Ice Age(s) El Nino Greenhouse Effect

U4(c): The Changing Environment – “4 Sphere Interactions” U4: The Changing Environment – Lithosphere/Hydrosphere/Atmosphere Once above the surface of the sea the liquid rock (magma) continues to rise; cooling & forming mountains and plateaus. As mountains and plateaus extend upwards into the atmosphere – they interact with the atmosphere creating “weather” . Ironically, these mountains & plateau land features are now exposed to the very same weather-storm patterns the y have created by their interference with the atmosphere . Tectonic Plates Liquid-rock (magma) pushes upwards until it breaks the sea’s surface. Weathering Erosion Ice Age(s) El Nino Greenhouse Effect Sea-floor “spreading”
