Why do sunspots move across the face of the sun?
Sunspots appear to move across the face of the sun due to the differential rotation of the sun's surface. The sun's equator rotates faster than its poles, causing sunspots to move in what appears to be an east-west motion. This differential rotation is due to the sun being a gaseous body, with different layers rotating at different speeds.
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.
Are sunspots hotter or colder regions of the sun?
Sunspots are actually cooler regions on the sun's surface compared to their surroundings. They appear darker because they are areas of intense magnetic activity that disrupts the normal flow of heat to the surface.
What is the earth always doing?
The Earth is always rotating on its axis, causing day and night cycles. Additionally, it is constantly orbiting around the sun, leading to seasonal changes.
By observing sunspots Galileo concluded that the sun was what?
was rotating on the circumfrence on deznuts
Is the movement of sunspots caused by the spinning of earth on its axis?
No, sunspots are caused by the Sun's magnetic field becoming twisted and concentrated in certain areas. This magnetic activity on the Sun's surface leads to sunspots, not the spinning of the Earth on its axis.
Can you determine the rotational axis of the sun by the movement of its sunspots?
Yes.Yes.Yes.Yes.
How did scientist find that the sun rotates on its axis?
Watching the sunspots travel across the face of the Sun.
Does sun have a twin?
No the sun does not have a twin. It rotates on its own axis.No, the sun does not have a twin. It is on its own, rotating in its own axis.
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.
Why do sunspots move across the face of the sun?
Sunspots appear to move across the face of the sun due to the differential rotation of the sun's surface.

This differential rotation is due to the sun being a gaseous body, with different layers rotating at different speeds.
The earth spins on its axis and what else?
In addition to rotating on its axis (spinning), our earth also revolves around the sun (orbits).
What observation led to Galileo to the conclusion that the sun rotate?
The observation that led Galileo to conclude that the sun rotated was when he looked through his telescope and noticed that their were sunspots on the sun. He later looked through the telescope once again and couldn't see the sunspots.
Astronomers find that light coming from point A at the edge of the sun has a slightly higher frequency than light from point B at the opposite side What do these measurements tell us about the sun's?
This observation indicates that the Sun is rotating about its axis, causing a Doppler shift in the light's frequency. The difference in frequency between points A and B is due to the Doppler effect, showing that different parts of the Sun are rotating at varying speeds.
How does the earth spin and rotate?
no the earth spins on it's axis while rotating around the sun
