Defining Globalization

I need support with this Political Science question so I can learn better.

1When it comes to defining “globalization'” compare and contrast Steger’s (contested concept) and Ritzer’s (“globalization” in terms of flows) approaches. How would you conceptualize globalization?

2Having read Ritzer’s and Steger’s chapter two, is globalization a relatively new phenomenon? (Justify your answer.)

3How are imperialism, Americanization and globalization similar? How are they different?
