Here's a breakdown:
* Oceanic Lithosphere:
* Typically ranges from 5 to 100 kilometers thick.
* Younger oceanic lithosphere is thinner, while older oceanic lithosphere is thicker.
* Continental Lithosphere:
* Can be significantly thicker, reaching up to 150-200 kilometers.
* Thicker under ancient continental shields, and thinner under younger mountain ranges.
Therefore, there's no single answer to the question of how thick the lithospheric plate is. It's important to consider the specific location and age of the plate you're interested in.
