Approximately 660 km into the mantle, a discontinuity occurs, affecting the surface crust through processes like plumes and superplumes (aka large low-shear-velocity provinces).]]> 2021-01-20 17:47:08 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106915604 https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106942443 the landmass traps a lot of heat beneath it that the crust ultimately cracks open.]]> 2021-01-20 17:52:34 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106942443 https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106964765 Oceanic and continental plates come together, spread apart,and interact at boundaries all over the planet. At convergent boundaries, continental crust is created and oceanic crust is destroyed as it subducts, melts and becomes magma.]]> 2021-01-20 17:56:58 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106964765 https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106973371 Alfred Wegener, in the first three decades of this century, and DuToit in the 1920s and 1930s gathered evidence that the continents had moved. ]]> 2021-01-20 17:58:44 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106973371 https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106992029 That supercontinent has since split apart, creating the land masses we now recognize as South America, Australia, India, Madagascar, Antarctica and of course Africa. ]]> 2021-01-20 18:02:36 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1106992029 https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1115189962 What causes heat in the Earth's interior is convection in the Earth's mantle. ]]> 2021-01-22 17:56:56 UTC https://padlet.com/staceyannblake1/be1mnmfis5czdfst/wish/1115189962
