Question

Ionosphere as a whole is
A. +vely charged
B. -vely charged
C. electrically neutral
D. cannot say

Answer 1

Hint:The above problem can be resolved using the concepts of electrical neutrality of the region consists of the composition of the charged ions. Moreover, it is well known that the name Ionosphere is given in accordance with the data regarding the ionic composition in the ionosphere. The ionosphere contains some amount of free electrons in its atmosphere, and these free electrons carry some magnitude of a negative charge, which on neutralisation with the positively charged cations forms a neutral atmosphere.

Complete step by step answer:
We know that the ionosphere is one of the layers that is maintained on the atmospheric surface of the earth, and it is the most active part of the atmospheric layers. The major composition of the ionosphere includes some random electrons along with positively charged species. These positively charged species are known as anions, and these cations get interacted with the electrons, which are negatively charged. And being negatively charged, the electrons neutralize the positively charged ions to make the ionosphere as a whole as neutral.
Therefore, the ionosphere as a whole is electrically neutral, and option (C) is correct.

Note:To resolve the given problem, one must go through the data regarding the composition of the Ionosphere. Moreover, the knowledge of the atmospheric layers is also necessary for consideration of the elements of the Ionosphere. The term electronic neutralisation is to be remembered while applying the concepts of the Ionosphere.
