1 Layers of the Earth 1 2 3 4 1 Crust: thin and solid; thicker under continents than under oceans. 2 Mantle: the thickest layer; mostly solid rock that flows very slowly. 3 Outer core: liquid iron and nickel. 4 Inner core: solid iron and nickel. Not to scale: the crust is drawn thicker. 2 Inside a composite volcano ash cloud main vent magma chamber crater secondary (side) vent layers of ash and lava 3 Plate boundaries: where two plates meet oceanic continental Convergent destructive Plates move towards each other. The denser oceanic plate sinks under the other (subduction) and magma rises. BRINGS composite volcanoes, earthquakes E.G. Mount St Helens, USA magma rises Divergent constructive Plates move apart. Magma rises to fill the gap, then cools and hardens to make new crust. BRINGS shield volcanoes, ocean ridges E.G. Iceland (Mid-Atlantic Ridge) seen from above Conservative or transform Plates slide past each other. No magma rises, so no volcanoes. Plates stick, then slip suddenly. BRINGS earthquakes, but no volcanoes E.G. San Andreas Fault, USA 4 Key vocabulary crust the thin, solid outer layer of the Earth. mantle the thickest layer: mostly solid rock that flows very slowly. tectonic plate a huge, slowly moving slab of crust and upper mantle. magma molten (melted) rock below the Earth's surface. plate boundary the place where two tectonic plates meet. convergent (destructive) plates move towards each other. divergent (constructive) plates move apart; magma fills the gap. conservative plates slide past each other; crust is not made or destroyed. lava molten rock that has reached the Earth's surface. composite volcano steep; layers of ash and thick (viscous) lava; explosive. shield volcano gentle slopes, runny (low-viscosity) lava, gentle eruptions. pyroclastic flow a fast-moving current of hot gas, ash and rock fragments that rushes down the side of a volcano. 5 Key facts 6 Famous eruptions Topic knowledge organiser · Geography · Volcanoes and plate tectonics GEOGRAPHY AGES 11 TO 14 KNOWLEDGE ORGANISER Volcanoes and plate tectonics Most volcanoes and earthquakes are at plate boundaries. Plates move a few centimetres a year, about as fast as your fingernails grow. The core is metal, not lava; the mantle is not a sea of magma. Mauna Loa, Hawaii, is a shield volcano over a hotspot in the middle of a plate. AD 79 Vesuvius, Italy: buried the Roman towns of Pompeii and Herculaneum. 1883 Krakatoa, Indonesia: a huge explosion and deadly tsunamis. 18 May 1980 Mount St Helens, USA: a huge landslide, then a sideways blast. 2010 Eyjafjallajökull, Iceland: its ash cloud disrupted air travel across Europe.

NAME CLASS DATE LEARNING GOAL I can recall and explain the key ideas about plate tectonics and volcanoes. SUCCESS CRITERIA I can define key words such as magma and lava. I can explain the three types of plate boundary. I can label and compare volcanoes. 1 /2 Magma and lava: what is the difference? 2 /1 Name the four layers, from the outside in. 1 2 3 4 3 /2 True or false? "The mantle is a sea of liquid magma." Circle, then correct it. True False 4 /1 How fast do plates move? Give a comparison. 5 /2 Convergent boundary: which plate sinks? Why? 6 /2 Divergent boundary: what happens? Name a place. 7 /2 Conservative boundary: why are there no volcanoes? 8 /2 Give two differences: composite vs shield. 9 /2 What is a pyroclastic flow? Why is it deadly? 10 /2 Number 1 to 4, earliest first. Circle the eruption that disrupted air travel across Europe.

A teaching sequence
Recall and explain vocabulary, Earth structure, plate-boundary processes and differences between composite and shield volcanoes using the organiser as a study aid.
Read the parts of a composite volcano, then compare what happens at different plate boundaries.
Read the complete materialReview diagrams, movement and key terms
Use the labelled Earth layers and composite-volcano diagram to review structure and key terms. Compare convergent, divergent and conservative boundaries by movement and the features the organiser associates with each.
How do the labelled structures and boundary movements connect?
Study examples before covering the organiser
Study the selected eruption examples and vocabulary, then cover the notes.
Which place or term needs a subject-teacher clarification?
Recall definitions, comparisons and labels
Answer the second-page prompts from memory, including definitions, comparisons and diagram labels.
Can you answer without copying from the covered notes?
Check and explain one misconception
Check responses against reviewed notes, correct inaccuracies in another colour and explain one misconception in the pupil’s own words. Ask about any example that needs clarification before discussion.
Which reviewed detail supports the correction in your own words?
Before you teach
Look for the thinking behind an answer, choose the support your class needs and leave room for an independent response.
What to look for
Ask pupils to distinguish magma from lava, explain how plates move at each boundary and connect a named example to the process. Check volcano labels and historical claims against a trusted course source before using them as assessed facts. Ask pupils to explain their reasoning.
Give a little support
Preteach a small group of key terms with diagrams or physical models. Offer the organiser in sections, read prompts aloud and let pupils answer orally before writing. Pair new vocabulary with labelled pictures.
Take the idea further
Ask pupils to compare two boundary settings using a labelled sketch, or to investigate how a specific eruption affected people and places using a reliable source beyond the organiser. Invite them to distinguish evidence from explanation.
Things to keep in mind
The notes simplify dynamic Earth processes and give selected examples rather than a complete geography course. Check scientific terms, place names, dates and the intended curriculum before use; this resource is not an independently verified answer key.
Keep the idea. Make it yours.

Margin Note
This two-page volcanoes organiser reviews Earth's crust, mantle and cores, labels a composite volcano and contrasts plate boundaries and volcano types. It states that the layer diagram is not to scale and the crust is drawn thicker.
Spare Pencil
The organiser combines vocabulary, labelled diagrams and recall prompts, helping pupils connect Earth's structure to plate processes and volcano form. The scale disclaimer makes clear that the picture is a learning model.
Paperclip Perspective
Cover labels and ask pupils to retrieve each term, then reveal them for checking. Compare the composite-volcano diagram with the stated features of shield volcanoes using the page's vocabulary.
One More Question
The diagrams simplify Earth's structure and volcanic systems. Check definitions against the course material and keep the not-to-scale warning visible when pupils interpret relative size.
