sunspots can be used to determine the rotation period of the Sun because they appear to move across the Sun's surface as it rotates. By tracking the motion of sunspots over time, scientists can calculate the rotation period of the Sun. This information helps confirm that the Sun is indeed rotating on its axis.
What can you conclude from your observations of sunspots?
Sunspots are temporary dark spots on the sun's surface caused by magnetic activity. Observations of sunspots help track the sun's 11-year solar cycle and provide insight into the sun's magnetic field and its effects on space weather. Changes in the number and size of sunspots can also affect Earth's climate and communication systems.
How have astronomers inferred that the sun rotates?
Astronomers have inferred that the Sun rotates by observing the motion of sunspots across its surface. This phenomenon, known as differential rotation, causes different parts of the Sun to move at different speeds, indicating that the Sun rotates. Additionally, observations of the Doppler shifts in the light emitted by different regions of the Sun also provide evidence of its rotation.
Sunspots are temporary disturbances in the suns what?
Sunspots are temporary disturbances in the sun's photosphere. They appear as black spots because they are significantly cooler areas cause by magnetic activity on the sun. They can be various sizes and move across the sun at various speeds before disappearing.
Who was the first person to believe that the sun did not move across the sky?
the sun dosent move across the sky
What does the way sunspots travel across the face of the sun indicates about the way the sun rotates?
Suspots don't actually MOVE across the face of the Sun; a sunspot pretty much stays put. So when we see sunspots APPEAR to move, what we're actually seeing is the rotation of the Sun itself.
How did scientist find that the sun rotates on its axis?
Watching the sunspots travel across the face of the Sun.

What evidence proves that the sun rotat es on its axis?
We can see sunspots travel across the face of the Sun. Sometimes, for long-lasting sunspots, we can see the same ones 28 days later when they roll around again as the Sun spins.
How the sun moves when the sunspots move from WEST TO EAST?
By the Sun's rotation.
What direction do sunspots move?
Sunspots move across the surface of the sun from east to west as a result of the sun's rotation. This movement is known as the "sidereal motion" of sunspots and takes approximately 13.5 days to complete one full rotation.
Do convection currents carry sunspots across the surface of the sun?
False
What would happen if the sun rotated east to west?
Nothing much. The rising and setting of the Sun appears to happen because the EARTH is rotating, and we don't really notice much about the SUN spinning. It does, of course, and astronomers track sunspots across the face of the Sun as it spins (when there are sunspots, which there mostly haven't been in the last 3 years or so).
What are some things that aren't true about sunspots?
Some misconceptions about sunspots include that they are cooler than their surroundings (in reality, they are about 1,500 degrees Celsius cooler), that they do not emit light (they still emit energy), and that they have a short lifespan (some sunspots can last for weeks or even months).
