In 1910, he noticed that South America and Africa appeared to fit together like puzzle pieces. He was certainly not the first person to notice this. But he was intrigued by the idea and thought a lot about it. He wondered if the two continents were once joined and then moved apart? He set out to find evidence to support or refute this idea. ]]> 2019-01-28 19:28:21 UTC https://padlet.com/alaysia_georges/y8c2z426bktq/wish/325116383 alaysia_georges https://padlet.com/alaysia_georges/y8c2z426bktq/wish/325817098 2019-01-30 13:28:25 UTC https://padlet.com/alaysia_georges/y8c2z426bktq/wish/325817098 🄲🄾🄽🅅🄴🄲🅃🄸🄾🄽 🄲🄴🄻🄻🅂 alaysia_georges https://padlet.com/alaysia_georges/y8c2z426bktq/wish/325829345 Deeper material is hotter and so it rises.

This crust is not a solid shell; it is broken up into huge, thick plates that drift atop the soft, underlying mantle.
The plates are made of rock and drift all over the globe hence called a continental drift. They move both horizontally and vertically. Over long periods of time, the plates also change in size as their margins are added to, crushed together, or pushed back into the Earth's mantle. It is the heat generated by radioactive decay inside the Earth which drives this process. These plates are from 80 to 400 km (50 to 250 miles) thick.
At some stage in history a process called continental drift began. We do not know when because the rocks have been squashed and changed so much since then, but it is important because it is still happening today. Some people think that it caused the Ice Ages.

The lava cools to form new seafloor. Later more lava erupts at the ridge. The new lava pushes the seafloor horizontally away from the ridge axis.
