Plate Tectonics Flashcards
What are the 3 Types of Plate Boundaries?
Transform, Convergent, Divergent
What is Convergent Plate Boundary?
When two plates collide and one plate slides beneath the other (also known as subduction). Many earthquakes happen because of this.
What is Transform Plate Boundary?
When two plates slide past each other.
What is Divergent Plate Boundary?
When two plates move away from each other.
What are Hotspots?
Volcanic spots fed by the underlying mantle.
What Forces Causes Tectonic Plates to Move?
The heat from radioactive processes within the Earth’s interior
Who Originally Proposed Continental Drift and What Was Their Evidence?
Alfred Wegener, his evidence was showing comparisons between continents
How did new discoveries about the sea floor contribute to the widespread acceptance of the
theory of plate tectonics
The Tharp-Heezen Map illustrated the geological features that characterize the seafloor
