From crust to core
Our planet is built in LAYERS, and this puzzle gathers them. You'll be finding the four main ones — the rocky CRUST we live on, the thick MANTLE below it, and the INNER and OUTER CORE of CORE at the centre, made mostly of IRON and NICKEL.
Because every new puzzle reshuffles the planet, no two Earth's layers word searches are the same. One round a backwards CONVECTION hides in a corner; the next a diagonal EARTHQUAKE shakes across the middle.
A planet on the move
The Earth is anything but still, and the words are here. Floating on the MANTLE are the TECTONIC PLATES, both OCEANIC and continental, meeting at a BOUNDARY or a FAULT where an EARTHQUAKE sends out SEISMIC waves. Deep down, MOLTEN MAGMA churns in slow CONVECTION currents, driven by immense PRESSURE, HEAT and DENSITY — all beneath the solid BEDROCK.
It's a great fit for a science or geography topic on the Earth. Tracking down C-O-N-V-E-C-T-I-O-N turns spelling practice into earth science.
How to play
Drag across a word, or click its first and last letter — both work. Each word you spot locks in with its own colour and ticks off the list, so you always know what's left to find.
