100
This is the layer of Earth that contains convection currents.
What is the mantle?
100
This theory states that the Earth is broken up into pieces of crust that move.
What is the theory of plate tectonics?
100
This is any recognizable feature of the Earth's surface that has a characteristic shape.
What are landforms?
100
This boundary occurs when forces pull plates away from each other.
What are divergent boundaries?
100
This type of force raises or builds up surface features.
What are constructive forces?
200
This type of crust is thinner, but is more dense.
What is oceanic crust?
200
This theory states that Earth did not look like it does today and that pieces of the Earth's crust have moved.
What is continental drift?
200
This is the most common type of mountain.
What is a folded mountain?
200
This deformation occurs when rocks slide past one another in opposite directions.
What is shear?
200
This type of force creates deltas, flood plains, sand dunes, and beaches.
What is deposition?
300
These precious metals are found in the Earth's core.
What are iron and nickel?
300
This piece of Wegener's evidence states that plant and animal remains were found on the coasts of different continents.
What is fossil distribution?
300
These are the three types of mountains. (You must get all 3 correct to get the points.)
What are folded, fault-block, and volcanic mountains?
300
This type of fault is caused by compression forces and the rock above the fault moves upward compared to the rock below the fault.
What is a reverse fault?
300
This type of force creates canyons, buttes, U-Shaped valleys, and sea arches.
What is erosion?
400
This layer of the Earth consists of the crust and upper mantle.
What is the lithosphere?
400
This piece of Wegener's evidence states that tropical plant remains are found in Antarctica and glacial remains are found in warmer climates.
What are ancient climates?
400
This is the difference between magma and lava.
What is magma is found inside of the Earth, while lava is when the magma reaches the surface and flows out of the crust?
400
This deformation occurs when rocks are pulled apart and the rock layers are lengthened.
What is tension?
400
This type of force creates mountains and islands but can also reshape mountains.
What is volcanic activity?
500
This layer of the Earth is composed of the middle mantle and allows the tectonic plates to move.
What is the asthenosphere?
500
This is considered to be the main driving force of plate tectonics. It is the constant heating and cooling of molten rock in the mantle.
What are convection currents?
500
These are the three main landscape regions. (You must get all three to get the points!)
What are plains, plateaus, and mountains?
500
This is the type of fault that is caused by shear forces and the rocks move past one another in opposite directions.
What are strike-slip faults?
500
These forces create mountains. Hint: They begin with the same letter! (You must get both correct to get the points.)
What are folding and faulting?
