Conservative plate boundary - Answer where two tectonic plates slide past each other convergent plate boundary - Answer plates move towards each other and collide Divergent plate boundary - Answer Plates move away from each other Alfred Wegener 1912 - Answer All continents were once joined in a super continent called Pangea. Continental drift caused Pangea to move apart Holmes 1929 - Answer Convection in the mantle is the force behind continental drift oceanographic vessels 1...

Outline the structure of the core. - Answer The core is made up of dense rocks containing iron and nickel alloys. It is divided into the solid inner core and the molten outer core, which has a temperature of over 5000C. This heat is produced due to two processes: primordial heat left over from the Earth's formation and radiogenic heat produced by the radioactive decay of isotopes. Outline the structure of the mantle. - Answer The mantle is made up of molten and semi-molten rocks contai...

What does plate tectonics refer to? correct answers It is a theory explaining the movement of the Earth's crust -Earth's crust is not solid but rather a bunch of pieces (or 'plates') that move on the surface of the Earth. Similar to cracked egg shell. We need all three boundary types for plates to move around Earth's surface: -Convection currents -- drives the movement -Mid-ocean ridge -- spreading center Subduction zones -- oceanic trench site of crust destruction What is the maj...

what is the average movement of a plate in a year ~ 2-5 cm what are the major boundary types ~ diverging, transform, and converging what are transform boundaires ~ where plates slide past one another without creating or consuming crust, example: San Andreas Fault what are divergent boundareis ~ where two plates move apart which creates new earth crust, they occur at midocean ridges example: Iceland what are convergent boundaries ~ two plates colliding with each other causing one plat...
