Volcanoes

The nature and formation of volcanoes

Volcanoes are openings in Earth's crust allowing molten rock, ash, and gases to escape. They form at tectonic plate boundaries and over mantle plumes.

What do you already know about volcanoes?

Plate tectonics and volcano formation

Plate boundaries: divergent, convergent, transform faults, and hotspots. Volcanoes take various forms.

Types of volcanoes and their features

Shield volcanoes, cinder cones, stratovolcanoes, and their distinct characteristics and eruption styles.

Impacts of volcanic eruptions

Large eruptions can lead to climate changes and historical famines.

Volcanism on other planets

Other planets exhibit volcanic features, indicating similar geologic processes elsewhere in the solar system.

Etymology of the word 'volcano'

The term 'volcano' originates from the Roman god Vulcan.

Study of volcanoes (Volcanology)

The scientific study of volcanoes is known as volcanology.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
