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.

Why do number of sunspots change over time?

because it uses up more of its gases so it cools down more


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.


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 do the number of visible sunspots change over time?

The number of visible sunspots changes over time due to the solar cycle, which lasts approximately 11 years. This cycle involves variations in solar activity, including the magnetic field strength on the Sun’s surface. During the solar maximum, sunspots are more numerous and larger due to increased solar activity, while during the solar minimum, sunspots are sparse. These fluctuations are a result of the complex interactions between the Sun's magnetic field and its plasma.


What is the amount of force applied to an object over a certain amount of time equal to?

The amount of force applied to an object over a certain amount of time is equal to its impulse, which is the product of force and time. Impulse helps to quantify the change in momentum of an object due to the force applied to it over a period of time.


How does a number of sun spots change over time on the sun?

The number of sunspots on the sun varies in an 11-year cycle known as the solar cycle. During the cycle, the number of sunspots increases, peaks, and then decreases. This cycle is driven by the sun's magnetic activity.


How are time and amount related to each other?

Time and amount are related in a way that the longer the time period, the higher the amount can become, assuming a constant rate of change. For example, if an amount grows at a fixed percentage rate over time, the final amount will be larger the longer the time period over which the growth occurs. Conversely, a shorter time period may result in a smaller final amount.


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?

The rate of change is a measure of how one quantity changes over time. It is calculated by finding the difference in the quantity values divided by the difference in time. If the quantity is increasing, the rate of change is positive, while if it is decreasing, the rate of change is negative.


How many sun spots?

The number of sunspots on the Sun varies over an 11-year solar cycle. During periods of high solar activity, there can be hundreds of sunspots visible on the Sun's surface. The next peak in sunspot activity is expected around 2025-2026.
