Who was Alfred Wegner? What is Pangea?
Its the scientist that outlined the continental drift theory
pagnea is a giant land mass/
Describe the evolution of pagnea and explain the relationship between tectonic plates and earthquakes.
The pagnea broke uu, forming the continents. This contienents are fixed, but they are moving
because the crust ( the art´s layer wehere we live ) is divided into several plates, called tectonic plates.
How many continents do we have on planet Earth? Paste a map of the world with the name of the continents.

THE PACIFIC OCEAN, THE INDIAN OCEAN, THE ATLANTIC OCEAN, THE ARTIC OCEAN and THE SOUTHERN OCEAN.
The relief is the result of the internal forces of the earth and external agents.Write an example of the action of the internal forces.
Name the external agents that cause the erosion and modeling of the
Earth´s relief.
The relief is the result of the internal forces of the earth ( plate movements, volcanoes, earthquakes... etc. ) and external agents ( rain, wind, temperatures, rivers, groundwhater... etc.)
The internal forces are rosponsible for the origin and the elevation of topographic and external agents cause the erosions and modelin of the earth´s reliefe.
