Question

Loop or sheet of glowing gas ejected from an active region on the solar surface, which then moves through the inner parts of the corona under the influence of the sun's magnetic field is called _____________.

a) Coronal mass ejection
b) Solar prominence
c) Solar flare
d) Solar wind

Answer 1

A glowing loop of gas influenced by the sun's magnetic field and ejected from the solar surface into the corona is called a solar prominence.

Step-by-step explanation:

A loop or sheet of glowing gas ejected from an active region on the solar surface that moves through the inner parts of the corona under the influence of the sun's magnetic field is called a solar prominence. These are huge clouds of relatively cool, dense gas suspended in the much hotter corona, and they can be seen against the Sun as features extending beyond the solar limb. The evolution of such solar phenomena can result in a coronal mass ejection (CME), where immense quantities of coronal material, mainly protons and electrons, are ejected into interplanetary space at high speeds.
