sunspot: A spot or patch appearing from time to time on the sun's surface, appearing dark by contrast with its surrounding
They appear because of strong magnetic forces on the sun. Our magnetic forces are changing on earth too.

How do sunspots change over time?
The number of sunspots increases then decreases in a fairly regular cycle, although it's not totally reliable. The time between each maximum or minimum is usually 11 years. I'm not sure if you mean how do individual spots change, but I've just given this answer about groups of sunspots.
Why do number of sunspots change over time?
because it uses up more of its gases so it cools down more
What does a large number of sunspots mean?
A large number of sunspots indicates a high solar activity, which occurs on an 11-year cycle. Electronic communications can seriously be disrupted during this time.
What evidence is there that the sun rotates?
One clue is the movement of sunspots on the surface of the Sun. Observations over several days will show the sunspots moving with the rotation of the Sun. The rotation period of the Sun is between 25 and 34 days (depending on latitude).
How do you describe the sunspots cycle?
Over a span of about 11 years, the face of the Sun changes. At the low point of the cycle, the Sun may have no sunspots (dark, somewhat cooler areas on the surface of the Sun) or a few sunspots. As the cycle progresses, more sunspots, and larger more active sunspots will appear, until the "Solar Max" at which time the Sun has many, sometimes dozens of spots. The Sun is likely to be more active with more and stronger solar flares. Then the Sun begins to quiet down, and back to being "blank". The whole cycle generally takes about 11 years, but it can be as little as 9 or as long as 13 years. There have been speculations that the sunspot cycle may be associated with changes in the climate, that when sunspots are abundant, the weather is a bit warmer, and that when sunspots are rare, the climate is cooler. The extremes of this phenomenon so far have been two extended periods (70 and 40 years) with almost no sunspots at all. From 1645 to 1715 (back at the dawn of sunspot observation) astronomers observed very few sunspots. In the 1880's, two astronomers named Maunder correlated the period of very few sunspots with a period of unusually cold weather, and later scientists named this period the Maunder Minimum. A later period of very low sunspot numbers called the Dalton Minimum (1790-1830) is correlated with unusually cold weather as well. We're not sure what the connection is between cool weather and low sunspot numbers, or even if this is really a "connection"; "Once is happenstance, twice is coincidence, three times is enemy action", goes the old saying. There has not yet been a third period of low sunspots AND cold weather to correllate.

How does the number of sunspots change over time?
The number of sunspots on the sun varies over a period of 10 or 11 years. Some scientists have hypothesized that short-term changes in climate on Earth may be related to sunspot cycles. Satellites have recently collected data that show that the amount of energy the sun produces changes slightly from year to year. Some scientists think that these increases and decreases, which may be linked to the number of sunspots, may cause changes in Earth's temperature.
Why does the amount of rock change over time?
Erosion caused by wind and water reduces its mass.
What equation do you use to find the rate of change?
Rate of change = amount of change in some period of time/amount of time for the change

Amount of change of one measurment in a given amount of time?
This is the rate, rate of change, or differential with respect to time.

The ratio of an amount of change is called the?
The answer depends on whether the ratio is in the context of the starting value, or time (over which the change takes place), or some other variable.
Change over time is referred to as?
A change over time is often referred to as a gradual change.
What is law conservation of massmatter?
Conservation of mass. It means that in a closed system, the amount of mass doesn't change over time.
