Plate Tectonics 4 Life
What is plate tectonic theory?
Earth's surface is made up of litospheric plates that move over time (Key = pieces and moving over time)
What is the rock cycle
When rock type turns into another type
What is the name of the theorist that came up with continental drift theory?
Alfred Wegener
What is a phenomenon?
An observable fact or event
What are the three plate boundary types?
Convergent (collide) Divergent (divide) and transform (slidey slide)
what are the three types of rocks?
Metamorphic
Sedimentary
Igneous
Why do volcanoes and Earthquakes follow a pattern, like the ring of fire?
Volcanoes and Earthquakes tend to happen along plate boundaries
What layer of Earth are the plates made from?
Lithosphere (crust / mantle)
What is most likely to result at a transforming boundary? (Earthquake or volcano?)
Earthquake
True or false: A metamorphic rock change turn into a metamorphic rock
True
What are the pieces of evidence that Wegener used to support his continental drift theory?
SMRF
What is an aquifer?
Places where water can flow and collect in rock layers under Earth's surface (like sand)
How does each type of plate boundary move? You may use hand gestures to explain
Convergent = Collide
Divergent = Divide
Transform = Slidey slide
What type of rock forms from heat and pressure at subduction zones?
Metamorphic
Two lithospheric plates move toward each other at...
Convergent plate boundaries
What is an aquitard?
A place where water cannot flow through, usually due to density. Think clay
What is one difference and one similarity between Plate Tectonic theory and Continental Drift theory?
Similarities: Pangea, using similar evidence
Differences: continent vs pieces moving, force
How does each type of rock form?
Igneous = Heat
Sedimentary = Erosion / Water
What are the two forces that move plate tectonics?
Convection and gravity
What is convection?
transfer of thermal energy by the movement of matter of different temperatures
