Tectonic features are geological structures formed by the movement of the Earth's tectonic plates. These plates float on the semi-fluid layer of the mantle and can interact in various ways, leading to the creation of mountains, valleys, and earthquakes. Common tectonic features include faults, folds, and volcanoes, which result from the stress and strain caused by plate movements. The boundaries where tectonic plates meet are crucial in shaping the Earth's surface. There are three main types of plate boundaries: convergent, where plates collide; divergent, where they move apart; and transform, where they slide past each other. Each type of boundary produces distinct tectonic features and geological activity.
