MCQ - 88-11455

According to the controversial sunspot theory, great storms on the surface of the sun hurl streams of solar particles into the atmosphere, causing a shift in the weather on earth.
A typical sunspot consists of a dark central umbra surrounded by a lighter penumbra of light and dark threads extending out from the center like the spokes of a wheel. Actually, the sunspots are cooler than the rest of the photosphere, which may account for their color. Typically, the temperature in a sunspot umbra is about 4000 K, whereas the temperature in a penumbra registers 5500K, and the granules outside the spot are 6000 K.
Sunspots range in size from tiny granules to complex structures with areas stretching for billions of square miles. About 5 percent of the spots are large enough so that they can be seen without instruments; consequently, observations of sunspots have been recorded for several thousand years.
Sunspots have been observed in arrangements of one to more than one hundred spots, but they tend to occur in pairs. There is also a marked tendency for the two spots of a pair to have opposite magnetic polarities. Furthermore, the strength of the magnetic field associated with any given sunspot is closely related to the spot’s size.
Although there is no theory that completely explains the nature and function of sunspots, several models attempt to relate the phenomenon to magnetic fields along the lines of longitude from the north and south poles of the sun.

Question:

Solar particles are hurled into space by

  1. Undetermined causes
  2. Disturbances of wind
  3. Small rivers on the surface of the sun
  4. Disturbances of wind

Correct Answer: B

Explanation:

“… great storms on the surface of the sun hurl streams of solar particles into the atmosphere.” Storms refer to disturbances of wind. Choice (A) contradicts the fact that great storms have been identified as the cause of particles being hurled into space. In choice (C), there are storms, not rivers on the surface of the sun. Choice (D) refers to what happens as a result of the particles being hurled into space.
