this is about the early civilizations of egypt, nubia,sumaria, assyria, persia, israel, indus valley,aryans, china.

the question is:
in which ways did cultures or civilizations come in contact and, as a result, aspects of one culture were adopted by another?

For the most part, they didn't -- at least not for a long time.

Travel, however, developed by means of overland trade routes, as well as rivers and the coastlines of seas and oceans (the Mediterranean Sea and the Indian Ocean, etc.)

New discoveries are constantly being made, though -- for example:

If you are doing a report, you should probably choose two or three of these civilizations to concentrate on. It'll be better and more productive to do so.

How to conduct thorough and effective searches for yourself ---

You are searching for information that is so specific that you have to be prepared for the possibility that some may be online and some may not. In addition to searching on the Internet, you also need to make best friends with the reference librarian(s) in your local or college library.

At this webpage, you can go immediately to the search sites (first three columns across the top) -- or even better you can scroll down until you see the section called HOW TO SEARCH THE INTERNET. Those are the links to start with. You'll not only learn how to come up with good search terms, but also how to evaluate the webpages you get as results. Some will be good and others will be garbage. You need to know how to tell the difference.

My favorite way to search is to go to Google's advanced search page
< http://www.google.com/advanced_search?hl=en > and put my search words or phrases into the first or second search box (either "all the words" or "exact phrase"). However, there many other strategies for searching you can use, and the HOW TO SEARCH THE INTERNET section will help you best.

Happy searching!

They all came to study at Luxor.

It is unclear how the civilizations mentioned in your question specifically came into contact with each other and adopted aspects of one another's culture. However, trade routes, travel, and interactions along river systems and coastlines could have facilitated contact between these civilizations. For example, the Silk Road and the maritime trade routes in the Mediterranean Sea and Indian Ocean would have allowed for cultural exchange between civilizations. Additionally, conquests, migrations, and diplomatic relationships could have also led to the adoption of certain aspects of one culture by another. Further research into specific historical events and interactions between these civilizations would provide more concrete examples of cultural exchange.
