A common result of tectonic plate movement is the formation of earthquakes and volcanoes. When tectonic plates shift, they can grind against each other, leading to the release of energy in the form of seismic waves, causing an earthquake. This movement can also create cracks in the Earth's crust, allowing magma to rise and result in volcanic activity. The interaction between tectonic plates can also form mountain ranges, ocean trenches, and other geological features, shaping the Earth's landscape over time.
