Filtergrams of the chromosphere reveal ____, which are flame-like structures extending into the lower corona.
A
granules
B
spicules
C
limbs
D
None of the above
Explanation: 

Detailed explanation-1: -Filtergrams of the chromosphere reveal spicules flame-like structures extending upward into the lower corona. The Corona is the Sun’s outermost atmospheric layer and can imaged using a coronagraph. It is composed of very low density, very hot gas extending many solar radii from the visible Sun.

Detailed explanation-2: -The top of the chromosphere, (spica=point) flamelike structures that extend upward about 10, 000 kilometers into the lower corona, almost like trees that reach into our atmosphere. The most conspicuous features on the surface of the Sun are the dark blemishes.

Detailed explanation-3: -The main structural feature of the chromosphere are its spicules. These “spikes” are narrow jets of bright gas which rise up from the photosphere and sink back down on a time scale of roughly 5 to 15 minutes.

Detailed explanation-4: -The chromosphere appears bright red because the hydrogen in the Sun emits a reddish-colored light at high temperatures. The chromosphere is a thin layer of plasma that lies between the Sun’s visible surface (the photosphere) and the corona (the Sun’s upper atmosphere).

Detailed explanation-5: -The corona has been found to emit X-ray radiation (the corona is a plasma; at temperatures greater than a million degrees a plasma will radiate a lot of X-rays).
