General Knowledge
This is the name for the large pieces of Earth's surface that move and interact to cause earthquakes and volcanoes.
What are tectonic plates?
This theory explains how Earth's outer layer is broken into large, moving pieces that interact and cause geological changes.
What is the theory of plate tectonics?
This type of boundary occurs where two plates move away from each other.
What is a divergent boundary?
These two continents fit almost perfectly together, like puzzle pieces, which helps further support the plate tectonics theory.
What is Africa and South America?
This scientist found evidence for Pangea and proposed the theory of continental drift.
Who was Alfred Wegener?
This (theorized) landmass existed about 300 million years ago before breaking apart due to plate movements.
What is Pangea?
At this boundary, plates slide past each other horizontally, like along the San Andreas Fault.
What is a transform boundary?
These remains of living things that lived long ago have been discovered in matching coastlines on different continents.
What is fossils?
This natural disaster is most commonly associated with plate tectonics.
What are earthquakes?
This process creates currents in the mantle that causes tectonics plates to move.
What are convection currents?
This boundary involves two plates pushing against one another, often creating mountains or trenches.
What is a convergent boundary?
Alfred Wegener was missing this crucial piece of evidence to fully prove his theory on plate tectonics.
What is convection currents?
This type of plate is thicker and less dense than its counterpart.
What is a continental plate?
This term refers to the slow movement of continents over millions of years, first proposed by Alfred Wegener.
What is continental drift?
This process occurs when the denser plate sinks under the less dense plate.
What is subduction?
Fossils of the same plants and animals are found on continents now separated by this large body of water.
What is the ocean or Atlantic Ocean?
This underwater process at divergent boundaries creates new crust.
What is seafloor spreading?
This layer of Earth is home to the tectonic plates.
What is the Crust?
Mid-ocean ridges are formed at this type of plate boundary.
What is a divergent boundary?
These landforms seem to line up and match on different continents that are now no where near each other.
What are mountains or mountain ranges?
