Core
What is the core of the sun?
It's where nuclear fusion happens
What is the radiative zone located in the sun?
Just outside the core
Where is the convective zone located in the sun?
Between the radiative zone and the surface
Where is the photosphere located in the sun?
It's the sun's visible surface
What is the atmosphere made of?
The atmosphere is made of gases.
How big is the core compared to the rest of the sun?
The core makes up about 20-25% of the sun's radius
How thick is the radiative zone?
About 300,000 kilometers thick
What happens to energy when it reaches the convective zone?
It moves by convection
What is the photosphere made of?
Hydrogen and helium
how thick is the atmosphere?
The atmosphere is about 300 miles thick.
Why is the core important for the sun's energy production?
The core is crucial because it's where nuclear fusion happens, producing the energy that powers the sun
What is the main method of energy transfer in the radiative zone?
Radiation
What is the main method of energy transfer in the convective zone?
Convection
What color is the photosphere when viewed from the Earth?
Appears yellow
What is the main purpose of the atmosphere?
The main purpose of the atmosphere is to protect life on earth.
What elements are found in the sun's core?
The core mainly contains hydrogen and helium
What elements are found in the radiative zone?
Mostly hydrogen and helium
How does the temperature of the convective zone compare to the radiative zone?
Cooler than the radiative zone
How thick is the photosphere?
About 500 kilometers thick
What happens to air pressure as you go higher in the atmosphere?
Air pressure decreases as you go higher in the atmosphere.
How does the core's temperature compare it the rest of the sun?
The core is the hottest part of the sun, with temperatures around 15 million degrees Celsius
How does the radiative zone compare in size to the core?
The radiative zone is much larger than the core
What causes the convective currents in the convective zone?
Hot plasma rises, cool plasma sinks
What is the primary type of radiation emitted by the photosphere
Visible light
Can you name one layer of the atmosphere?
One layer of the atmosphere is the troposphere
