Explore tectonic plates, rock layers, and the water cycle.
🏔️ Convergent Boundary
Two plates move toward each other. When an oceanic plate meets a continental plate, the denser oceanic plate subducts beneath. This creates deep ocean trenches, volcanic arcs, and earthquakes. Example: the Andes Mountains.

💧 The Water Cycle (Hydrological Cycle)
Water continuously moves through the environment: evaporation from oceans and lakes, condensation into clouds, precipitation as rain or snow, and collection in rivers, groundwater, and oceans. Solar energy drives this cycle. Click on any stage to learn more.
