What are Plate Tectonic Boundaries?
The place where two tectonic plates touch
100
Which layer has the largest mass?
Mantle

Who is Alfred Wegener?
He came up with the hypothesis that the continents were once a whole single land mass and drifted apart.
100
What is the step that test the hypothesis?
Experiment
200
Which boundary is responsible for creating earthquakes?
Transform
200
What is our densest physical layer?
Inner Core
200
What does a balance measure?
Mass
200
Name the evidence Alfred Wegener provided for his hypothesis?
The continents fit together like a jigsaw puzzle Same fossils are on different continents
200
Name the steps of the Scientific Method in order from first to last. *
Purpose/Problem Research Hypothesis Experiment Analysis Conclusion
300
What physical layer moves the tectonic plates?
Asthenosphere
300
What 3 elements is the core mainly composed of?
Aluminum, Silicon, Oxygen
300
Pulling hair back, wearing safety goggles, and putting on a lab coat are all examples of the safety rule _____________
Dress Appropiately
300
Why did some scientist think Alfred Wegener was crazy? *
Some scientist believed he was crazy because his evidence he provided was not enough for them to believe the continents move when they have never seen or felt the Earth move?

What step is the following statement describing: If I add water to the oil, the oil will float on top of the water
Hypothesis
400
What type of convergent boundary is responsible for creating mountains?
CC- Continental Continental
400
Why is the inner core solid?
The inner core is solid because of the extreme pressure exerted on the inner core
400
What safety symbol provides a reminder to use caution when handing hot objects?
thermal safety
400
What is the Continental Drift Theory? *
Earth’s lithosphere (crust) is divided into tectonic plates and moves on the asthenosphere (mantle)
400
Name the step described below: The raspberry plants receiving the most water grew the biggest. Therefore, the hypothesis is supported that this year's raspberries did not get enough rain.
Conclusion
500
What happens when a continental plate and oceanic plate collide together?
The denser oceanic plate sinks back into the Mantle.
500
Name the Chemical Layer with it's Physical Layer. Ex. Core- Inner Core *
Crust- Lithosphere Mantle- Lithosphere, Asthenosphere, Mesosphere Core- Inner Core, Outer Core
500
How do you find density? (Write the equation)
density= mass/ volume
500
What does sea floor spreading explain? *
Sea floor spreading explains how the continents move and was the missing piece of evidence that Alfred Wegener needed when describing his hypothesis of the drifting continents.
500
Why do scientist use the Scientific Method? *
Scientist use the scientific method to help them: solve problems answer questions explain observations (Any of these answers are correct)
