The theory that all of Earth's continents used to be joined together millions of years ago as one giant landmass called Pangaea.
What is continental drift?
A path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes.
What is the Ring of Fire?
If Africa and South America are placed together, mountain ranges and rock formations on both continents match up.
What are landforms?
Plates colliding.
What is convergent boundary?
Continental-continental collision.
What are mountains?
Climate, landforms, and fossils
What are the evidence Alfred Wegener used to support his theory of Continental Drift.
Measures how closely packed together a substance's atoms are.
What is density?
Glossopteris, a fern-like plant, have been found on several continents separated by large distances.
What are fossils?
Plates spreading.
What is divergent boundary?
Any type of plates sliding.
What are faults or earthquakes?
Unable to prove the driving force causing the movement of continents
Why did most scientist reject Wegener's theory?
The formation of new oceanic crust by the movement of magma out of the mid-ocean ridge.
What is seafloor spreading?
Mesosaurus and Lystrosaurus, both fresh water animals, have been found on landmasses separated by salt water.
What are fossils?
Plates sliding.
What is transform boundary?
Continental-oceanic collision.
What are volcanoes?
My country of origin.
What is Germany?
Along much of the Ring of Fire, plates overlap at convergent boundaries in this type of zone.
What are subduction zones?
Glacial scratches have been found in Africa, which suggests it used to be located closer to the South Pole where it was much colder.
What is climate?
Thinner, more dense, and mostly composed of basalt.
What is oceanic crust?
Continental-continental diverging.
What are rift valleys?
My profession.
What is scientist or meteorologist?
The stretch of the Ring of Fire between the Pacific and North American Plates causes many of these.
What are earthquakes?
Tropical plant fossils have been found in extremely cold locations which suggests these landmasses used to be located in warmer regions.
What is climate?
Thicker, less dense, and composed mostly of granite.
What is continental crust?
Oceanic-oceanic diverging.
What are mid-ocean ridges?
