Roller coasters are attractions at amusement parks. A cart on a roller coaster approaches the highest point on the coster. as the cart reaches the top, it slows down.

Which statement best describes the energy of the roller coaster as it slows down while traveling to the top of the coaster>

• The cart gains both kinetic and potential energy.

• The cart gains kinetic energy and loses potential energy.

• The cart loses kinetic energy and gains potential energy.

• The cart loses both kinetic and potential energy.

The teacher rubbed a match against a piece of sandpaper. The match started to burn. Which statement best describes the energy changes that occurred?

Describe the geological event that occurs in image A.

• A mountain ridge forms by an inactive convergent boundary.

• A valley forms at an active divergent boundary.

• An earthquake occurs at an active transform boundary.

• A volcano occurs at an active transform boundary.

The illustration shows two objects that have undergone energy transformations. Which of the following is true about the objects?

• Both objects produce a form of thermal energy.

• Both objects have electrical energy present.

• The initial source of energy for one of the object is chemical.

• All of the above.

Convergent boundaries are when plates move toward one another and collide. How are convergent boundaries involved in geological events such as volcanoes?

• When oceanic crust slide past each other without tearing or crushing each other, a volcano forms on the crust away from the plate boundary.

• When oceanic crust slide past each other without tearing or crushing each other, a volcano forms on the crust near the plate boundary.

• When oceanic crust move under a continental crust, a volcanic mountain range forms on the crusts near the plate boundary.

• When oceanic crust is forced over a continental crust, a volcanic mountain range forms on the crusts away from the plate boundary.
