Vocabulary
What term means a break or crack in Earth's crust where movement occurs?
What is a fault
This type of plate boundary is where plates slide past each other horizontally.
Bonus 100 for a feature that forms from this boundary type.
What is a Transform Boundary?
This geologic event occurs mostly at transform boundaries
What is Earthquakes
The two continents that seem to fit together like a puzzle?
What is South America and Africa?
True or false: Earth's surface can only change over millions of years.
What is false?
This theory explains that Earth's crust is broken into moving parts.
What is the Plate Tectonics Theory?
This type of plate boundary is where new crust is created.
Bonus 100 for a feature that forms from this boundary type.
What are divergent boundaries?
An underwater mountain chain formed at a divergent boundary.
+100 if you can name one.
What is a mid-ocean ridge?
This is responsible for moving the continents.
What is seafloor spreading?
This crust is the more dense of the two.
+100 for what this causes
What is the Oceanic Crust
Subducts under Continental Crust
This is the process when one tectonic plate sinks beneath another
What is a subduction?
This type of plate boundary commonly forms volcanoes and trenches.
Bonus 100 if you come to the whiteboard and draw a model of this boundary type.
What is a Convergent Boundary
A curved chain of volcanic islands formed at oceanic-oceanic convergent boundaries.
+100 for naming an example
What is an island arc?
Looking at the map, glaciers are evidence of seafloor spreading. How?
What is Mr. Lunde feedback
The name of the man who created the continental drift theory.
+100 if you say it right.
Who is Alfred Wegener?
This feature forms where dense oceanic crust bends downward into the mantle at a convergent boundary, creating the deepest parts of the ocean.
What is a trench?
Why do volcanoes form at oceanic-continental convergent boundaries, but not at continental-continental convergent boundaries?
Continental crust does not easily subduct or melt to turn into magma unlike oceanic crust.
There are 4 processes that can form at an oceanic-continental Convergent boundary. Name 3 of them
+100 for all 4
What is earthquakes, mountain building, trenches, volcanoes?
This internal earth process drives plate motion and seafloor spreading.
What is convection currents?
The Scientist who was able to explain seafloor spreading.
Who is Harry Hess.
This theory explained that all earth's landmasses were once all connected as one.
What is Continental Drift Theory?
This plate boundary type we would expect earthquakes, but not volcanoes.
+100 for explaining why
What is a Transform Boundary
Plates slide past each other without melting or magma formation
Name two geologic features that form at an oceanic-oceanic boundary.
What is island arcs, earthquakes, trenches, volcanoes?
Looking at the 4 maps, explain 3 of the maps and how they support continental drift.
What is Mr. Lunde's choice.
Scientist can use magnetic polarity patterns and crust age to determine the direction and speed of plate movement. Explain this process.
What is Mr. Lunde's choice
