Alfred Wegener
Alfred Wegener's supercontinent
What is Pangea?
The hypothesis that suggested that continents are in constant motion on the surface of Earth
What is the continental drift hypothesis?
The name of evidence that includes glacial grooves
What are Climate Clues?
This landform is a mountain range in the middle of the ocean
What is a mid-ocean ridge?
These stripes in the seafloor showed that the oceanic crust has been moving constantly over time
What are magnetic signatures?
Aflred Wegener's home country
What is Germany?
The creator of the Continental drift hypothesis
Who is Alfred Wegener?
The name of evidence that includes planet fossils like the Glossopteris
What are Fossil Clues?
This world event lead to the development of echo sounders, which improved our understanding of the seafloor.
What is World War II?
The force through and around Earth caused by the spinning of Earth's inner core
Alfred Wegener's comparison for Continental coastlines
What are puzzle pieces?
The continent supported by Continental drift
What is Pangea?
The name of evidence that includes connecting long mountain ranges across different continents
This process causes new oceanic crust to form along mid-ocean ridges
The state of Earth's magnetic field when magnetized objects point north
What is normal polarity?
Alfred Wegener's missing hypothesis information
What is an explanation for why continents moved?
The original location of continents with evidence of past cold climates
What is the South Pole?
Location of continents when they developed glacial grooves
What is the South Pole or North Pole?
This material builds up pressure under Earth's crust until it pushes up at mid-ocean ridges
What is magma?
This measurement provided evidence that supports the idea that magma is coming up under mid-ocean ridges
What is temperature of oceanic crust?
The location of Alfred Wegener's clues
What is Africa, South America, Australia, India?
The original location of continents with past warm climates
What is the equator?
What are the Caledonian Mountains?
This is the reason old oceanic crust sinks below Continental crust during seafloor spreading
What is oceanic crust's density?
This material contained evidence that supported the idea newer crust is by mid-ocean ridges and older crust is farther away
What is seafloor sediment?
