What is the claim about the Sun's composition?
The Sun is mainly composed of Hydrogen and Helium.
The Sun is primarily made of Carbon and Oxygen.
The Sun consists mostly of Iron and Nickel.
The Sun is largely composed of Methane and Ammonia.
How much energy does the Sun release per second?
1.21 x 10²⁹ Mega Electron Volts
2.41 x 10³⁰ Mega Electron Volts
3.50 x 10²⁸ Mega Electron Volts
4.00 x 10³¹ Mega Electron Volts
Which elements does the Sun's spectrum match?

What is the goal of understanding the Sun's energy supply?
To understand how the Sun provides a constant, long-lasting energy supply.
To learn about the Sun's surface temperature variations.
To explore the Sun's impact on Earth's climate.
To investigate the Sun's role in solar system formation.
What will happen to the Sun in the future?
The Sun will explode in a supernova within the next century.
The Sun will eventually run out of hydrogen fuel, but it will last for billions of years more.
The Sun will transform into a black hole immediately after it runs out of fuel.
The Sun will remain unchanged for the next million years.
Why is nuclear fusion the source of the Sun's energy?
Nuclear fusion releases much more energy for much longer compared to chemical reactions.
Nuclear fusion is a process that occurs only in stars and not in any other celestial bodies.
Nuclear fusion produces less energy than chemical reactions but is more sustainable.
Nuclear fusion requires extremely low temperatures to occur effectively.
What happens during nuclear fusion in the Sun?
Hydrogen atoms fuse to form Helium.
Helium atoms split to form Hydrogen.
Carbon atoms combine to create Oxygen.
Neutrons are released to form energy.
What happens to light when it passes through gases?
The gases produce black lines, known as absorption or emission lines.
The light is completely absorbed and does not pass through.
The light is reflected back without any change.
The gases emit a bright white light.
What does a spectrometer do?
It measures the temperature of objects.
It separates light into its component colors (spectrum).
It amplifies sound waves.
It captures images of distant galaxies.
What evidence do absorption spectra provide about the Sun?
Absorption spectra patterns are evidence of the elements that make up the Sun.
Absorption spectra indicate the temperature of the Sun's surface.
Absorption spectra show the distance of the Sun from Earth.
Absorption spectra reveal the Sun's age and formation history.
