Modeling Layers of Earth

Front

Which model correctly shows the layers and relative sizes of Earth, including the crust, mantle, outer core, and inner core, using different colors and labels for each layer?

Back

A model with four colored and labeled layers: crust, mantle, outer core, and inner core, each with accurate relative sizes.

Front

Which explanation best supports your choice above? The solid inner core generates the strongest magnetic forces due to its dense composition. The mantle's convection currents drive the magnetic field through friction with the crust. The movement of liquid iron and nickel in the outer core creates electric currents, which generate the magnetic field. The crust's tectonic activity influences the generation of Earth's magnetic field.

Back

The movement of liquid iron and nickel in the outer core creates electric currents, which generate the magnetic field.

A team of scientists sent a deep ocean probe to study the ocean floor. The oceanic crust studied by the submarine is different from the crust found on a continent because:

Back

Oceanic crust is thinner and denser than continental crust.
