Earth’s lithosphere is broken into large slabs called tectonic plates. They float atop the semi-fluid asthenosphere.
Heat from Earth’s core creates convection currents in the mantle, pushing plates slowly across the surface.

Plates meet at boundaries: – Divergent (move apart) – Convergent (collide) – Transform (slide past)
Most earthquakes and volcanoes occur along plate boundaries where stress and magma build up.
Plate collisions form mighty mountains like the Himalayas. Subduction zones create deep ocean trenches.
Plates move a few centimeters each year—shaping continents, oceans, and climates over millions of years.
From earthquakes to shifting continents, plate tectonics tells the story of our planet’s dynamic nature.
