The Continental Crust consists mainly of this rock. $100
What is Granite? $100
The scientists who study the forces that make up and shape the Earth. $200
Who are geologists? $200
The part of the mantle that is solid rock, but can flow like a liquid. $300
What is the asthenosphere? $300
The parts of the Earth that make up the lithosphere. $400
What are the crust and the upper mantle? $400
The layers of the Earth from the outermost layer the inner most. $500
What are the crust, mantle, outer core, inner core? $500
The transfer of energy through empty space. $100
What is radiation? $100
The transfer of heat by the movement of a heated fluid. $200
What is convection? $200
In the convection current of a pan of soup, the cooler, denser fluid does this. $300
What sinks to the bottom? $300
This happens to the density of a fluid when it becomes hotter. $400
What is a decrease in density? $400
This describes how convection currents occur in the mantle. $500
The rock in the lower mantle is heated by the core below The rock in the lower mantle is heated by the core below. As it is heated the rock becomes less dense and rises through the asthenosphere. As the rock rises it cools and becomes more dense. When the rock becomes dense enough it sinks back through the asthenosphere. $500
He proposed the Theory of Continental Drift. $100
Who is Alfred Wegener? $100
The 3 types of evidence Wegener used to support his theory. $200
What are fossils, rocks, landforms (continents’ shapes, mountain ranges, etc.), climate? $200
The name of the supercontinent that began to break apart about 250 million years ago. $300
What is Pangaea? $300
Daily Double
Scientists rejected Wegener’s theory because he could not provide this. $400
How the continents move? $400
This climate evidence supported the Theory of Continental Drift. $500
What is Glossopteris (tropical fern fossils) found in Iceland showing that Iceland must have been closer to the equator or Glacier marks found in Africa indicating that Africa must have been closer to the poles? $500
A long chain of underwater mountains that forms along areas of seafloor spreading. $100
What is the mid-ocean ridge? $100
The process that continually adds new material to ocean floor. $200
What is sea floor spreading? $200
The process by which oceanic crust sinks beneath another plate into the astheosphere. $300
What is subduction?. $300
This is a description of seafloor spreading. $400
As 2 plates are forced apart by convection currents in the asthenosphere, molten rock rises through a crack and forms a ridge of volcanic mountains. As more molten rock rises the old ocean floor is pushed away. The further the seafloor is from the mid-ocean ridge, the cooler and denser it becomes. Eventually the seafloor becomes dense enough to plunge back into the mantle forming a deep ocean trench. $400
Two types of evidence for seafloor spreading. $500
What is drilling samples (shows oldest rocks are found farthest from mid-ocean ridge), and magnetic stripes (pattern is the same on both sides of the ridge)? $500
A break in Earth’s crust where rocks have slipped past each other. $100
What is a fault? $100
The separate sections (pieces) of the Earth’s lithosphere. $200
What are tectonic plates? $200
A plate boundary where 2 plates slip past each other, while moving parallel to the plate boundary. $300
What is a transform plate boundary? $300
A valley that forms on land along a divergent plate boundary. $400
What is a rift valley? $400
These are the 3 types of plate boundaries. $500
What are convergent, divergent, and transform? $500
This is the difference between the inner and outer core. $100
What is a solid inner core and a liquid outer core? $100
The oldest oceanic crust is found here. $200
What is furthest away from the ocean ridge or close to the trench? $200
This is Wegener’s theory of continental drift. $300
What is the theory that states that all continents were once joined as one landmass which slowly moved apart? $300
This produces the Earth’s magnetic field? $400
What forms when the liquid outer core forces the solid inner core to spin? $400
These are 3 different types of convergent plate boundaries. $500
What are oceanic/oceanic, oceanic/continental, continental/continental? $500
Final Game Questions Earth’s Plates

What are the Pacific & Indo-Australian plates at a convergent boundary
And the winner is…..
