Sunspots are not permanent. They are temporary. and they move once every 5 years.
the particles in a liquid slide around and move about smoothly
east to west [thank you ?]
They go and slide past each other:)
Sunspots expand and contract as they move across the surface of the Sun and can be as large as 80,000 kilometers (50,000 mile) in diameter, making the larger ones visible from Earth without the aid of a telescope
they mainly slide on their stomachs and sometimes waddle.
You can move from slide to slide on the left. It contains the slides by clicking navigation.
No, molecules do not expand but they DO move around quicker.
ne heat gives energy for the particles to move around
Coral reefs are immobile, therefore they do not move around. They stay in one spot and expand by creating layers of coral.
By the Sun's rotation.
Particles in a liquid move around and slide past one another. This allows the liquid to flow.
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.
