A tectonic plate boundary in the Earth's crust can be the location of a new landform.
When tectonic plates move against each other, they can create a variety of landforms, such as mountains, valleys, and volcanic islands. This process is known as plate tectonics and it is responsible for shaping the Earth's surface over millions of years. For example, the Himalayas were formed by the collision of the Indian and Eurasian plates, and the Hawaiian Islands were formed by volcanic activity at a hotspot on the Pacific Plate.
