Layers, Continental Drift, and Plate Tectonic Questions
Between what two layers is the Moho boundary?
a. between outer core and inner core
b. between the crust and asthenosphere
c. between the mantle and the outer core
d. between the oceanic crust and continental crust
What is the function of convection currents in the upper mantle?
a. helps release heat from the core
b. helps reduce pressure in the inner core
c. helps create ocean currents
d. helps drive the movement of the tectonic plates.
Why is the outer core liquid and the inner core solid?
a. the outer core is liquid because its extremely hot but it does not have as
much pressure compacting the atoms.
b. The outer core is liquid because the temperature is much hotter there than in
the inner core.
