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.

Mobilist Theory
Wegener´s Continental Drift

The Atlantic Ocean Ridge is an evidence for
Continental Drift and Earth Dynamics
Continental Drift but not for Earth Dynamics

Boundaries amongst plates can be
Divergent
Convergent
Transform
Irregular
According to transform boundaries
They move side ways in opposite directions
They explain the separation and formation of new plates
They explain the union and dissapearance of plates.
According to divergent boundaries
They move side ways in opposite directions
They explain the separation and formation of new plates
They explain the union and dissapearance of plates.
According to convergent boundaries
They move side ways in opposite directions
They explain the separation and formation of new plates
They explain the union and dissapearance of plates.
What is happening here?
There is a convergent boundary and the formation of a new plate is happening.
There is a convergente boundary and the pacific plate is moving below the OK Plate creating lots of volcanoes in the movement.
There is a transform boundary with neither volcanic nor sismological activity.
Which one is not a consequence from Earth´s Dynamics?
Magmatism
Volcanism
Flood
Metamorphism
According to volcanic eruptions they can be classified as
Hawaian, Strombolian, Vesuvian and Pelean
Hawaian and Strombolian
Hawaian, Strombolian, Spokian and Pelean
Malawian, Strombolian, Vesuvian and Pelean
Rocks can show...
Plastic deformation
Elastic deformation
Fractures
Implosions
In an Earthquake...
S and P waves are emmited from the hipocentre to the rest of the planet, being the epicentre the reflection point in the surface.
S waves are emmited by the hipocentre and P waves by the epicentre.
P waves are emmited only in Tsunamis
S waves are emmited by the epicentre and P waves by the hipocentre.
