goodness, where was I during school geology lessons!? thankful for your informative presentation! googled a few terms and rewatched multiple times, loads of good notes for an art project - thank you!!!
So, was there a time, long before Pangea, when earth's surface was largely granite floating on magma? Would love to have seen that crystallization as it occurred!
It depends on depth, location and tectonic activity over geologic time. Granite forms slowly generally over 100,000-millions or billions of years depending on the situation
So if it takes so long to become hard, why dont ee think the Egyptians had a softer form of it to build with? It was at least 3000 years softer if that means anything
@@earthscienceclassroom possibly, there's also the sand in-between some walls and I believe the use of magnetism to do a lot of these things. Magnetism has GOT to be the key some way or another
Pitiful! ZERO explaination on how the different stones have been mixed together when they have differnt melting points and densities. More scientism BS.
Firstly, the mineral arrangement is based on cooling and consolidation rates, rate of ascending magma and assimilation/fractionalization. The granite itself is a mixture of 5 principle minerals of different ratios. In other videos this is discussed
@@earthscienceclassroom There ios NO current explaination as to why minerals with different melting points and densities could be so mixed in a slowly cooling environment. Truth problems? How i hate scientism
