Question

• where is most of earth’s geological activity concentrated?

Explanation:

Geological activity like earthquakes, volcanic eruptions, and mountain - building is mainly concentrated at the boundaries of Earth's tectonic plates. Tectonic plates are large slabs of the Earth's lithosphere (crust and upper mantle) that move relative to each other. At convergent boundaries, plates collide (e.g., where oceanic plates subduct under continental plates, forming volcanoes and mountain ranges like the Andes). At divergent boundaries, plates move apart (e.g., mid - ocean ridges where new crust is formed). At transform boundaries, plates slide past each other (e.g., the San Andreas Fault, associated with earthquakes).

Answer:

Most of Earth's geological activity is concentrated at the boundaries of tectonic plates (convergent, divergent, and transform plate boundaries).
