How have astronomers inferred that the sun rotates?
The sun rotates counter clock wise, and the sunspots help with the rotation of the sun.
What evidence is there that the sun rotates?
One clue is the movement of sunspots on the surface of the Sun. Observations over several days will show the sunspots moving with the rotation of the Sun. The rotation period of the Sun is between 25 and 34 days (depending on latitude).
Are sunspots hotter or colder regions of the sun?
No, sunspots are cooler than the photosphere.
Do sunspots occur on the surface of the sun?
What is true about sunspots
Sunspots are temporary disturbances in the sun's .?
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
What are the two observation that Galileo made?
Galileo looked at the sun and observed dark blemishes on its surface (which are now called sunspots). From the movement of these blemishes, he was able to determine that the sun has a rotation period of about one month.
How the sun moves when the sunspots move from WEST TO EAST?
By the Sun's rotation.
How have astronomers inferred that the sun rotates?
The sun rotates counter clock wise, and the sunspots help with the rotation of the sun.
Idenitify two conclusions Galileo drew from his observation of sun spot dark spot on the sun?
He looked at the sun and observed dark blemishes on its surface, which are now called sunspots. From the movement of these, he was able to determine that the sun has a rotation period of about one month.
Can you determine the rotational axis of the sun by the movement of its sunspots?
Yes.Yes.Yes.Yes.
Identify two conclusions Galileo drew from his observation of sun spots (dark spots) on the sun.?
Galileo looked at the sun and observed dark blemishes on its surface (which are now called sunspots). From the movement of these blemishes, he was able to determine that the sun has a rotation period of about one month.
What did scientists learn about the sun's rotation by studying the sunspots?
this is easy ... i learned it in science class..... OK......they watched the sun and discovered that new sunspots where appearing and they also notices the same ones came back every bit. ;)

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.
Are sunspots hotter or colder regions of the sun?
No, sunspots are cooler than the photosphere.
How do we know the un rotates?
Taking your question as referring to the Sun, its rotation is inferred by measuring the velocity of sunspots on the Sun's surface. Or of other features such as prominences. The Sun's equator has a velocity of about 7 000km/h. At the equator the rotation period is about 28 days. At 16o latitude, the rotation period is about 25.4 days. At the poles, the rotation period is about 34.4 days.
What can you conclude from your observation from sunspots?
Yes. This is called sunspot extrapolation. For the past 400 years, scientists have been observing the sunspot populations. They have found a variety of qualitative (non-numerical) and quantitative (numerical) data and have concluded that the number of sunspots peaks and falls at a cycle of approximately 11 years.
