Evelyn is making a model of Earth to show how the physical layers correspond to the compositional layers. Which of the following should Evelyn show in her model?

• The physical layers exactly match the compositional layers.

• The crust is the only compositional layer not included in the physical layers.

• The physical layer of the asthenosphere includes the compositional layer of the crust.

• The physical layers of the inner core and outer core form a single compositional layer.

Scientists divide Earth into three main layers. Each layer has a different chemical composition. Which is the innermost layer of Earth?

• Earth's innermost layer is the core.

• Earth's innermost layer is the mantle.

• Earth's innermost layer is the lithosphere.

• Earth's innermost layer is the asthenosphere.

Earth is divided into compositional layers based on chemical composition. Which compositional layer is a hot, convecting layer of rock?

• core

• plate

• crust

• mantle

Earth can be divided into five layers: the lithosphere, the asthenosphere, the mesosphere, the outer core, and the inner core. Which properties are used to make these divisions?

• compositional properties

• physical properties

• chemical properties

• elemental properties

Madelyn drew a diagram of Earth showing one way that scientists have divided it. She included the core, the mantle, and the crust. Madelyn divided her diagram into three layers based on which of the following?

• relative density

• physical structure

• geographical location

• chemical composition

Earth has five layers based on physical characteristics. The diagram below shows these five layers. Which letter represents the asthenosphere, the soft layer on which the tectonic plates move?

• A

• B

• C

• D

How do the physical properties of a substance differ from its chemical properties? (Lesson 4)

• Tools are needed to measure chemical properties, but not physical properties.

• All physical properties can be seen with the unaided eye, while chemical properties cannot.

• Chemical properties can be used to identify a substance, but physical properties cannot.

• Physical properties can be observed without changing the identity of the substance, while chemical properties cannot.

Which of these BEST describes the motion of atoms in solid iron as it melts? (Lesson 3)

• The atoms slow down and gather together

• The atoms speed up and move past one another.

• The atoms vibrate in place but cannot move past one another

• The atoms are separated from their electrons, leaving the electrons negatively charged.
