Temka [501]2 years ago

The characteristic, shared by sunspots, solar flares, and coronal mass ejections, are :

  • They appear as dark spots on the sun's surface.
  • They tend to occur during active periods of the solar cycle.

What is the solar cycle?

  • The solar cycle, also known as the solar magnetic activity cycle, sunspot cycle, or Schwabe cycle, is a nearly periodic 11-year change in the Sun's activity measured in terms of variations in the number of observed sunspots on the Sun's surface.
  • Over the period of a solar cycle, levels of solar radiation and ejection of solar material, the number and size of sunspots, solar flares, and coronal loops all exhibit a synchronized fluctuation from a period of minimum activity to a period of a maximum activity back to a period of minimum activity.
  • This cycle has been observed for centuries by changes in the Sun's appearance and by terrestrial phenomena such as aurora but was not clearly identified until 1843.
  • Solar activity, driven by both the solar cycle and transient aperiodic processes, governs the environment of interplanetary space by creating space weather and impacting space- and ground-based technologies as well as the Earth's atmosphere and also possibly climate fluctuations on scales of centuries and longer.

Dr. jones is known for his difficult pop quizzes. immediately before he springs a pop quiz on his students, he typically goes to
NISA [10]
The correct answer is a conditioned stimulus.

A conditioned stimulus (CS) refers to a previously neutral stimulus, that when repeatedly paired with an unconditioned stimulus (UCS) elicits the same response as the UCS, even in the absence of the UCS. In this example, the CS is Dr.Jones closing the classroom door, because this stimulus by itself elicits a response of anxiety in students.
