The landform responsible for the Hawaiian Islands.
Hot Spot Volcanoes
Hottest layer
inner core
A supercontinent that existed during the late Paleozoic and early Mesozoic eras.
What is Pangaea?
Which type is made by the accumulation or deposition of mineral or organic particles at Earth's surface, followed by cementation
sedimentary
Is magma more or less dense than the surrounding rock?
Less (That's why it rises)
What causes the movement of the plates?
convection currents (in the molten rock in Earth's mantle below the crust/asthenosphere)

The theory that Earth's lithosphere comprises a number of large tectonic plates which have been slowly moving since about 3.4 billion years ago.
What is the definition of Plate theory.
Every layer in order by name. (4)
(1) crust (2) mantle (3a) outer core (3b) inner core
