What defines a convergent tectonic plate boundary?

A convergent tectonic plate boundary is defined by the interaction where tectonic plates move towards each other, resulting in one plate being forced below another in a process known as subduction. This collision can lead to significant geological activity, including earthquakes, volcanic eruptions, and the formation of mountain ranges.

In the case of convergent boundaries, the impact of the crashing plates can produce intense pressure and heat, often resulting in the recycling of the Earth's crust. This is a fundamental aspect of the plate tectonics theory, highlighting the dynamic nature of the Earth’s surface. Understanding this concept is crucial for recognizing how landforms and geological phenomena are created as a result of plate interactions.
