Plate boundaries are associated with geological events such as earthquakes and creation of topographic features like the mountains, volcanoes, mid-ocean ridges, and oceanic trenches.
Divergent boundaries are characterized by the movement of tectonic plates away from each other, leading to several geologic events. One of the most common events is volcanic activity, as magma rises to fill the gap created by the separating plates, forming new crust. Earthquakes can also occur along these boundaries due to the stress and friction between the moving plates. Additionally, rift valleys can form as the crust thins and breaks, creating linear depressions in the landscape.
Most earthquakes, volcanoes, and mountain building occur along tectonic plate boundaries. This is because the movement of these plates creates stress and pressure that can lead to these geological events. The Ring of Fire, a horseshoe-shaped area around the Pacific Ocean, is the most active region for these geological activities.
Along continental divergent boundaries, rift valleys or rift zones can form as the continental plates move apart. These rift zones may be accompanied by volcanic activity and seismic events as the crust stretches and thins. Over time, if the divergence continues, a new ocean basin may form as the continents separate further.
Intermediate plate geology refers to tectonic plates that are characterized by a composition and behavior that falls between those of oceanic and continental plates. These plates often feature volcanic activity and seismic events due to their positioning at convergent or divergent boundaries, where they interact with other plate types. They typically comprise both basaltic and granitic materials, resulting in a diverse geological landscape. This intermediate classification helps in understanding the processes of plate tectonics and the formation of various geological features.

Because mass extinction events marked the loss of a number of a species to fill the available ecological niches, these events correspond to geological period boundaries.
At plate boundaries, geological events such as earthquakes, volcanic eruptions, and the formation of mountain ranges can occur. These events happen due to the movement and interaction of tectonic plates along the boundaries, leading to pressure build-up and release in the Earth's crust.
Intraplate activity refers to geological movements that occur within the interior of tectonic plates, away from plate boundaries. This type of activity is different from other tectonic plate movements, such as convergent or divergent boundaries, where plates collide or separate. Intraplate activity can include events like earthquakes, volcanic eruptions, and uplift of land, and is often less frequent and more localized compared to movements at plate boundaries.
Although earthquakes can occur anywhere on the planet with little or no warning, the strongest earthquakes occur near the plate boundaries, as the plates converge (collide), diverge (move away from another)

By geological events.
Geological events and their representation in the geological record.
Scientists determine when one era ends by looking at significant geological, climatic, or biological events that mark a distinct change in the earth's history. These events are usually reflected in the rock record or fossil record and help to establish boundaries between different geological eras.
Earthquakes are most common at transform plate boundaries, as the plates slide past each other, causing friction and stress to build up. These boundaries are also associated with frequent small-scale faulting and occasional tsunamis resulting from underwater earthquakes. Volcanic activity is less common at transform plate boundaries compared to divergent or convergent boundaries.
