Types of volcanoes

I can name the key features of volcanoes and explain how composite and shield volcanoes are formed.

These resources will be removed by end of Summer Term 2025.

Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.

These resources were created for remote use during the pandemic and are not designed for classroom teaching.

Lesson details

Key learning points

  1. There are two main types of volcano: composite and shield volcanoes.
  2. Composite volcanoes are usually found at destructive plate boundaries and they are highly explosive volcanoes
  3. Shield volcanoes are usually found at constructive plate boundaries.
  4. Some eruptions are explosive, whereas others are effusive.

Keywords

  • Crust - the outer layer of Earth where our continents and oceans are and is the layer on which we live

  • Magma - molten or semi-molten rock underground

  • Mantle - the layer between Earth’s outer core and crust. It is the largest layer of Earth and is mostly semi-molten lava

  • Destructive plate boundary - a boundary where two tectonic plates move together causing volcanoes and earthquakes

  • Constructive plate boundary - a boundary where two tectonic plates move apart, causing volcanic eruptions and earthquakes

Common misconception

Lava and magma can be used interchangeably.

Magma is molten rock underground, whereas lava is molten rock above Earth's surface.

You can model viscosity by pouring honey and water onto a tray and observing which moves faster. This can be an imagined task without equipment too.

6 Questions

Q1.
What are the layers of Earth in order, from the surface to the centre?
Mantle, crust, core, outer core
Correct answer: Crust, mantle, outer core, inner core
Crust, outer core, mantle, inner core
Mantle, inner core, crust, outer core
Q2.
What is the mantle mostly made of?
Solid rock
Correct answer: Molten rock (magma)
Ice
Metal
Q3.
What is slab pull in tectonic plate movement?
When magma pushes plates apart at mid-ocean ridges
When plates slide past each other without creating or destroying crust
Correct answer: When a sinking plate pulls the rest of the plate into the mantle
When tectonic plates move because of earthquakes
Q4.
What is an earthquake?
A large wave in the ocean
Correct answer: A sudden shaking of Earth's surface
A volcanic eruption
A strong windstorm
Q5.
What happens at a constructive plate boundary?
Correct answer: Plates move apart, forming new crust
Plates push together and form mountains
One plate sinks under another
Plates slide past each other
Q6.
Do tectonic plates float on liquid magma?
Yes, they float on completely liquid rock
Correct answer: No, they move on the solid but slowly flowing mantle
Yes, but only in some places
No, they do not move at all
