How Do I Get Some Heat in Here?
The Big Shift
Under and Over
My Side or Your Side
A Bit From Here and There
100
The transfer of heat through empty space.
What is radiation?
100
The large, ancient landmass that was composed of all the continents joined together.
What is Pangaea?
100
An undersea mountain chain where new ocean floor is produced.
What is a mid-ocean ridge?
100
A break in the Earth's crust where masses of rock slip past each other.
What is a fault?
100
Evidence that you can see or touch directly. For example, rock samples.
What is direct evidence?
200
The transfer of heat by the movement of a heated fluid.
What is convection?
200
Came up with the theory of continental drift.
Who is Alfred Wegener?
200
The process that creates new sea floor as plates move away from each other at the mid-ocean ridges
What is sea-floor spreading?
200
A deep valley that forms where two plates move apart. Can be found underwater, along the large ridges that run throughout the ocean or in continental crust.
What is a rift valley?
200
Plates/crust mostly made of basalt and are 3-5 miles thick.
What is oceanic?
300
A current caused by the rising of heated fluid and sinking of cooled fluid.
What is a convection current?
300
Same species of plant/animal fossils found on different continents separated by oceans.
What is fossil evidence of Continental Drift?
300
The process by which oceanic crust sinks beneath a deep-ocean trench and back into the mantle at a convergent plate boundary.
What is subduction?
300
World's highest mountains forming a boundry between South and East Asia are an example of this type of boundary.
What is a convergent boundary?
300
American geologist who hypothesized that the sea-floor spreads apart at the mid-ocean ridge as new crust is added.
Who is Harry Hess?
400
The transfer of heated particles to other particles through direct contact. Usually happens with solids but can sometimes happen with liquids.
What is conduction?
400
The hypothesis that states that the continents once formed a single landmass, broke up, and drifted to their present locations
What is the idea of Continental Drift?
400
Pulls older, denser oceanic crust down beneath a deep-ocean trench.
What is gravity?
400
The types of plate boundaries that move away from each other?
What are transform and divergent boundaries?
400
When the location where the north magnetic poles exists becomes the south magnetic pole, and the south magnetic pole becomes the north magnetic pole.
What is magnetic pole reversal?
500
The movement of heat from a warmer object to a cooler object.
What is heat transfer?
500
He couldn't provide an explanation for the force that pushes and pulls the continents.
What is why Wegener's ideas were rejected?
500
Circular currents in the mantle that cause subduction and seafloor spreading.
What are convection currents?
500
Canadian scientist who combined what geologists know about sea floor spreading, Earth's plates, and continental drift into a single theory; plate tectonics (1965).
Who is J. Tuzo Wilson?
500
In most places, the oceanic crust of this ocean is attached to the continental crust so there are very few trenches. The spreading ocean floor has no where to go so as the ocean floor spreads, the continents along its edges also move.
Where is the Atlantic Ocean?
