Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Solar flares, prominences, coronal holes, and coronal mass ejections are all due to disturbances in ____ on the sun.
A
the convective zone
B
the radiative zone
C
the core
D
magnetic fields
Explanation: 

Detailed explanation-1: -It is caused by cooler temperatures, due to the concentration of magnetic activity in the area. These areas where sunspots and solar flares happen have strong magnetic fields that can merge and release a lot of energy. This energy is in the form of protons and electrons, as well as X-ray and UV photons.

Detailed explanation-2: -The more explosive CMEs generally begin when highly twisted magnetic field structures (flux ropes) contained in the Sun’s lower corona become too stressed and realign into a less tense configuration – a process called magnetic reconnection.

Detailed explanation-3: -The heating from the sudden increases in solar radiation during a solar flare disturbs the global thermosphere circulation, which results in the significant change in the horizontal wind.

Detailed explanation-4: -The prominence plasma flows along a tangled and twisted structure of magnetic fields generated by the sun’s internal dynamo. An erupting prominence occurs when such a structure becomes unstable and bursts outward, releasing the plasma.

Detailed explanation-5: -About solar flares and CME’s Both are born when the sun’s magnetic fields explosively realign, driving energy into space. But a solar flare is a brilliant flash of light. A CME is an immense cloud of magnetized particles hurled into space in a particular direction, sometimes toward Earth.

Detailed explanation-6: -They are caused by twisting, chaotic magnetic fields from within the Sun’s convective zone. These powerful magnetic disturbances produce active regions on the Sun, which can often create solar flares and coronal mass ejections (CMEs).
