Some Natural Phenomena

What would you do if you were caught in a lightning storm? Or are facing an earthquake?

Several centuries ago, volcanic eruptions destroyed several human settlements. Volcanoes were a powerful and mysterious force. People considered them gods and worshipped them, offering prayers and sacrifice to please them. Using the tools of science, people discovered that volcanic eruption is a natural phenomenon where the earth spurts out scalding hot liquid rock, which flows and burns everything near it. Today, people understand this event and take measures to safeguard themselves.

We study natural phenomena to save our lives as individuals and species. Hence, Class 8 Science Chapter 15: Some Natural Phenomena is not only academically important but also practically useful.
