Admin Why are sun spots darker and cooler?
Sunspots are dark, planet-sized regions that appear on the “surface” of the Sun. Sunspots are “dark” because they are cooler than their surroundings. Sunspots are caused by disturbances in the Sun’s magnetic field welling up to the photosphere, the Sun’s visible “surface”.
How do sunspots form and why are they cooler than normal?
Sunspots are cooler because they’re areas of intense magnetism — so intense that it inhibits the flow of hot gases from the sun’s interior to its surface. At the same time, the hot gases blocked by these sunspots flow into the areas around them, making those areas even hotter and brighter than normal.
Why do sunspots appear dark in pictures of the Sun Group of answer choices?
Why do sunspots appear dark in pictures of the Sun? They are too cold to emit any visible light. They are extremely hot and emit all their radiation as X-rays rather than visible light. They actually are fairly bright, but appear dark against the even brighter background of the surrounding photosphere.
Why do sunspots always come in pairs group of answer choices?
The rotation of the charged solar plasma produces a current. The turbulent motions in the Sun’s interior fragment the loops in the solar magnetic field. Sunspots generally appear in opposite-polarity pairs or in opposite-polarity groups when the magnetic field is fractured.
What is the phase of matter in the Sun?
The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter. As we heat up a solid it becomes liquid. Liquid is the second state of matter.
Why does the Sun have black spots?
Sunspots are areas that appear dark on the surface of the Sun. They appear dark because they are cooler than other parts of the Sun’s surface. This motion creates a lot of activity on the Sun’s surface, called solar activity. Sometimes the Sun’s surface is very active.

Which state of matter is usually the warmest?
If you heat a liquid enough, it will change into the gas phase of matter. That’s the hottest phase of matter.
Is sun solid or liquid?
It is, as all stars are, a hot ball of gas made up mostly of Hydrogen. The Sun is so hot that most of the gas is actually plasma, the fourth state of matter. The first state is a solid and it is the coldest state of matter. As we heat up a solid it becomes liquid.
