THIS IS GEOLOGY ASSIGNMENT. Please pay close attention to details in the instruction such as APA citation of all resources used, geological location examples etc.

I will like to have it completed in 24 hours. Thanks


Prior to answering the following questions make sure you read all the links in Week 7 Overview and Learning Resources. You are expected to also use outside sources from the course Webliography (under Content), and Internet research. Answer the following questions in APA-style paragraph form and use proper APA citations. Graphics may be used to support your answers, but make sure you cite your source below the graphic.

1) Visit the website for the National Snow and Ice Data Center and then answer the following questions: a) What is the “cryosphere”? Where is most of the cryosphere? What and where is the greatest amount of ice on Earth?

2) Define and differentiate the following terms and give geologic location examples of each: 

· snow

· glacial ice

· alpine glaciers (also called valley glaciers)

· continental ice sheets (also called ice caps)

· icebergs 

· polar sea ice

3) How do glaciers form and move? At present, what is the status of most of the world’s ice (advancing, retreating, or stable)? Why? What are the global consequences of major ice changes on Earth? Why are glaciers one of the best forms of evidence for climate change? Use some specific examples here.

4) Define and describe the following glacial features. How were each formed by glaciers? Give an example geologic location of each; 

· arête

· horn

· cirque

· U-shaped valley (also called glacial trough)

· fjord

5) Discuss the topics of “coastal geology” and “global sea level”. What are the major geologic forces that form coastlines? Describe a couple coastal geological features and how they formed. What are the major causes of global sea level change? What is the relationship between sea level and glacial ice – how do they interrelate? Are both related to global climate change? What are the consequences and hazards of rising global sea level?
