Question 1

What is a volcano?

Accepted Answer

A volcano is a geological formation on the Earth's surface that allows molten rock, ash, and gases to escape from below the surface, often resulting in volcanic eruptions.

Question 2

What are the three main types of volcanoes?

Accepted Answer

The three main types of volcanoes are shield volcanoes, cinder cone volcanoes, and composite volcanoes (also known as stratovolcanoes).

Question 3

What characterises shield volcanoes?

Accepted Answer

Shield volcanoes are characterized by their broad, gently sloping sides and relatively mild eruptions. They are typically formed by the eruption of low-viscosity lava, which flows easily and covers large areas.

Question 4

What are the features of cinder cone volcanoes?

Accepted Answer

Cinder cone volcanoes are small, steep-sided volcanoes that are often composed of loose fragments of volcanic material, such as cinders and ash. They typically have a simple conical shape.

Question 5

How are composite volcanoes formed, and what are their features?

Accepted Answer

Composite volcanoes are formed by alternating eruptions of lava and pyroclastic material. They have a characteristic steep profile, with layers of hardened lava, volcanic ash, and other materials. They can produce explosive eruptions.
