100
The thin, outermost layer of the Earth, the part we live on
What is the CRUST
100
The plate boundary where two plates collide into one another
What is Convergent Plate Boundaries
100
How are mountains formed?
What is when two continental plates collide into each other
100
What is the name of the guy that theorized about Continental Drift?
What is Alfred Wegener
100
What evidence did the Continental Drift theory have to prove that the continents were once one? (Give at least 2)
What is Mesosaurus fossils, fern fossils, rock structures, glacier grooves, climates
200
The layer of the Earth underneath the Asthenosphere located in the mantle
What is the MESOSPHERE
200
When two plates slide horizontally past one another
What is transform plate boundaries
200
During a subduction zone, magma comes up and create what?
What is volcanoes
200
What was the name of the guy who theorized about sea-floor spreading?
What is Harry Hess
200
Why can you find the same animal fossils on two different continents?
What is they were once connected
300
The liquid, dense center of the Earth
What is the Outer Core
300
When two plates separate from one anther
What is divergent plate boundaries
300
How do earthquakes happen?
What is convergent plate boundaries or transform
300
What is the pangaea?
What is when our continents were one big super continent (all one)
300
How come the sea-floor rock are only 180 million years old, while continent rocks are over 4 billion?
What is sea-floor is a cycle, the newest layer comes up through an ocean ridge when tectonic plates separate and cools and hardens, then it pushes the other layers to the outside. The oldest layers are on the outside and once get to the end go down the trenches into the Earth.
400
The layer of the Earth that moves the plates
What is the Asthenopshere
400
When two plates collide, but one plate slides underneath the other plate
What is subduction zone
400
When plates separate (divergent) what happens?
What is there is a gap that becomes filled with magma, which then cools and hardens and becomes the new sea-floor. (sea-floor spreading)
400
What was sea-floor spreading?
What is when two plates separate, magma comes up fills the gap cooling and turning into new sea-floor. The oldest layers are on the outside, and eventually will fall in the trench and go into the Earth and turn into magma, starting the cycle all over again.
400
What layers did the milky way represent in our Earth?
What is Chocolate=lithosphere Carmel/nougat= asthensphere
500
The layer of the Earth where the plates are located
What is lithosphere
500
What are the 3 main types of plate boundaries
What is Convergent, Divergent, Transform
500
What is the famous fault that is beneath California?
What is San Andres Fault
500
What is continental drift theory?
What is all the continents were once one and slowly drifted to where they are now.
500
What are convection currents?
What is what moves the plates, hot material rises..cools off and sinks, then heats back up thus starting the cycle which moves the plates.
