What happens to pressure and temperature as you go deeper and deeper into the earth?
What is they increase
100
Which direction does heat move?
What is from warm to cold
100
Which scientist came up with the theory of continental drift?
What is Alfred Wegener
100
Which scientist came up with the theory of sea-floor spreading?
What is Harry Hess
100
Which scientist came up with the theory of plate tectonics?
What is Tuzo Wilson
200
What are the three layers of Earth?
What is crust, mantle, core
200
What are the three types of heat transfer?
What is radiation, convection, and conduction
200
Why was Wegener's theory originally rejected by many scientists and geologists?
What is lacking proof and solid evidence
200
What was the theory of sea-floor spreading?
What is the continents drifted apart because of the sea-floor's continuous and slow expansion
200
What is the theory of plate tectonics?
What is the idea that all continental and oceanic crusts are connected to plates that are in continuous slow motion, which explain why the continents have drifted apart
300
What is the definition of pressure?
What is the force pushing on a surface or area
300
What is the difference between convection and conduction?
What is convection is heat transfer by fluid movement and conduction is heat transfer between solids
300
What is the theory of continental drift?
What is the idea that continents slowly drifted over time from their original supercontinent, Pangaea
300
What is the mid-ocean ridge?
What is the longest chain of mountains in the world that run across the ocean floor
300
What are three different types of plate boundaries?
What is transform, divergent, convergent
400
What is the difference between constructive forces & destructive forces?
What is constructive forces build Earth up while destructive forces slowly wear Earth away
400
Give one example of each: radiation, convection, and conduction.
What is (results vary)
400
What three types of evidence did Wegener find to support the idea of continental drift?
What is landforms, fossils, climate
400
What three types of evidence did Hess use to support his theory?
What is molten material, magnetic strips, drilling samples
400
What is a fault?
What is a break in Earth’s crust where rocks slip past each other
500
What are the two sub-parts of each layer of earth?
What is oceanic crust, continental crust, lithosphere, asthenosphere, inner core, outer core
500
Given the direction of heat transfer, why would your hand feel cold if you hold an ice cube?
What is the absence of heat
500
Give one example for each of the three types of evidence that Wegener found to support his theory
What is (results vary)
500
How do deep-ocean trenches and subduction play a part in sea-floor spreading?
What is deep-ocean trenches are where oceanic crust is subducted and this process prevents the world from continuously expanding
500
Give an example of what could happen at each of the three different plate boundaries
What is transform causes earthquakes, divergent causes rift valley, convergent causes mountains
