Evidence for Plate Tectonics
Animals like the lystrosaurus have been found on continents an ocean away from each other- it is impossible for us to find fossils this far away from each other unless they was once a supercontinent
What type of plate movement describes a divergent boundary?
What type of plate movement describes a convergent boundary?
What type of plate movement describes a transform boundary?
Plates slide in opposite directions against each other
What formed the supervolcano at Yellowstone?
Hot spot
What creates new ocean basin (seafloor spreading)?
mid-ocean ridges created at divergent boundaries
What type of formation occurs at a continental-continental convergent boundary?
mountains- like the Himalayas
There is one type land formation that forms at a transform boundary. What is it?
fault lines
The name of the principle that states that the oldest rocks and fossils will be closer to the bottom of the Earth's crust is:
superposition
What is the name of the world's largest lake, that formed from a continental rift valley at a divergent boundary, and has 20% of Earth's freshwater?
Lake Baikal
What type of formation can occur at a oceanic-continental convergent boundary?
ocean trenches, volcanic arch, volcanoes, mountain ranges
Explain why transform boundaries cause Earthquakes.
rapid motion of plates; buildup of pressure over time due to plates sliding against each other
The Appalachian (eastern United States) and Caledonian (Europe) Mountain ranges have the same type of rock and are the same age. This is evidence of what hypothesis supporting Plate Tectonics?
Continental drift
What is the specific plate boundary that has not been observed enough by scientists to make accurate predictions of its behavior?
Divergent: continental-oceanic
What is the name of the world's deepest ocean trench that goes down 11 kilometers?
What is the name of the fault line in California that caused an earthquake which caused 500 deaths and thousands of destroyed homes/buildings?
San Andreas Fault
What is the name of the scientist that proposed the hypothesis of continental drift?
Alfred Wegener
Describe what a magnetic reversal is.
??
There is a circular pattern of volcanic activity across several of the Earth's oceans due to subduction of oceanic plates (primarily convergent boundaries). What is this called?
The Ring of Fire
In the video we watched about transform boundaries, the woman said that transform boundaries act like ______ on a _______. (hint: the world is round- like a ball)
stitches on a baseball
