Sun Review Flashcard

Front

What is the convection zone of the sun?

Back

The convection zone is the outer layer of the sun's interior where hot gas rises, cools as it reaches the surface, and then sinks back down to be reheated.

Front

What is the radiation zone of the sun?

Back

The radiation zone is the layer of the sun where energy is transferred outward by radiation, and it is located between the core and the convection zone.

Front

What are sunspots?

Back

Sunspots are areas on the sun's surface that are cooler than the surrounding areas, appearing darker due to lower temperatures.

Front

What are solar flares?

Back

Solar flares are sudden eruptions of energy on the sun's surface that release gas and energy into space.

Front

What is nuclear fusion?

Back

Nuclear fusion is the process by which the sun generates energy, combining hydrogen atoms to form helium and releasing energy in the process.

Front

What is the core of the sun?

Back

The core is the innermost layer of the sun where nuclear fusion occurs, producing the sun's energy.

Front

What is the corona of the sun?

Back

The corona is the outermost layer of the sun's atmosphere, visible during a solar eclipse, and is much hotter than the surface.

Front

What is the photosphere?

Back

The photosphere is the visible surface of the sun that emits light and is the layer we see from Earth.

Front

What causes solar winds?

Back

Solar winds are streams of charged particles released from the sun's corona, influenced by the sun's magnetic field.

Front

What are prominences?

Back

Prominences are large, bright features extending outward from the sun's surface, often associated with solar flares.
