Final Assignment
In this lesson, you have learned how geological processes shape the surfaces of planets and moons over time. You have explored how the natural processes we observe on Earth are the same processes that act on other bodies in the solar system and how they are the same processes that have sculpted planetary surfaces throughout history. You have also investigated how scientists use their knowledge about Earth to study surface features on distant worlds. You will now complete a final project that shares what you have learned.
Begin by reviewing your notes. Click "My Work" and view or print out the screen that pops up.
Then, select one of these four assignments and write a brief essay in response.
- Choose a type of surface feature such as an impact crater, volcano, alluvial fan, canyon, or karst topography. Research an example of the feature on Earth and on another solid object in the solar system. Compare the two examples and describe the similarities and differences. Explain how the features likely formed on each object.
- Research the geological processes that form impact craters. How can surfaces be dated through analysis of impact craters? How can scientists learn about Earth's history by studying impact craters on other objects in the solar system?
- Choose a solid object in the solar system other than Earth and research its geology. What are some of its dominant surface features? Describe the formation and evolution of surface features on the object.
- Research three examples of surface features on Mars that indicate that liquid water once flowed on the planet. How did the features form? Why are scientists interested in finding evidence of water on Mars?
