nibblesI’m a Scientist is like school science lessons meet the X Factor! School students choose which scientist gets a prize of $1000 to communicate their work.
Scientists and students talk on this website. They both break down barriers, have fun and learn. But only the students get to vote.
This zone is the Boron Zone. It has a range of scientists studying all different topics. Who gets the prize? YOU decide!
Good question, this is well outside my area of work… but i seem to remember back to first year geology that they move because they sit/float on the liquid mantle and movement is caused by different thermal zones.

Another good question. What Mark said is basically correct: the tectonic plates sit on top of a liquid mantle, and convection, which is mixing due to regions being at different temperatures, drives their motion. They don’t just move sideways, they also move up and down, and this is what causes mountain ranges to form: one plate sliding under another.
It just so happens that there was an excellent article publish this morning on The Conversation explaining tectonic plates! You can read it here: https://theconversation.edu.au/breaking-new-ground-the-rise-of-plate-tectonics-7514
I think the diagrams presented give a good idea of what’s going on. Please let me know if you need some of the terms in that article explained!
