A sunspot is a dark spot on the sun.The number of sunspots changes in cycles of about 11 years.sometimes there are many, and sometimes there are few.
The most discernable features on the Sun are sunspots; areas that are a little cooler, and therefore a little darker, than the rest of the Sun around them. We know that sunspots are formed by intense magnetic regions, and that large solar flares and prominences are associated with sunspots. There's a cycle of increasing and decreasing numbers of sunspots that runs about 11 years in length, although this can vary by a couple of years. Slower cycles seem to be correlated with fewer sunspots, and faster cycles with more sunspots, but scientists don't have a detailed explanation for why the cycle exists, or why it is 11 years (more or less) in length. We are currently (in 2014) at or near the maximum of the sunspot cycle. You can see the daily view of the Sun and yesterday's sunspot number at the SpaceWeather website, www.spaceweather.com.
Water is a physical feature because it is a natural element that has physical properties such as mass, volume, density, and temperature. It exists in three states of matter (solid, liquid, gas) and can be observed and measured based on its physical characteristics.
At very high temperatures, matter can exist in the form of plasma, which is a hot, ionized gas consisting of positively charged ions and free electrons. This state of matter is often observed in stars, lightning, and nuclear fusion reactions.

Sunspots are dark, cooler spots on the sun caused by the sun's magnetic field. I believe the cycle between highs and lows of sunspot numbers is 11 years.

The correct answer is: Plasmas
I don't think there is. Science can only prove what can be observed.
'Dark matter' and 'dark energy' have not been observed or proven yet.

Catch a Spinarak and Heracross and beat the trainers nothing special exists in pattern bush.
They are equal in magnitude and act in opposite directions.
The most compelling proof that gravity exists is the fact that objects are pulled towards the Earth's center with a consistent force, causing them to fall when dropped. This phenomenon can be observed and measured consistently, providing strong evidence for the existence of gravity.
A law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. It doesn't change. A theory is the explanation but those can and do change.
No, they can't. A scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. These are not like the laws that society impose on people.
