Okay, so there are some things that can determine characteristics of coastlines. Take for example, estuaries, which are in essence nurseries for fish, where fresh water mixes with the salt water; in these, the coasts are more than likely primary.
Primary coasts are shaped from things relevant to land, like tectonic plates. Secondary coastlines are result of things relevant to marine, like waves.
In all honesty really, I originally took random guesses as to which ones were which.

Sands
The class looked at sand samples this week. With the ones I saw, most of them were white and not very noteworthy.
Anyway, one of the white sand samples, from Cancun, Mexico, were sorted well. It looked like salt, but since it was on a microscope, they looked much bigger, especially when a stronger lens was used.
There was another sand sample I saw that was orange. I don't remember which particular beach it came from, but it once again looked much bigger when looking at the microscope, was very well sorted, and was high on the Wentworth Scale.
