Mountains are a product of the long geological history of the Earth, formed by the compression and collision of tectonic plates. These folded mountain ranges are the result of horizontal compressive stress on the Earth's crust, causing the rock layers to bend and fold. The formation process is called mountain building, which is a geological event that takes millions of years. Common structures include anticlines and synclines, which are upward convex and downward concave bends formed by compression of rock layers. The folded terrain of Australia is a natural wonder under the influence of internal forces on the Earth, which is not only an important clue for geologists to study geological history, but also of great significance for understanding the tectonic movements of the Earth's plates.
