When tectonic plates collide, denser plates dive under less dense ones, creating trenches and mountains. New sea floor is constantly created as plates move apart, keeping Earth from shrinking.

A plate boundary is where two tectonic plates meet. There are three types of plate boundaries: convergent, divergent, and transform.

These boundaries result in seafloor spreading, rift valleys, volcanoes, and earthquakes. The process begins with hot magma rising, causing the lithosphere to crack and form rift valleys. Over time, these valleys can fill with water, forming seas. As the land continues to spread, mid-oceanic ridges form, creating an underwater mountain chain.

Divergent boundaries create new crust, while convergent boundaries, where plates collide, can form mountains, island arcs, earthquakes, and volcanoes. The subduction of one plate under another can result in deep trenches and underwater volcanoes.
