To recap, nominal scales have labels, the value and order of options don't matter. Ordinal scales have labels, the order matters, but the value doesn't. Interval scales have labels, the order matters, and the values matter but there's no zero.

In summary, nominal variables are used to “name,” or label a series of values. Ordinal scales provide good information about the order of choices, such as in a customer satisfaction survey. Interval scales give us the order of values + the ability to quantify the difference between each one.
