Plate Tectonics 1
Geological events found at Convergent boundaries that are oceanic to oceanic
What are deep sea trenches?
Layer of the earth that has the convection currents
What is mantle?
The older Hawaiian islands are found here.
What is further away from the Hot Spot?
The movement of plates over Earth’s surface is known as this.
What is plate tectonics?
boundary where major earthquakes are located.
What is transform boundary?
The Hawaiian Island chain was formed by this.
What is a hot spot in the middle of an oceanic plate?
Boundaries where two plates slip past each other are known as this.
What are transform plate boundaries?
To continental plates pull apart and form these.
What is rift valley?
Proposed the theory of Continental Drift.
Who is Alfred Wegener?
In sea-floor spreading, molten material rises from the mantle and erupts here.
What is the Mid Ocean Ridge?
Subduction is where a continental plate meets an oceanic plate- what effects can happen
What are earthquakes and volcanic eruptions?
These are 4 pieces of evidence Wegner identified for continental drift.
What are puzzle-piece continental drift, distribution of fossils, placement of similar rocks, and indicators of ancient climate?
Continental drift and Seafloor Spreading are caused by this
.
What is convection currents in the mantle?
The large landmass that made up all of the continents.
What is Pangaea?
the lithosphere is broken up into these
What is tectonic plates?
process where convection currents move the plates creating new earth at the mid ocean ridge and move older crust outward at both sides.
What is seafloor spreading?
Convergent boundaries of two continental plates result in this landform.
What are mountains?
This is a process of heating, rising (less dense) cooling (become more dense) and sinking moving the tectonic plates.
What is convection currents
?
Boundaries where plates move apart are known as this.
What are divergent plate boundaries?
Mid-ocean ridges are this type of plate boundary.
What are divergent plate boundaries?
The volcano below Yellowstone like the Hawaiian islands was formed by this.
What is a hot spot?
density and temperature increase as you go in this direction.
What is deeper into the earth?
Features that rise up high above the deep seafloor as a long chain of mountains where two oceanic plates pull apart at divergent boundaries
What are mid-ocean ridges?
When a denser plate is dragged under a less dense plate into the mantle is known as this.
What is subduction?
Boundaries where plates move together are known as this.
What are convergent plate boundaries?
Older crust at edges, new crust at mid-ocean ridge and magnetic reversal is evidence to support this process.
What is evidence of of Seafloor Spreading?
Two continental plates push together, buckle and form mountains at this type of boundary.
What is Convergent Boundary (collision)?
One plate is pushed down by the less dense plate.
What is Convergent Boundary (subduction)?
Two plates pull apart
What is divergent boundary
Major earthquakes occur
What is transform boundary?
