Sun Quiz Flashcards
The core of the sun
A portion of the inner three layers of the sun’s interior and the hottest. Where nuclear fusion takes place.
- 27 million degrees Fahrenheit (15 million degrees Celsius)
The Radiation Zone
A portion of the inner three layers of the sun’s interior.
A region of very tightly packed gas where energy is transferred mainly in the form of electromagnetic radiation
-7,000,000°F (4,000,000°C)
The Convection Zone
A portion of the inner three layers of the sun’s interior.
Hot gases rise from the bottom of this zone and gradually cool as they approach the top of the sun’s surface.
- 4 million degrees F (2 million degrees C).
Nuclear Fusion
The process that happens in the core of the sun, where hydrogen atoms fuse to helium atoms, creating intense amounts of energy and heat.
Photosphere
The inner layer of the sun’s atmosphere. Responsible for giving off visible light.
Chromosphere
A layer of the sun’s atmosphere, where the sun get’s it red glow.
-the color sphere.
Corona
The faintest layer of the sun’s atmosphere which sends out electrically charged particles called solar wind.
Sunspots
Areas of gas on the sun’s surface that are cooler than the gas around them. Usually occur in groups.
it usually consists of two parts: an inner darker core, the umbra, and a surrounding less dark region, the penumbra.
They appear dark only in contrast with the hotter, brighter photosphere around them.
Cycles in intervals of 11 years.
Prominences
Reddish loops of gas that release from the sun;s surface and link different sunspots together.
Solar Flares
Intense energy gathered from preminces loops linking together that suddenly explodes into space. Can greatly increase solar wind.
Solar wind
Electrically charged particles that get released from the sun’s corona and can cause problems to surrounding planets.
Zeeman Effect
the splitting of a spectral line into two or more components of slightly different frequency when the light source is placed in a magnetic field
Coronal Holes
Large dark regions of the corona that are relatively cool and quiet. Release solar energy straight into space. Emits low levels of magnetic fields.
Coronal Mass-Ejections
a massive outburst of solar material from the Sun’s outer atmosphere.
Emits plasma
transition region
the part of the Sun where the rapid temperature rise occurs between the chromosphere and Corona
