What do scientists think Causes sunspots?
Astronomers have known for many years that sunspots are "storms" on the sun's surface, and also that solar prominences seen flaring from the sun during an eclipse probably come from sunspots. what they do not know - yet - is why the sunspots occur in farily regular cycles of many, gradually diminishing to few, and then rising again to many. Times of high sunspot activity are usually also times of high Northern Lights activity and radio interference on earth.
During what years was Picasso alive?
1881 - 1973.
What did the British have to gain by ruling South Africa during apartheid?
SA was not ruled by the British during the apartheid era. The country was independent for a number of years during the time.
When will the world end and how?
Depending on when during the 7 year tribulation the rapture of the church happens of which no man knows the day or the hour, after the tribulation Jesus comes to earth and rules the world for a 1000 years. after the rapture it will be at LEAST 1000 years before the earth is consumed by fire. I guarantee the world will NOT end in 2012 the rapture can happen in 2012 in which the saints will be taken up to meet the Lord. The rapture is not the end of the world! The Mayans are off by at least a thousand years.
Is 104 heart beat per minutes normal for a 25 years old?
It depends on if the rate is in the activity conditions its normal but if it is in the conditions of rest you should have a tachicardia
What is the number of years between periods of sunspot activity?
11 years
How many years pass between a year of where there are many sunspots to the next period of lower amounts of sunspots?
Sunspot activity increases and decreases with a frequency of about eleven years from peak to peak, so there are about five and a half years from a period of highest sunspot activity to a period of lowest sunspot activity. The last peak was in 2001, so the next peak is expected in 2012.
Are the number of sunspots on the sun's surface always the same?
No, sunspot activity increases and decreases. Scientists have observed that the level of sunspot activity follows a cycle of about 11 years (11 years from maximum to maximum and 11 years from minimum to minimum).
How often is there an increase in sunspot activity?
every eleven years lol
Every years the suns activity increases?
Every 11 years (or thereabouts, it varies a little) the sun's activity peaks with a sunspot solar maxima.
How many years is the sunspot cycle?
The sunspot cycle is about 11 years in length.
What happens during an economic depression?
During an economic depression threes a lack of economic activity that can last for several years.
What happens during a period of depression in a country?
During an economic depression threes a lack of economic activity that can last for several years.
How would you describe the way sunspot activity changes over the decades and centuries?
We do not yet have a good understanding of the way that sunspot activity changes. We've only been keeping track of sunspots since the early 1600s. In general, sunspot activity increases and decreases in a cycle that is approximately 11 years long. But the cycle isn't particularly stable; for example, the previous cycle, Solar Cycle 23, lasted for closer to 13 years and the current Solar Cycle 24 has been fairly low in activity. This may have long-term significance in our weather here on Earth; twice in the last 4 centuries, we've seen extended periods of very low sunspot activity, and both periods have been associated with unusually cold weather. Some scientists fear that the current sunspot deficit may be a prelude to a new period of cooler-than-normal weather.
What is the average sunspot cycle in years?
11 years
What are sunspot maximums and sunspot minimums?
Sunspot maximum and sunspot minimum are the points in time (roughly 6 years apart) when the sun is producing the most, or the least sunspots. In the past this has been measured both by sunspot area and sunspot count and is directly tied to the solar magnetic cycle.
Sunspot activity and magnetic storms are related how?
There is a direct correlation between sunspot activity and magnetic storms on earth. At the height of the approximately 11-year cycle of sunspot activity, magnetic storms on earth are more intense and are of greater duration. The intensity of some storms requires a few satellites to be put into "sleep mode" to prevent damage. And the effects on things like the power grid are well documented natural phenomenon that is directly linked to sunspot activity.
