Cast Practice

The rock cycle is different from the student's model, because in the rock cycle

• processes take a much longer time

• pressure is involved in some processes

• there are both liquid and solid materials

• thermal energy is needed for some processes

The diagram shows a cross section of layers of sedimentary rocks. The types of fossils in each layer are shown. Based on the information in the cross section, select the three statements that are most likely correct.

• Layer C is below Layer B, so Layer C is older.

• Layer A is at the top, so it is the youngest layer.

• The ammonite fossil is above the crinoid fossil, so the crinoid is older.

• There is no coral fossil in Layer D, so corals must have become extinct.

• The gastropod fossils are above the crinoid fossil, so gastropod evolved from crinoids.

Before riding the roller coaster, students are asked to look at a diagram of the track and evaluate the relative potential energy at four points on the roller coaster. The four points, along with their height in meters (m), are shown on the diagram. Which two statements correctly describe the relative potential energy at various points on the track?

• At (1) the potential energy is greater than the potential energy at (3)

• At (2) the potential energy is greater than the potential energy at (3)

• At (3) the potential energy is greater than the potential energy at (4)

• At (4) the potential energy is greater than the potential energy at (2)

A student reviews the model shown and says that, based on the model, a solar eclipse should happen every time there is a new moon. However, solar eclipses occur less often than New Moons. Which feature of the model should be revised to best explain why solar eclipses do not happen every month?

• The model should show that the shape of the Earth's orbit around the Sun is an ellipse.

• The model should show that the shape of the Moon's orbit around the Earth is an ellipse.

• The model should show that Earth's equator is inclined relative to the plane of Earth's orbit around the Sun.

• The model should show that the plane of the Moon's orbit around the Earth is inclined relative to the plane of Earth's orbit around the Sun.
