Multiple Choice

How does a continental plate demonstrate Newton's law of inertia?

• A continental plate will continue to move until it cracks from the pressure applied by Earth's atmosphere.

• A continental plate will continue to move until it crashes into or slides against another continental plate.

• A continental plate will continue to move until it melts into molten rock from the heat of the Sun.

Multiple Choice

Ray is sitting on a couch. Gravity exerts a downward force on him. Based on Newton's law of action-reaction, the other force acting on Ray is the -

• upward force of the couch

• upward force of momentum
