Friendly educational infographic, horizontal 4:3, explaining how earthquakes happen in four clean modules with short readable labels only: tectonic plates, pressure builds, plates slip, seismic waves spread. A cross-section of the earth shows two large rock plates meeting at a fault line, with simple arrows showing slow movement and stored pressure, small houses and trees on the surface for scale, and curved wave lines radiating from the slip point. Warm cream background, teal, amber, and terracotta color blocks, rounded icons, generous white space, clear hierarchy, accurate simple science, no long paragraphs, no logos, no watermark.
