Star Science

Which of these statements is NOT true about sunspots?

• Sunspots are not permanent and they can move slowly across the surface of Sun changing size as they move.

• Sunspots are cooler than other parts of the Sun's surface.

• Sunspots are brighter than the surrounding areas of the Sun.

• Sunspots often appear in pairs, and when they connect, solar flares occur.

Whch group of stars includes stars that are very hot, small, and not very bright?

• white dwarfs

• main sequence stars

• giants

• supergiants

What is a fast-moving stream of particles thrown into space by the Sun's solar flares? On Earth, we are protcted by them by Earth's magnetic field, but we perceive them as aurora borealis (or norther nights).

• magnitude

• corona

• solar flare

• solar wind

Identify the function of the part of the Sun labeled as 1.

• Energy from the core is transefered here, to the radiation zone.

• The sun's atmosphere extends for kilometers here, in the corona.

• Nuclear fusion happens here, in the core.

• Energy from the core is transefered here, to the convection zone.

Identify part 2, where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction.

• corona

• convection zone

• core

• radiation zone

Identify part 4. (This part is the visible surface of the sun and a star's outer shell from which light is radiated.)

• photosphere

• convection zone

• core

• radiation zone

Identify part 5. (This is a star's color is only apparent during eclipses.)

• photosphere

• chromosphere

• core

• radiation zone

Identify part 9.

• sunspot
• solar flare
