Volcanoes and earthquakes word bank for KS2

The KS2 geography statement asks pupils to describe and understand key aspects of physical geography, including volcanoes and earthquakes. Description is the easy half; understanding needs a model of the inside of the Earth. Start with the layers: the thin, hard crust we live on, the hot mantle beneath it, and the core at the centre. A peach or a boiled egg cut in half is the classic model, and pupils can label it with crust, mantle and core from the mat.

Tectonic plates is the hardest topic word, so give it time. The crust is split into huge pieces that move very slowly, a few centimetres a year, about as fast as fingernails grow. Most volcanoes and earthquakes happen where plates meet: where they pull apart, push together or slide past each other. A world map of plate boundaries next to a map of volcanoes and earthquakes lets pupils discover the pattern themselves, including the Ring of Fire around the Pacific Ocean.

The most common mix-up in the topic is magma and lava. They are the same melted rock in different places: magma while it is underground, lava once it comes out of a volcano. A simple sentence pattern fixes it: “When magma erupts, it becomes lava.” Ask pupils to use both words in one sentence every lesson for a week.

Active, dormant and extinct are the second set to get right. An active volcano has erupted recently or is erupting now; a dormant one is asleep for now, but not finished; an extinct one is not expected to erupt again. Arthur’s Seat in Edinburgh is an extinct volcano, which surprises pupils who think the UK has nothing to do with volcanoes. There are no active volcanoes in the UK today.

The word mat is split so pupils can do both jobs the statement asks for. The adjectives (molten, fiery, steaming, glowing, jagged) are for description: a setting paragraph or a poem about an eruption. The verbs (rumble, flow, cool, harden) are for explanation: what happens, in order, when a volcano erupts. An explanation text that uses time connectives and at least four verbs from the mat is a strong KS2 outcome.

Fertile is on the mat for a reason. Pupils often ask why anyone would live near a volcano, and the answer is that volcanic soil is very fertile, so farming there is good. That question leads to a balanced argument, which uses the topic words and shows real understanding.

Real events make the topic memorable, and some are safer starting points than others. The 2010 eruption of Eyjafjallajökull in Iceland sent an ash cloud across Europe and grounded flights for days, which pupils can explore through maps and news reports without distressing detail. Mount Etna in Sicily is one of the most active volcanoes in Europe and is watched closely by scientists. Monitor and predict lead into how volcanologists use seismometers and other instruments to warn people in time.

Pupils’ own stories can take the same calm approach: young scientists on a volcanic island read the signs that a dormant volcano is waking and help the village get ready safely. It is a good model, where the tension comes from reading clues and acting in time.

Earthquakes need their own words: fault, shake and seismometer. A fault is a crack in the crust where rocks move. Pupils can model one with two blocks of wood rubbing past each other under pressure, feeling the sudden jolt when they slip. Scientists measure an earthquake’s strength on a magnitude scale; Year 5 and 6 pupils can compare two earthquakes using the numbers and explain what made one more damaging than the other.
