Effects of Plate Tectonics
Evidence of Plate Tectonics
Convergent, Divergent or Transform
100
The name of the landmass when all the continents were attached together.
Pangea
100
Draw a model to show the movement of plates along a transform boundary
100
How does plate tectonics make a mid ocean ridge.
a mid ocean ridge is two plates next to each other that are moving away from each other.
100
How are continents that fit together like puzzle pieces evidence of plate tectonics.
It makes sense that they were together as one piece of land then broke apart.
100
Two plates that move away from each other.
divergent
200
The two types of rocks that make up oceanic crust and continental crust
Basalt & Granite
200
Draw a model with labels of Lithosphere
200
How does plate tectonics lead to sea floor spreading?
Lava comes up from a mid ocean ridge. It hardens to create new sea floor.
200
How is similar fossil types found between continents evidence of plate tectonics?
The species that made the fossil most likely lived together at one point then the land moved later on.
200
two plates that slide next tot each other.
transform
300
A theory explaining how the plates that make up the Earth’s crust move over the mantle.
Plate Tectonics
300
Draw a model with labels of a subduction zone.
300
How does plate tectonics make a subduction zone?
Plates move toward each other then the more dense oceanic crust slides under the less dense continental crust. The oceanic plate begins to melt in the mantle.
300
How are similar rock types found between continents evidence of plate tectonics?
The rock most likely formed together then separated to different continents.
300
Two plates that move toward each other.
convergent
400
The driving force of plate movements.
What is convection currents?
400
Draw a model with labels of a mid-ocean ridge.
400
How does plate tectonics make an earthquake?
Often along transform boundaries pressure builds up and causes the plate to move suddenly.
400
How is rock that is the same age on both sides of a ridge but gradually gets older evidence of plate tectonics?
It shows magma is coming from the ridge and hardening into new rock over time.
400
A subduction zone is an example.
Convergent
500
The rigid outer part of the Earth. It includes the Crust and upper mantle.
Lithosphere
500
Draw a model of convection currents in the mantle causing a convergent boundary
500
How does plate tectonics make mountains?
When plates come together, they push on each other and the land begins to pile up.
500
List 5 pieces of evidence of plate tectonics.
similar fossils and rock types found between continents, ridges that magma comes from, rock that is the same age on both sides of a ridge but gradually gets older, continents that fit together like a puzzle, etc.
500
The Mid- Atlantic ridge is an example.
Divergent
