east to west
[thank you ?]
Sunspots are not permanent. They are temporary. and they move once every 5 years.
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.
By the Sun's rotation.
Sunspots are known to be magnetic phenomena because they are areas on the Sun's surface where the magnetic field is significantly stronger than in surrounding regions. This causes a suppression of convection, leading to cooler temperatures and darker spots on the solar surface. Sunspots often appear in pairs, with one spot having a magnetic field oriented in one direction and the other in the opposite direction.
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.
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).
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.
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.
In what direction did the tropical cyclone move?
To move in a backward motion or direction is to move in the opposite direction as usual, such as walking, running, or driving in reverse.
Convection currents move in upward direction
