Middle Layer Of The Sun- Astronomy

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.
