Geology | 02 - Plate Tectonics
From a retired teacher, I congratulate you on your lectures. You are an expert in your field and have the ability and graphic skills to present the subject matter in easily understandable form to ‘novices’. Suffice to say, this is the first comment I have been inspired to write since becoming a ‘You Tube’ fan, and hold your work in admiration. Well done and thank you!
