Middle Layer Of The Sun- Astronomy
This chapter is about Middle Layer Of The Sun- Astronomy
center of the sun
core
joining of hydrogen atoms to form helium
nuclear fusion
A region of the sun with tightly packed gas where enery moves mainly in the form of electromagnetic radiation.
radiation zone
outermost layer of the sun’s interior
convection zone
The sun’s layers, from innermost to outermost, are the core, ____, and convection zone
radiation zone
Inner layer of the sun’s atmosphere. This is considered to be the sun’s surface layer.
photosphere
You see the ___ when you look at an image of the sun.
photosphere
layer of the sun’s atmosphere that has a reddish glow. This is the middle layer of the sun’s atosphere.
chromosphere
Layer of the sun’s atmosphere that looks like a white halo during an eclipse
corona
What is included in the interior layers of the sun?
core,
radiation zone
convection zone
What is included in the atmosphere of the sun?
photosphere,
chromosphere
corona
stream of electrically charged particles from the sun
solar wind
areas of gas on the sun’s surface that are cooler than the areas around them
sun spots
Huge loops of gas that link different parts of sunspot regions are called ___.
prominences
eruptions that occur when the loops in sunspot regions suddenly connect
solar flare
Features on or just above the sun’s surface include…
sunspots
prominences
solar flares
The corona sends out a stream of charged particles called the ___.
solar winds
Why do sunspots look darker than the rest of the sun’s photosphere?
Sunspots are areas of gas on the sun’s surface that are cooler than the gases around them. Cooler gases don’t give off as much light as hotter gases, which is why sunspots look dark.
How is solar wind related to magnetic stomrs on Earth?
Near the north & south poles, electrical particles from the sun can enter the Earth’s atmosphere. There, they create powerful electric currents that caus gas molecules in the atmosphere to glow.
