Sunspots, Solar Winds/Flares

Front

What are sunspots?

Back

Dark spots on the Sun's surface that are cooler than the surrounding areas and are associated with magnetic activity.

Front

How do sunspots affect Earth?

Back

Sunspots are linked to solar winds, which blow particles onto Earth.

Front

What is solar wind?

Back

A continuous stream of charged particles emitted by the Sun.

Front

How much mass does the Sun lose per hour due to solar wind?

Back

5 billion tons.

Front

How often do sunspots appear?

Back

In pairs.

Front

What causes solar flares?

Back

Sudden releases of energy from the Sun's atmosphere due to magnetic field interactions.

Front

What is the temperature of a sunspot compared to the Sun's surface?

Back

Sunspots are cooler, with temperatures around 3,000 to 4,500 degrees Celsius, compared to the Sun's surface temperature of about 5,500 degrees Celsius.

Front

What is the relationship between sunspots and solar activity?

Back

More sunspots indicate higher solar activity, which can lead to increased solar flares and solar wind.

Front

What are the effects of solar wind on Earth?

Back

Solar wind can cause geomagnetic storms, which may disrupt satellites, power grids, and communication systems.

Front

What is a solar flare?

Back

A sudden and intense burst of radiation from the Sun's surface.
