The gym floor pushes up on the ball as gravity pulls down on the ball with an equal amount of force.

• The gym floor pushes up on the ball with less force than gravity pulls down on the ball.

• The gym floor pushes up on the ball with an equal amount of force as gravity pulls down on the ball.

• The gym floor pushes up on the ball with a greater amount of force than gravity pulls down on the ball.

• The gym floor pushes up on the ball with an equal amount of force as gravity pulls down on the ball.

Rift valleys can form when fractures in Earth’s crust widen. The valley walls slowly move at a rate of only a few millimeters a year. Which of these best describes the type of tectonic activity that forms rift valleys?
