Question

Cyclone and meteor shower are examples of ___________ respectively.

• A. desirable and non-periodic changes
• B. non-desirable and periodic changes
• C. desirable and periodic changes
• D. non-desirable and non-periodic changes

Answer 1

The correct option is D non-desirable and non-periodic changes

Changes that are not useful or that harm us are called non-desirable changes. Cyclone is an example of it, as it causes a lot of damage.
Changes that happen randomly without following any definite time interval are called non-periodic changes. A meteor shower is an example of it, as it occurs randomly.
