100
This variable is placed on the x axis of a graph.
What is the INDEPENDENT variable?
100
This type of plate boundary moves apart and causes seafloor features such as ridges, rift valleys, and rises.
What is a DIVERGENT plate boundary?
100
This theory was proposed by Wegner but wasn't accepted in his lifetime.
What is CONTINENTAL DRIFT?
100
This was used in class to see the seafloor features, plate boundaries, and patterns of earthquakes and volcanoes
What is a BATHYMETRIC map?
200
This variable appears SECOND in the question of a lab experiment.
What is the DEPENDENT variable?
200
This type of plate boundary is identified by two plates colliding and resulting in mountains, trenches, earthquakes, and volcanoes
What is a CONVERGENT plate boundary?
200
This type of crust is considered the youngest type, due to subduction.
What is OCEANIC CRUST?
200
This theory has convection as its driving force.
What is PLATE TECTONICS?
200
This model was used to represent the 4 layers of the Earth and focused on the layer of the lithosphere as brittle, hard, cracks.
What is a HARD BOILED EGG (egg shell as a good model of the lithosphere)?
300
This type of observation is based on your 5 senses.
What is a QUALITATIVE observation?
300
Scientific name for mantle.
What is ASTHENOSPHERE?
300
This feature occurs when two plates collide and one is subducted, resulting in the removal of seafloor/rock from the crust and recycling of seafloor.
What is a TRENCH?
300
This theory includes that the crust of the Earth is broken into plates and the plates are made of continental and oceanic crust that shift/move
What is PLATE TECTONICS?
300
This model was used to represent the Lithosphere and the Asthenosphere and the interaction between the two.
What is the MILKY WAY CANDY BAR?
400
Doing this in an experiment allows for your experimental probability to get closer to the theoretical probability.
What is CONDUCT MORE TRIALS?
400
The movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink, which consequently results in transfer of heat
What is CONVECTION?
400
This occurs when plates move apart, magma comes to the surface of the seafloor, hardens, and moves with the plate movement, causing the seafloor to grow.
What is SEAFLOOR SPREADING ?
400
These 3 specific and detailed forms of evidence that are used as justification for PANGAEA, continental drift, and plate tectonics.
What is -Animal fossils found on Africa and South America of fresh water, small marine mammal (unable to swim in salt water and deep water) -Tropical plant fossils found in most continents with large seeds unable to be transported by wind or water; unable to survive in current climate of Antarctica -Rock patterns fit together between South America and Africa
400
This model was used to better understand how the asthenosphere is a solid with fluid properties (it flows).
What is the corn starch/water and silly putty model?
500
These 3 forms of evidence help justify the validity of your lifesaver mania 2 lab.
What is - Use the same size beakers so that equal amounts of liquid will cover the candy -Use the same amount of liquid for each trial -Keep the candy in the liquid for the same amount of time
500
Scientific name for crust.
What is LITHOSPHERE?
500
This explains WHY the plates move.
What is CONVECTION inside the Earth? -core heats mantle -mantle has fluid qualities and rises and cools -movement of mantle causes crust to move
500
3 reasons why continental drift theory wasn't accepted when initially proposed.
What is -Not able to explain WHY it happened -Wegner wasn't a geologist -Not enough evidence
500
This model was a new addition to the classroom last week and demonstrates how a convection current works.
What is the LAVA LAMP?
