Solar Winds and the Auroras (Zong)
There are many fascinating phenomena that occur because of our sun. One such is solar wind, which causes the southern and northern lights in the respective poles of our earth. Solar wind is a stream of particles, mostly electrons and protons, released from the upper atmosphere of the sun. When this stream reaches the earth, the earth’s magnetic field (known as the magnetosphere) deflects most of the particles away, but some of the particles find their way to the polar cusp, where they are lead to the poles. From there, they collide with the upper atmosphere, sending the electrons into quantum leaps and releasing their energy into visible light. Since the only openings in the earth’s magnetosphere are at the poles, auroras are never seen elsewhere.



Solar Eclipses (Zong)
A solar eclipse is another interesting occurrence associated with the sun. It happens when the moon passes between the sun and the earth, whereby the sun may be partially and or totally obscured when viewing from locations on earth. There are four types of solar eclipses: total solar eclipses, when the sun is completely covered by the sun; partially solar eclipses, when the sun is only partially covered; annular solar eclipses, when the moon appears smaller than the sun, and a bright ring appears around the moon; and hybrid eclipses, a transition between annular and total eclipses. During total eclipses, the only visible parts of the sun are solar flares, and the corona, the halo around the blacked out sun. The corona is the upper atmosphere of the sun and little is known about it, which is why solar eclipses are very important to astronomers, since it isn’t visible in contrast with the rest of the sun. Unfortunately, solar eclipses are exceedingly rare, with only two to five occurring each year. The next one is ecpected to pass through Asia on July 22nd this year.



The Sun's Weather Effects (Guled)
All seasons of the year happen by the earth being tilt. Seasonal change happens for the reason of the earth's orbit around the sun and the earth's tit axis. Most of the Sun's affect on Earth is the weather,since the Earth is tilted different locations in our planet have a different weather forecasts, being closer to the equator means that the air in earth's atmosphere is warmest around the equator (because the sun reaches the earth at a 90 degrees angle). Our Sun has different effects on different weather, when our Sun always heats up our atmosphere, and this is where the weather starts from to create and form our weather in our planet.
