Volcanoes

Volcanoes

Geological processes of volcano formation

Volcanoes are openings in Earth's crust that allow magma and gases to escape.

What do you already know about volcanoes?

Types of volcanoes and their characteristics

Volcanic types include shield, cinder cone, and stratovolcanoes, each with unique features.

Tectonic plate boundaries and volcanic activity

Volcanoes often form along tectonic plate boundaries due to diverging or converging plates, or at hotspots from mantle plumes.

Effects of volcanic eruptions on climate and societies

Large eruptions can impact climate, causing volcanic winters.

Hotspot volcanism and examples

Hotspots, like the Hawaiian Islands, form as plates move over a stationary heat source.

Features and impacts of supervolcanoes

Supervolcanoes can produce catastrophic eruptions that affect global climates.

Various volcanic features and structures

Submarine and subglacial volcanoes also play roles in shaping Earth's surface and ecosystems.

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.
