What does differential rotation of the Sun cause?
First, the differential rotation of the surface causes the magnetic field lines to get stretched and wrapped around the min- latitude regions of the Sun, becoming more and more concentrated towards the lower latitudes as the solar cycle progress.
What is differential rotation of the Sun quizlet?
No, the sun rotates faster on the equator than on the poles, making it not completely spherical. This is called differential rotation.
What is meant by differential rotation?
In a rotating solid body, regions that are adjacent at one point in time will remain adjacent as the body rotates. This means that points further from the rotation centre will travel at greater speeds than those closer in.
What is differential rotation quizlet?
Differential rotation. The tendency for a gaseous sphere, such as a jovian planet of the Sun, to rotate at a different rate at the equator than at the poles. More generally, a condition where the angular speed varies with location within an object. Great Red Spot.

What is differential rotation astronomy definition?
Differential rotation is seen when different parts of a rotating object move with different angular velocities (rates of rotation) at different latitudes and/or depths of the body and/or in time. This indicates that the object is not solid. In fluid objects, such as accretion disks, this leads to shearing.
How would you describe the Sun’s rotation quizlet?
How does the sun rotate? It rotates faster on it equator then on higher latitudes. The type of rotation is differential rotation, it the rotation of a body in which different parts of the body have different periods of rotation. Solar flares: an explosive release of energy.
Who discovered the differential rotation of the Sun?
Christoph Scheiner (“Rosa Ursine sive solis”, book 4, part 2, 1630) was the first to measure the equatorial rotation rate of the Sun and noticed that the rotation at higher latitudes is slower, so he can be considered the discoverer of solar differential rotation.
Does Earth rotate differential?
The "effective" rotation of Earth thus increases as we move poleward, and thus Earth's atmosphere and ocean are said to be in differential rotation. We take this effect into account by allowing the Coriolis parameter, f, to equal twice the vertical component of the rotation.
What caused by the differential rotation of the sun as equatorial rotation twists the magnetic field?
It rotates on it's axis about once every 27 days. But the equatorial region of the sun rotates faster, while the poles rotate slower. It is this differential rotation that winds up and twists the internal magnetic field into complex loops. These loops emerge above the surface of the sun (the photosphere) as sunspots.
What is the rotation period of the sun quizlet?
These observations indicates that the Sun rotates in about a month, but it does not do so as a solid body. Instead, it spins deferentially — faster at the equator and slower at the poles, like Jupiter and Saturn. The equatorial rotation period is about 25 days.
Why does the Sun display different Synodic rotation periods?
The synodic period is longer because the Sun must rotate for a sidereal period plus an extra amount due to the orbital motion of the Earth around the Sun.
What term explains why the Sun rotates faster at its equator than at its poles?
No the sun rotates faster on the equator than on the poles making it not completely spherical. This is called differential rotation.
What is the rotation period of the Sun?
about 27 days The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots.
What caused by the differential rotation of the Sun as equatorial rotation twists the magnetic field?

It is this differential rotation that winds up and twists the internal magnetic field into complex loops. These loops emerge above the surface of the sun (the photosphere) as sunspots.
What is differential rotation astronomy?
Differential rotation is seen when different parts of a rotating object move with different angular velocities (rates of rotation) at different latitudes and/or depths of the body and/or in time. This indicates that the object is not solid. In fluid objects, such as accretion disks, this leads to shearing.
What is the direction of rotation of the sun?
The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not rotate like a solid. Different sections rotate at different speeds!
What is Sun’s rotation direction?
The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not rotate like a solid. Different sections rotate at different speeds! The Sun actually spins faster at its equator than at its poles.
Is Sun rotate on its axis?
The Sun rotates on its axis once in about 27 days. This rotation was first detected by observing the motion of sunspots. The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
Does the Sun rotates from west to east?
Answer: The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins — toward the east.
Does the Sun rotate clockwise or counterclockwise?
counter-clockwise Answer: Most of the objects in our solar system, including the Sun, planets, and asteroids, all rotate counter-clockwise.
Which direction does the Sun rotate?
counterclockwise The Sun spins or rotates on its axis in the same direction as Earth (counterclockwise, when looking down from the north pole). Because it is a gas, it does not rotate like a solid. Different sections rotate at different speeds! The Sun actually spins faster at its equator than at its poles.
Does the Sun rotate?

The Sun's rotation axis is tilted by about 7.25 degrees from the axis of the Earth's orbit so we see more of the Sun's north pole in September of each year and more of its south pole in March.
In which direction does the Earth revolves around the Sun?
anticlockwise direction The Earth also rotates on its axis in an anticlockwise direction. And the Earth revolves around the Sun in an anticlockwise direction. All the other major planets, and most of the minor planets (asteroids) also orbit the Sun in an anticlockwise direction. (A few comets orbit in the opposite, or clockwise, direction).
Does the Sun rotate from east to west?
The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins — toward the east.
Is Sun stationary or rotating?
Its spin has a tilt of 7.25 degrees with respect to the plane of the planets' orbits. Since the Sun is not solid, different parts rotate at different rates. At the equator, the Sun spins around once about every 25 Earth days, but at its poles, the Sun rotates once on its axis every 36 Earth days.
What is the correct direction of the Earth’s rotation?
west to east Its rotation direction is prograde, or west to east, which appears counterclockwise when viewed from above the North Pole, and it is common to all the planets in our solar system except Venus and Uranus, according to NASA.
Is Sun rotate clockwise or anticlockwise?
counter-clockwise Answer: Most of the objects in our solar system, including the Sun, planets, and asteroids, all rotate counter-clockwise.
How is the rotation of the sun different from the rotation of Earth?
The Sun has a north and south pole, just as the Earth does, and rotates on its axis. However, unlike Earth which rotates at all latitudes every 24 hours, the Sun rotates every 25 days at the equator and takes progressively longer to rotate at higher latitudes, up to 35 days at the poles.
How sun rotates from east to west?
Earth rotation Earth rotates on its axis from west to east, the Moon and the Sun (and all other celestial objects) appear to move from east to west across the sky. The Sun, the Moon, the planets, and the stars all rise in the east and set in the west. And that's because Earth spins toward the east.
