Great Rift Valley

The Great Rift Valley is a long, steep-sided depression in the Earth's surface that stretches from Lebanon in the Middle East down through eastern Africa. It forms because Earth's crust is slowly pulling apart, creating a series of cracks and valleys. This geological activity has shaped impressive landscapes, filled with lakes, volcanoes, and unique ecosystems. The valley is also significant for human evolution, as many ancient fossils and archaeological sites, including early human ancestors, have been discovered there. Overall, it’s a major feature resulting from the planet's dynamic tectonic processes.
