Changing Earth Events
Why do earthquakes typically cause sudden and significant changes to the Earth’s surface?
Clue: Refer to Plate Boundary Map.
(Earthquake Cosmos A Spacetime Odyssey episode 9 part 10)
A. They gradually wear down rock formations
B. They occur when stress builds up and is released along fault lines
C. They slowly shift tectonic plates over time
D. They result from wind erosion in fault zones
B. They occur when stress builds up and is released along fault lines
Students researched the Lystrosaurus and found that it was a slow-moving, plant-eating reptile that lived over 250 million years ago. Looking at the Fossil Distribution on Pangea evidence that Lystrosaurus inhabited a single landmass that broke apart is that fossils of Lystrosaurus are found _____________________.
A. on different landmasses
B. on glacial ice shelves
C. in seafloor trenches
D. in the oceanic crust
A. on different landmasses
A catastrophic meteor impact would most likely cause what effect on Earth’s surface?
A Slow Effect or A Fast Effect.
It Would Casuse a Formation of large crater and widespread debris (A Fast Effect)
