What is the best example of a cyclic event? a. the appearance of Halley’s comet every 76 years
b. a hurricane moving up the east coast an hitting Long Island
c. an earthquake near Washington DC
d. a tsunami striking the east coast of Japan

The correct answer is A. The appearance of Halley’s comet every 76 years.

Explanation:

Cyclic events follow a pattern of occurrence, this means they occur every certain time and can be predicted. This category includes natural phenomena such as weather patterns or the phases of the moon. In this context, the one that is an example of a cyclic event is Halley's comet (option A) because the appearance of this comet occurs every certain time (76 years) and this can be predicted, which are two key features of cyclic events. Also, others such as hurricanes, tsunamis, or earthquakes do not follow a precise cycle or cannot be precisely predicted.

c. live where it’s cold and icy
