100

An object distance from another object is changing

What is motion?

100

These kind of objects make good reference points.

What are stationary objects?

100

More than a dozen of these make up earth’s outer layer

What are plates?

100

The rate at which velocity changes.

What is acceleration?

200

Steepness of a line that shows the rate of change

What is slope?

200

Distance the object travels per unit of time

What is speed?

200

Plates move very what?

What is slowly?

200

When you are slowing down, it is known as what?

What is deceleration?

300

Speed of an object in a given direction

What is velocity?

300

Basic unit of length

What is the meter?

300

These are cracks in the Earth's outer layer but don't always lie along the continental edge.

What are boundaries between plates?

300

Riding down a hill is an example of acceleration or decceleration?

What is acceleration?

400

A place or object used for comparison to determine if something is in motion

What is a reference point?

400

Motion can be graphed with a line graph showing the rate of change between what two things.

Distance and time

400

These are the two types of plates

Continental and Oceanic

400

A car stopping at a red light is an example of acceleration or decceleration?

Deceleration

500

To find what type of speed would you divide total distance traveled by the total time.

What is average speed?

500

The rate at which an object is moving at a given instant rate

What is instantaneous speed?

500

This theory states that Earth’s plates move slowly in various directions.

What is the Theory of Plate Tectonics?

500

The equation for finding acceleration.

final speed-initial speed divided by time
