Bonds
Two atoms produce electrical fields and repel each other. Give an example of the charges for each of these atoms.
Positive and positive
Negative and negative
True or False: The Afar earthquake occurred on a plate boundary.
False
Plates all move in the same direction at the same velocity.
No, False
The net force on an object that isn't moving.
007

True or false: tectonic plate rock can store energy, so it must be an inelastic material.
False
Stability is dependent on this.
Scale
A force with lots of _________________ can break bonds between atoms.
magnitude
A bond between two atoms that are sharing an electron.
Covalent bond
True or False: About 75% of earthquakes occur on plate boundaries.
False - about 90%
Rock deep underground has pressure pushing inward on it. When that rock is brought up to Earth's surface, what happens to the rock's form and why?
The rock expands because the forces pushing inward on it have been removed.
When two objects are in contact, how can we tell which object is exerting a force on the other?
Both objects will always exert a force on the other.
A bond between a positively charged atom and a negatively charged atom.
Ionic bond
What must be happening between atoms in rock when an earthquake occurs?
Bonds are breaking due to high-magnitude force.
Describe the three types of interactions plates have with each other.
Collide/convergent
Separate/divergent
Slide next to one another/transform
Name an object of your group's choosing, and what could happen to that object when a force is exerted on it.
Responses will vary.
Example: a piece of paper will crumple
An atom with a charge will generate an electrical field. These atoms are called ___________.
Ions
What country did the Afar earthquake occur in?
Ethiopia
What is one limitation with using foam blocks as a model to understand how tectonic plates interact?
Answers will vary.
Material type
Magnitude of force
Models are simpler than real-life phenomena
True or false: All matter produces electrical fields.
True: all atoms have at least one charged particle, and their movement within an atom produces electrical fields. These fields can act at a distance on other particles.
Direction of spin of electrons can create fluctuations in the strength of the field.
Without fields, energy could not be stored in tectonic plate rock.
