Tectonic plate movement causes several natural phenomena, including earthquakes, volcanic eruptions, and the formation of mountain ranges. When plates collide or slide past each other, they create stress along faults, leading to earthquakes. Volcanic activity occurs when tectonic movements allow molten rock to escape from the Earth's mantle. Additionally, the collision of plates can cause the crust to buckle and fold, forming mountains over millions of years. The movement of these plates is a fundamental process that shapes the Earth's landscape and influences geological activity globally.
