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.
