Lecture 1 & 2: ater mid-ocean :computer reconstrucion of pangea by edward bullard(1965, main concept to know: Coninental drit-old idea, made in 1910, coninents move around. His idea was rubished by most people because he didn"t come up with a mechanism. Therefore his idea languished which is very common in science. In the 1960s is the ime when we began to explore planet earth. Oceans cover 70% of the planet therefore geology is out of site, out of mind because you cant see it. Key concept in the 60s was the development and applicaion of geophysics. Geophysics- the ability to map remotely whats underneath the oceans, whats underground usually using electromagneic waves(sound waves). These waves go down through water, down through rocks and they bounce back. Ex- you plucking the guitar and you hearing the sound and relecing back from the walls. You can use this informaion in geology to idenify what the structure is at depth.
