22.1. Structure of the Earth

Try these first

1. 1.

   What is the outermost layer of the Earth called?

   Hint

   Think of the Earth as a fruit; which part is the most exposed?

2. 2.

   What layer lies directly beneath the crust?

   Hint

   This layer is crucial for volcanic activity.

3. 3.

   What is the lithosphere composed of?

   • Crust and Outer Core
   • Crust and Upper Mantle
   • Mantle and Inner Core

   Hint

   It's a combination of the outer layer and the top of the mantle.

4. 4.

   True or False: The inner core is in a liquid state.

   • True
   • False

   Hint

   Consider the concept of pressure in relation to state of matter.

5. 5.

   Analyze how the movement of tectonic plates at divergent boundaries can lead to earthquakes and volcanic activity. Provide specific examples in your answer.

   Hint

   Consider how new crust formation impacts geological stability.

6. 6.

   Compare and contrast the characteristics and formations of oceanic and continental crust. What implications does this have for tectonic activity?

   Hint

   Think about where each type of crust is found and how their properties influence tectonic interactions.
