Good question, so it is actually about the definition of lithosphere and asthenosphere, once the bottom of a particular lithosphere reached a higher temperature magma, it will partially melt or become less brittle so changing to a part of asthenosphere thus it becomes thinner. This changing process has been explained by another video we made called 'three ways to melt the mantle '
Should not include Singapore, Hong Kong, and Shanghai in the list of ports built on passive continental margins. They are built on back arc basins, which are very near subduction zones, with volcanoes, earthquakes, and active tectonics. Those ports should be considered as built on active margins.
Lithosphere is brittle how it thins up??

Thank you, this was super helpful for revision for my geography class, I now fully understand passive continental margins! thanks again :))
Thank you! Kate for your kind feedback! We are glad!
Great, Thanks.
Great video. What type of software do you all use to make these awesome animations?
Glad you enjoyed it! The visuals were drawn in Adobe Illustrator and later animated using Adobe After Effects.

Hong Kong is a rocky assembly of mountainous islands, I would agree that it isn't built on a passive continental margin.
