LessonLesson ReviewVocabularyFill in the blank with the term that best completes the following sentence.
1 The is a region of hot, slow-flowing, solid rock between the core and the crust.
2 The is the densest compositional layer and makes up one-third of Earth’s mass.
3 The is the outermost, rigid physical layer of Earth.
Key ConceptsUse this diagram to answer the following questions.
4 Identify Which model of Earth’s interior does this image show?
5 Identify Which of these layers is made mostly of iron and nickel?
6 Compare Explain the differences between the inner core and the outer core.
Critical Thinking7 Compare Explain the difference between the
lithosphere and the crust.
8 Hypothesizing Scientists find dense rock on Earth’s surface that is made of magnesium and smaller amounts of aluminum and silicon. What layer of Earth might this rock help scientists study? Explain your answer.
9 Apply In a model of Earth’s layers that is determined by physical properties, how might the atmosphere be classified? Would it be part of the lithosphere, or a separate layer? Explain your answer.
Lesson Review Answers 1. mantle
2. core
3. lithosphere
4. Earth’s compositional layers
5. core
6. The inner core is solid and dense and is at the center of Earth. The outer core is liquid, less dense than the inner core, and surrounds the inner core.
7. The lithosphere is a physical layer and includes the crust and the upper rigid part of the mantle.
8. mantle; Scientists know the mantle contains more magnesium, and less aluminum and silicon than the crust does.
9. It would be a separate layer. The lithosphere is physically rigid and divided into tectonic plates. The atmosphere is not.
