EARTH SCIENCE

Unit IV Assessment- 200 WORDS EACH

Question 1 : Recall from your reading about the nature of volcanoes, and in your own words, compare and contrast aa and pahoehoe lava in appearance and how they form.

Question 2 : In your own words, briefly explain how a caldera forms from principle types of volcanoes.

Question 3 : According to the figure below, give an approximate age for the Dakota Sandstone and for the Wasatch Formation. Explain what evidence you used to determine this.

Question 4 : Volcanoes are generally not preserved in the geologic rock record because they are usually eroded away. However, the various materials erupted from volcanoes are often found preserved in the rock record. From what you have learned about the different principle types of volcanoes, how could you infer what type of volcano erupted in a given area based on the type of volcanic deposits now found as layers of rock? Give specific examples, and briefly discuss how some materials may be linked to different types of volcanoes.

Your response should be at least 200 words in length.

Question 5 : Discuss the geologic history of the area where you live or grew up. Discuss some of the major factors that might have played a role in shaping the local terrain (major rivers, sea-level changes, volcanoes, ancient sea beds, glaciers, earthquakes, etc.). If needed, spend a few minutes researching your state on-line, (search for your state and "geologic history"). Be sure to list all sources that you use in your answer.

Based on the descriptions of the other students, respond to a student who lives in a place that you would like to live or visit. What is it about the geology of the place that intrigues you? Be sure to keep the discussion based in science.

Human Resource Management CLASS- 200 WORDS

Organizations have two choices from where to source candidates for jobs: external or internal. Each has its pros and cons. For this unit's post, select a sourcing option, internal or external, and discuss some pros and cons for your choice. You may want to conduct additional research to gain a better understanding of the ripple effect each one has.
