Uplift, or elevation, refers to the process by which geological forces raise the Earth's surface. This can occur due to tectonic activity, where the movement of the Earth's plates causes land to rise. Uplift can create mountains, plateaus, and other elevated landforms, significantly shaping the landscape. The effects of uplift can be seen in various regions, such as the Himalayas, which were formed by the collision of the Indian and Eurasian tectonic plates. Uplift also influences climate and ecosystems, as higher elevations often experience different weather patterns and biodiversity compared to lower areas.
