Guiding Question

How is the nature of the geologic activity that is observed near a plate boundary related to the type of plate Interaction that occurs at that boundary?

The Earth's outer surface is made up of around 20 tectonic plates, which are massive sections of the Earth's crust that fit together roughly and meet plate boundaries (Coltice et al.,2019). Plate boundaries are important because earthquakes and volcanoes are commonly associated with them. Massive amounts of energy can be released as earthquakes when the Earth's tectonic plates collide. Volcanoes are typically found along plate boundaries because molten rock from deep beneath the Earth, known as magma, may rise upward at these plate crossings.

Claim

The Earth's outer surface has around 20 tectonic plates

Massive energy released when the Earth's tectonic plates grind against one another

Volcanoes are frequently found at plate borders

Different geological features are linked with each of these types of plate borders

As Earth's crust is crushed and forced upward, convergent plate boundaries, like the one between the Indian Plate and the Eurasian Plate

a convergent plate boundary can sometimes result in one tectonic plate sinking beneath another (Kusky, Windley and Polat, 2018).

Plate borders come in a different shapes and sizes. Plate boundaries, for instance, can meet and collide a "convergent", split apart a "divergent", or gliding past each other a "transform" plate border). Different geological features are linked with each of these types of plate borders. As Earth's crust is crushed and forced upward, convergent plate boundaries, like the one between the Indian Plate and the Eurasian Plate, generate towering mountain ranges like the Himalayas. On the other hand, a convergent plate boundary can sometimes result in one tectonic plate sinking beneath another (Kusky, Windley and Polat, 2018). An older, thicker tectonic plate is driven deep into the globe beneath a younger, less thick tectonic plate in a process known as "subduction." A trench">ocean trench can emerge when this process occurs in the ocean. These trenches are among the deepest in the water, and they are frequently the epicenter of powerful earthquakes..
