What do solar flares cause on earth?

Solar flares produce high energy particles and radiation that are dangerous to living organisms.

However, at the surface of the Earth we are well protected from the effects of solar flares and other solar activity by the Earth's magnetic field and atmosphere.

How often do solar flares hit Earth?

A flare occurs when magnetic energy that has built up in the solar atmosphere is suddenly released - mostly in the active regions around sunspots.

Their frequency varies from several a day, when the sun is particularly active, to less than one a week during quiet periods.

What is a solar flare and what are the different types?

'twisted' magnetic fields (usually above sunspots) is suddenly released. ... Solar flares are different to 'coronal mass ejections' (CMEs), which were once thought to be initiated by solar flares.

What does the solar wind help create?

The fast solar wind originates from coronal holes, which are funnel-like regions of open field lines in the Sun's magnetic field. ...

The plasma source is small magnetic fields created by convection cells in the solar atmosphere.

The solar wind is a stream of charged particles released from the upper atmosphere of the Sun, called the corona.

This plasma consists of mostly electrons, protons and alpha particles with kinetic energy between 0.5 and 10 keV.

Embedded within the solar-wind plasma is the interplanetary magnetic field...................

The solar wind varies in density, temperature and speed over time and over solar latitude and longitude.

Its particles can escape the Sun's gravity because of their high energy resulting from the high temperature of the corona,

which in turn is a result of the coronal magnetic field.

At a distance of more than a few solar radii from the Sun,

the solar wind is supersonic and reaches speeds of 250 to 750 kilometers per second.....

The flow of the solar wind is no longer supersonic at the termination shock.

The Voyager 2 spacecraft crossed the shock more than five times between 30 August and 10 December 2007.

Voyager 2 crossed the shock about a billion kilometers closer to the Sun than the 13.5-billion-kilometer distance where Voyager 1 came upon the termination shock......

The spacecraft moved outward through the termination shock into the heliosheath and onward toward the interstellar medium.
