Final answer:
Animals are often most active just before storms due to their heightened senses. Pets like dogs and cats, sharks, and even rodents can exhibit behaviors that indicate an approaching natural disaster, making it crucial to be watchful of these signs.
Step-by-step explanation:
Many animals are most active just before a storm, and it is important to be especially watchful for their behavior during fair weather periods that precede storms. For example, dogs and cats may exhibit unusual behaviors like howling or becoming restless due to their acute senses, such as a strong sense of smell, which may alert them to upcoming natural disasters. Similarly, sharks have been observed moving to deeper water before hurricanes hit, possibly reacting to changes in air pressure. On the other hand, rodents that live underground tend to flee their habitats in response to signals that might predict earthquakes, such as the Earth's tilting or other subtle changes. Thus, these animals are demonstrating heightened activity that can serve as a natural warning system for impending weather changes.
