The crust and the litosphere are the same.

• True

• False

The mantle is 2900 Km deep and peridotite is the most present metal within it.

• True

• False

Which system of heat transmission is the most used in the Earth dynamics?

• Radiation

• Conduction

• Convection

The planet does not show any movement and earthquakes and volcanoes are related to the action of religious manifestations directly or indirectly.

• Fixist Theory

• Mobilist Theory

• Wegener´s Continental Drift

• Earth Dynamics Theory

There was an original continent known as Pangea, and according to different evidences (Geological, Natural, Paleological and Paleoclimatical) there was movement until nowaday´s configuration.

• Fixist Theory

• Mobilist Theory

• Wegener´s Continental Drift

• Earth Dynamics Theory

Based on Wegener´s Theory and with the use of better technology, the Earth shows dynamics based on heat exchange of the interior of the planet that cracks the litosphere into plates that move because of this energy.
