The Sun Structure Flashcard

Front

What takes place in the core of the Sun?

Back

Nuclear fusion occurs in the core of the Sun, where hydrogen atoms combine to form helium, releasing energy.

Front

What is the photosphere?

Back

The photosphere is the visible surface of the Sun that emits radiation into space.

Front

What is the chromosphere?

Back

The chromosphere is the lower part of the Sun's atmosphere, located just above the photosphere.

Front

What is the role of the radiative zone?

Back

The radiative zone transports energy from the core through radiation.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process where two hydrogen atoms bond to form one helium atom, releasing energy.

Front

What is the corona?

Back

The corona is the outermost layer of the Sun's atmosphere, visible during a solar eclipse.

Front

What is the convective zone?

Back

The convective zone is the outer layer of the Sun's interior where energy is transported by convection.

Front

How does energy travel from the core to the surface of the Sun?

Back

Energy travels from the core to the surface of the Sun through the radiative zone and then the convective zone.

Front

What is the temperature of the Sun's core?

Back

The temperature of the Sun's core is approximately 15 million degrees Celsius.

Front

What is the significance of solar flares?

Back

Solar flares are sudden eruptions of energy on the Sun's surface that can affect space weather and communication on Earth.
