The Sun Flashcard

Front

What is a solar flare?

Back

A solar flare is a sudden eruption of energy on the sun's surface, releasing a large amount of energy and radiation.

Front

What is the photosphere?

Back

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

Front

What is the chromosphere?

Back

The chromosphere is a layer of the sun's atmosphere located above the photosphere, characterized by a reddish glow during solar eclipses.

Front

What is the radiative zone?

Back

The radiative zone is a layer of the sun where energy is transferred outward by radiation, located between the core and the convective zone.

Front

What is the convective zone?

Back

The convective zone is the outer layer of the sun's interior where energy is transferred by convection currents.

Front

What are sunspots?

Back

Sunspots are temporary phenomena on the sun's photosphere that appear as spots darker than the surrounding areas, caused by magnetic activity.

Front

What is solar wind?

Back

Solar wind is a stream of charged particles released from the sun's atmosphere, primarily electrons and protons.

Front

What is a prominence?

Back

A prominence is a large, bright feature extending outward from the sun's surface, often in a loop shape, associated with solar magnetic activity.

Front

How does a solar flare differ from a solar wind?

Back

A solar flare is a sudden burst of energy, while solar wind is a continuous flow of charged particles from the sun.

Front

What role do sunspots play in solar activity?

Back

Sunspots are indicators of solar activity; their number and size can affect solar radiation and space weather.
