What is true about how oceans and continents move?

• Continents move from earthquakes, oceans remain motionless

• Gravity pulls continents across the oceans

• Both remain motionless

• Both continents and oceans are on plates that move constantly but slowly

Why do the continents have a puzzle-like fit?

The Mantle floats directly on the

• Crust

• Lithosphere

• Inner core

• Outer core

An object floats because it is

• More dense

• gravity

• Less dense

• Magnetism

Convection currents are made by

• Rock magnetism

• Hot crust sinking, cold outer core rising

• Hot magma rising, cold magma sinking

• Tides
