List the three types of plate boundaries shown below ---><--- <------> ---> <---
Convergent Divergent Transform
100
What type of plate movement causes a volcano?
Convergent subducting
100
Evidence Wegener relied on to support his theory of continental drift (name 3)
Plant or animal fossils Rock sequences Climate change in Antarctica Fit of continents Glacial evidence
100
The three main types of rock
Sedimentary / metamorphic / igneous
100
What are the two ways volcanoes can form
Subducting plate / over a hotspot
200
At what kind of boundary is new plate material made?
Divergent (ocean floor)
200
Where do we find younger rock, at or away from a divergent plate boundary?
At the boundary (older rock is pushed away by younger rock)
200
What is the relationship between earthquakes, volcanoes, and plate boundaries?
They are all found at the same locations
200
How is igneous rock formed?
Cooling and hardening magma / lava
200
How does one hotspot create MULTIPLE volcanoes?
The plate over the hot spot moves
300
What happens when a continental plate converges with an ocean plate?
Ocean plate (more dense) moves under the continental plate (less dense)
300
What plate boundary type is associated with mountains but not volcanoes?
Continental collision
300
If all the water was drained from the oceans, what would we see?
Solid rock
300
How is sedimentary rock formed?
Pressure
300
How are minerals related to rocks
Rocks are made of minerals
400
How do plates move on Earth's surface
They are carried by the moving rock of the mantle
400
Which plate type is more dense/thin, which is less dense/thick
Ocean - more dense, continent - less dense
400
Where does the heat in the Earth's mantle come from?
The core
400
How is metamorphic rock formed?
Heat AND pressure
400
Why do earthquakes and volcanoes occur at similar locations on Earth?
They happen at plate boundaries
500
An ocean plate meets a continent plate - what happens
Ocean plate subducts, volcanoes form
500
What event happens at transform boundaries
Earthquakes
500
Convection in the mantle - Heated material _______ because it is ____________
Rises, less dense
500
Name two characteristics of plates
Made of rock / Different shapes / Different sizes / They move
500
What is the rock cycle?
Process by which one type of rock is changed to another over long periods of time
