How can you tell they’ve got it: Eruption Types & Volcano Shape?

If they’ve got it, you’ll see things like: Contrast effusive eruptions (gentle lava flows) with explosive eruptions (violent blasts of ash and rock); Explain that eruption type depends on properties of the magma such as thickness and gas content; Connect volcano shape to eruption style: shield volcanoes from runny lava, steep cones from thick explosive magma. Or just try it together: If your child compared pictures of a gently oozing Hawaiian volcano and a violently erupting one like Mount St Helens, could they explain why eruptions look so different and how that relates to the volcano's shape?

Eruption Types & Volcano Shape

Your child knows eruptions differ. Runny lava flows gently and builds a wide, low volcano. Thick, gassy magma explodes and builds a steep cone.

In curriculum terms

Understand that not all volcanic eruptions are the same: some flow gently (effusive) and some explode violently (explosive), depending on the properties of the magma, and that volcano shape is related to eruption type
