These "cables" in the Nervous system send electrical signals throughout the body

This famous California fault line is a classic example of a Transform boundary.
What is the San Andreas Fault?
This is the first step of the scientific method, where you look at the world around you
What is observation?
This pump is the "engine" of the Circulatory system
What is the heart?
Transform boundaries don't create crust; instead, the friction usually results in these "shaking" events
What is an earthquake?

What are plates?
This is an "educated guess" or a testable prediction.
What is hypothesis?
This is the primary organ of the Integumentary system that protects you from the outside world.
What is the integumentary system?
This is the rigid, outermost layer of Earth that makes up the plates.
What is the litosphere?
This group is treated exactly like the experimental group except it does not receive the independent variable, serving as a standard for comparison.
What is the control group?
In the Digestive system, this organ uses acid and "collision" (churning) to break down food.
What is the stomach?
This event occurs when a denser oceanic plate dives under a lighter continental plate.
What is subduction?
This type of variable represents the data or "effect" being measured, such as the height of a plant or the speed of a chemical reaction.
