What are Tectonic Plates?
Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact with one another. These plates float on the semi-fluid asthenosphere beneath them. The movement of tectonic plates is driven by the heat generated from the Earth's core and the gravitational forces.Types of Plate Boundaries
There are three main types of plate boundaries:- Divergent Boundaries: where tectonic plates move away from each other, leading to the formation of new crust. This process often occurs at mid-ocean ridges.
- Convergent Boundaries: where tectonic plates move towards each other, leading to the formation of mountains, deep ocean trenches, and volcanic activity.
- Transform Boundaries: where tectonic plates slide past each other horizontally, leading to earthquakes.
Earthquakes
Earthquakes occur when there is a sudden release of energy along faults in the Earth's crust. This release of energy causes seismic waves that can result in significant ground shaking and damage to structures.Volcanic Activity
Volcanic activity is often associated with convergent and divergent plate boundaries. When tectonic plates move, the pressure and heat generated within the Earth can lead to the formation of magma, which can erupt as lava onto the Earth's surface.Mountain Building
The collision of tectonic plates at convergent boundaries can lead to the uplift and formation of mountain ranges. This process occurs over millions of years as the Earth's crust is folded and faulted.Studying Tectonic Activity
