Summarise one of the three types of plate boundaries in terms of plate movement and eharacteristics.

At divergent plate boundaries, tectonic plates move away from each other, creating new crust as magma rises from beneath the Earth's surface to fill the gap. This process often leads to the formation of mid-ocean ridges, where underwater volcanoes erupt and create new ocean floor. As the plates separate, seismic activity, including minor earthquakes, can occur, but these boundaries are typically less volatile compared to other types. Divergent boundaries are also crucial for shaping oceanic features. For example, the Mid-Atlantic Ridge is an impressive testament to this phenomenon, where you can see the continuous creation of oceanic crust. Not only does this movement contribute to our planet's seismic activity, but it also leads to unique ecosystems, like hydrothermal vent communities, which thrive in these extreme environments. It's like nature's own construction zone, constantly renewing the Earth’s surface!
