Front

What is a sunspot?

Back

A dark area on the Sun’s surface that is cooler than the surrounding areas.

Front

What is solar activity?

Back

Variations in the Sun’s energy output and sudden explosive events on its surface.

Front

What are the three main layers of the Sun's atmosphere?

Back

The three main layers are the photosphere, chromosphere, and corona.

Front

What is the photosphere?

Back

The visible surface of the Sun, where light is emitted.

Front

What is the corona?

Back

The outermost layer of the Sun’s atmosphere, extending millions of kilometers into space.

What causes sunspots?

Back

Sunspots are caused by magnetic activity that inhibits convection.

Front

What is nuclear fusion?

Back

The process by which hydrogen nuclei combine to form helium, releasing energy.
