riddle - We are the first inhabitants


We are the ancients, though we still sit among you.


We have many forms, and even more layers


No strangers to pressure, we use it to shine through


We'll hold you up while you kneel for your prayers


We have patience beyond compare



We'll crack and break and never whine


But when we fight, you'll know we're there


Especially if you toe the line




What is our name?



Answer



I think you are the



Tectonic Plates




We are the ancients, though we still sit among you.



Plate tectonics probably started on Earth over 3 billion years ago, currently there are seven recognised plates.



We have many forms, and even more layers



Wikipedia gives an extensive list of plates. Processes like subduction mean the plates occupy several layers of the lithosphere.



No strangers to pressure, we use it to shine through




The plates often move and cause areas of pressure in the Earth's crust. This can be the cause of diamond formation.



We'll hold you up while you kneel for your prayers



We live on top of tectonic plates.



We have patience beyond compare



The plates are very slow moving in general, typically from 0 to 100mm per year.




We'll crack and break and never whine
But when we fight, you'll know we're there



A clashing of plates at a convergent boundary can cause earthquakes.



Especially if you toe the line



Toeing the line means being near a plate boundary.
