I'm not sure these links answer your question specifically. What kind of layers depends on whether they were laid by oceans, rivers, in river deltas, etc. What was New York like in the days when the sandstone layers were deposited? Your text materials undoubtedly address this question, or give information to infer an answer.

Answer 2

You can also "google" for yourself. Type in whatever keywords you want into the search engine you have available to you and see what you can find. If one search doesn't find what you need, try again with a variation or more specific set of keywords.
