– What are tectonic plates and what contributes to their movement and in turn, the deadly earthquakes?
In: 4
Tectonic plates are a consequence of a planet that is geologically active.its the main reason why ap lanet’s surface will change over time along with surface Erosion.
specifically for[ Earth](https://www.gsi.ie/en-ie/education/our-planet-earth/Pages/The-Earth-structure.aspx) (the page linked has all sorts of info about the Earth’s structure) these are a result of the Earth having a layer just below the crust in the upper mantle(called the asthenosphere) composed of semi solid magma where the crust drifts over it: this causes these plates to move ever so slowly with the more violent motions and collisions manifesting as “earthquakes”
This 3 minute video on plate tectonics may be of interest, it breaks it down to a simple enough level
Earthquakes happen when the plates rub against each other.
Some have high amounts of friction between plates, so they only move in large jerking movements.
These jerking movements cause the destructive Earthquakes that we experience

As kind of a follow up question, so we have earthquakes because what is below the crust after 4.5 billion years is still not solid. Is the core now so well insulated that it will continue to be not solid till the sun burns out or will a very distant future earth be earthquake free?
