Why Continents Are High

The video explains the crucial role of water in Earth's geology, particularly in the formation of continental crust. It highlights how granite, a lightweight igneous rock, forms from magma due to tectonic activity beneath ocean trenches. This process involves water lowering the melting temperature of rocks, leading to the creation of low-density magma that forms granite mountains. Over time, these granite formations contribute to the assembly of continents, illustrating the dynamic nature of Earth's surface.
