DESCRIPTION:

A look at how without volcanoes, there would be no life on Earth.

Although destructive, magma from the planet’s molten core builds land, 

and mineral-rich ash from eruptions fertilises the surface. 

TRANSCRIPT: 

Across the surface of our planet, there are 1,500 active volcanoes. 

This is the most active, Kilauea, in Hawaii. Here magma liquid rock from the

planet’s hot interior bursts out through fractures in the earth’s crust.

And it’s been flowing for months. Nothing can stand in the lava’s way. 

Volcanoes are certainly destructive, but without these powerful underground

forces there would be no breathable atmosphere, no oceans, no land, no life.

We can’t control volcanoes but they are vital for all living things on planet earth. 

QUESTIONS: 

1. Define volcanoes? How many of them are active these days? 

2. What is the most active volcano? Where is it located? 

3. Discuss the importance of volcanoes in our lives.
